For subclavian insertion may need to use towel rolls to avoid kinking of the catheter when turning patient to side or prone fungus gnats miracle gro cheap 200 mg nizoral with mastercard. Cerebral spinal fluid may be drained continuously or intermittently as prescribed by the physician fungus gnats peppermint tea buy online nizoral. Consistency in the level of the drainage system is necessary for accurate interpretation of pressure readings. Note number of spontaneous and ventilator-assisted breaths at baseline, during and following interventions. Monitor standard vital signs (heart rate and blood pressure) at baseline, during, and following interventions. Assess level of consciousness, agitation, and delerium during each examination and intervention. Review neurosurgical assessment, determine whether physical therapy cranial nerve assessment is indicated. Assess static and dynamic sitting balance on edge of bed and in wheelchair, with upper extremity support. Note number of health care providers necessary to assist patient with balance in supported and unsupported sitting postures and transfers. Assess skin integrity at each visit while turning patient for each postural drainage or mobility intervention- particularly bony prominences, the back of the head, areas where brace touches skin, heels. Inspect skin each time binder, splints, and elastic stockings are donned and doffed. Assess alignment, fit, and movement while patient wears the resting hand splints and abdominal binder. Assess resting posture in wheelchair and static and dynamic postures while sitting on the edge of the bed with assistance. Anthropometric characteristics Arousal, attention, and cognition Assistive and adaptive devices Cranial nerve integrity Gait, locomotion, and balance Integumentary integrity Orthotic, protective, and supportive devices Pain Posture Range-of-motion Muscle strength and sensation which test was administered. Table 19-19 outlines the critical components of a physical therapy examination and evaluation for the mechanically ventilated patient. The patient would also have an understanding of how to assist himself with deep breathing and coughing exercises and instruct a caretaker in pressure relief. It was anticipated that the patient would tolerate sitting on the edge of the bed with moderate assistance of one individual and sitting in a wheelchair with the legs dependent for 2 to 4 hours per day. It was hoped that the patient would not develop any skin breakdown or thromboemboli. The therapist and nurse positioned the patient in the left side-lying position, one-fourth turn from prone. There was also no air bubbling in the waterseal chamber of either chest tube, so it was unlikely that the patient had developed a bronchopleural fistula. Aspiration was less of a concern, because the feeding tube passed through the stomach and extended to the small intestine; however, the tube feeding was turned off prior to head-down positioning. The therapist noted and marked which hole in the strap was used to secure the vest. Although the patient had right rib fractures, which were noted as a precaution, it was necessary to administer manual techniques to assist in secretion clearance on the right side because the patient could not be mobilized or cough sufficiently to clear retained pulmonary secretions. When properly performed, there is no known increased risk in the development of extrapleural hematomas, hemoand/or pneumothorax. A gentle form of vibration is used over rib fractures by some physical therapists. After 10 minutes of percussion to the right lower lobe, the therapist noted crackles with auscultation, which was indicative of secretions loosened in the small airways. A cough was stimulated with the suction catheter, but no secretions were suctioned.

Operators prefer the laser over directional atherectomy in longer and more complex disease [46] fungus yeast treatment discount 200 mg nizoral fast delivery, probably because of the relative ease of its use and the avoidance of multiple catheter removals and reinsertions antifungal nail spray proven 200 mg nizoral. Also, with the advent of the Turbo-Tandem and Turbo-Power catheters, more effective directional lasing is likely to be achieved. Finally, laser has been applied to facilitate lysis in dialysis graft and venous application [47,48]. More data are needed on laser-facilitated lysis in lower extremity arterial applications. Bivalirudin, a direct thrombin inhibitor, is a more predictable anticoagulant during endovascular procedures. In contrast to heparin, it has the added advantage of inhibiting free and bound thrombin and thrombin-induced platelet activation [49,50]. Maceration or disruption of thrombotic lesions is likely to further activate platelets and thrombin. Vorapaxar has not been widely adopted because of higher bleeding risk and expense. Based on the symptom onset, a thrombus can be acute or subacute (within 2 weeks) or chronic (more than 2 weeks). In this case, the use of rotational atherectomy devices such as the Jetstream device or photo-thrombectomy with the laser may provide better acute procedural results. Also, the more organized the thrombus, the more likely the need for a longer lysis time, higher thrombolysis dose, and subsequent bleeding complications. We believe that embolic protection is an important safeguard against distal embolization when treating thrombotic lesions because of the high embolic potential in these patients.

This electron micrograph shows an evolving platelet thrombus in which a number of platelets have become activated and have bound tightly together fungus mites buy nizoral with mastercard. Thrombin binds to protease-activated receptors on endothelial cells fungus gnats lavender oil discount 200 mg nizoral mastercard, activating the cells and thus promoting platelet adhesion and cytokine release and triggering endothelial cell production of platelet-activating factor [18]. This is of particular clinical relevance in the context of subarachnoid hemorrhage, in which thrombin accumulates at the site of the bleed and amplifies cerebral vasospasm; the contractile response to thrombin is then typically augmented by the upregulation of protease-activated receptor-1 [23]. The P2Y1 Gq-protein-coupled receptor mediates the platelet structural changes, mobilizes calcium, and stimulates the phospholipase C and inositol phosphate signaling pathways. We will here explore further the role of platelets in atherosclerosis, and in doing so will focus on their ability to modulate the trafficking of inflammatory cells, mainly myeloid cell types, within the arterial wall. We will then proceed to address the role of platelets in modulating inflammation, with particular reference to atherosclerosis, and examine the evidence that antiplatelet therapy may modify expression of the aforementioned biomarkers. In the final part of this chapter, based on these considerations, we will explore the possibility that antiplatelet therapy may be a useful novel approach to inhibiting atherogenesis. Patients with chronic inflammatory diseases, such as inflammatory bowel disease and rheumatoid arthritis, carry an increased risk of developing cardiovascular disease in later life, suggesting a possible link between inflammatory processes and atherogenesis [42]. Monocytes comprise approximately 1%e8% of circulating leukocytes and have a half-life of around 1e3 days, after which they move into tissues and differentiate into macrophages or dendritic cells [45]. Monocytes migrate to sites of local inflammation where their roles include phagocytosis and pro- or antiinflammatory cytokine production. The Role of Monocytes in Atherosclerosis Monocytes play a pivotal role in the development of atherosclerosis via formation and deposition of lipid-laden foam cells within the arterial tunica intima, which contribute to plaque instability [46]. Monocytes are further implicated in the development of atherosclerosis and plaque rupture due to their involvement in plaque neovascularization. As plaque size increases, impaired oxygen diffusion develops, and the proximal cells of the tunica intima become hypoxic [47]. Evidence suggests that circulating monocytes may also serve as endothelial progenitor cells, further amplifying angiogenesis [48,53]. Intraplaque hemorrhage is one of the principal determinants of plaque rupture [55]. These differences may be partially explained by the heterogeneity of subject groups recruited to the studies, as well as differences in monocyte gating strategies during flow cytometry. Activated platelets adhere to damaged endothelium and locally mediate both inflammatory and thrombotic events via the secretion of cytokines and interactions with leukocytes, which result in chemotaxis and development of an inflammatory milieu within the arterial wall. P-selectin levels are independently associated with carotid atherosclerotic lesions in humans [74]. The pharmacological efficacy of the multiple classes of antiplatelet agents in counteracting antiatherogenic mechanisms is variable. Their distinct mechanisms of action may have differing effects on the intracellular pathways that finally lead to P-selectin expression on activated platelets [79]. The possible role of antiplatelet therapy in countering atherogenesis will be explored further later in this chapter. These molecular interactions are favored by specific conformational changes that Mac-1 undergoes upon cell stimulation [84], which result in increased affinity of Mac-1 to the aforementioned platelet ligands. In keeping with this, neutrophil depletion in animal models has been shown to effectively counteract monocyte recruitment into atherosclerotic lesions [90]. This technical limitation makes it difficult to delineate the clinical relevance of their formation to cardiovascular outcomes. With regard to their possible proatherogenic role, this may be attributed to their effect on the biological function of myeloid cells. The diverse actions of netrin-1 in cardiovascular and renal disease are presented. Netrin-1 directly modulates survival and migration of different cell types, including cardiomyocytes, leukocytes, and endothelial and tubular renal cells, through engagement of cellspecific receptors, as indicated.

The latter antifungal tube purchase 200 mg nizoral with visa, indeed fungus ease purchase genuine nizoral on-line, frequently constitute formidable obstacles by diverting or deflecting the guidewire tip to buckle away or even forcing it to penetrate and perforate the lumen of the vessel. A recanalization channel was created with resultant restoration of antegrade flow. Clinically, the patient improved with no further angina pectoris and shortness of breath. As previously mentioned, these lesions frequently contain layers of organized thrombus of various ages. Once most or all the thrombotic component is extracted, contrast injections can precisely assess the residual plaque. This intriguing finding attests to the fact that thrombus removal clears the way for subsequent successful dilatation and precise stent delivery and deployment [10]. During percutaneous coronary intervention such channels enable guidewire crossing, which should be followed by thrombus removal before plaque modification by balloon and stenting. Edwards Registry of Cardiovascular Disease Collection, Nasseff Heart Center, United Hospitals, University of Minnesota School of Medicine, St. The Role and Impact of Thrombus in Formation and Revascularization of Chronic Total Occlusions Chapter 21 315 amenable to thrombolysis [12,13]. In the absence of bleeding complications, low-dose thrombolytic therapy can be continued until complete thrombus removal occurs and then consideration must be given to completion of the revascularization, usually by means of stenting. In this scenario the distal cap is first traversed by the guidewire, which is advanced retrogradely along the native vessel toward the proximal cap and then crosses beyond onto the ascending aorta. Consequently, as the thrombus yields to manipulations of the guidewire tip it permits guidewire traversing. These include standard, coated, and fortified cutting balloons; balloon-mounted radio frequency combined with thermal energy; acoustic ultrasound energy catheters; vibrational energy; magnetic navigation; blunt microdissection catheters; and collagenase infusion. Both technologies utilize direct thrombus engagement for removal of its constituents. AngioJet the principle of activation for rheolytic thrombectomy is based on the creation of saline jets inside the catheter, which travel backward from the tip at very high speed, creating a negative pressure zone from the Venturi effect. This offers a combined pharmacologic thrombolytic effect with powerful mechanical extraction, a synergistic strategy aptly termed "power thrombectomy" [16]. Clinically, the excimer laser has been found a useful interventional tool for targeted thrombus removal strategy [19]. The physical process caused by the laser activation is the creation of acoustic shock waves that propagate along the irradiated vessel. These waves carry a dynamic pressure front, which collides with the fibrin mesh within the thrombus. The process disrupts and breaks the fibrin fibers, resulting in fibrinolysis and decreased thrombus size [20]. This laser also alters the aggregation kinetics of platelets, causing a reduction of platelet force development and inhibition of the platelet activity. This phenomenon of platelet stunning is dose dependent and most pronounced at high levels of energy fluence, such as 60 mJ/mm2 [21]. High success rates of 86%e90% for the excimer have been reported in these occlusions [23]. Total occlusions are mostly long-standing lesions that contain layers of old, wellorganized thrombus within calcified and fibrotic plaques. In such instances the laser can be used successfully for recanalization of the target [24]. A third-degree atrioventricular block developed, accompanied by hypotension and worsening chronic renal failure. A year earlier both the right coronary artery and its corresponding saphenous vein bypass graft angiographically demonstrated complete occlusion. The disease is represented by long total occlusions containing a large thrombus content [11]. The interventionalists also successfully applied the excimer laser for treatment of chronic and subacute thrombotic occlusions of the lower extremity peripheral arteries [27]. A beneficial experience with the laser was reported as well by other interventionalists [28e31].

Standard venous timing of contrast results in dense opacification of the dural sinuses and produces a conspicuous "empty delta" sign-filling defect in the setting of a thrombus as well as adjacent dural enhancement and venous collateral drainage [95 fungus yard pictures buy nizoral 200 mg overnight delivery,96] fungus or bacteria buy nizoral with amex. These venous occlusions can also present with associated findings such as delayed venous outflow, venous collateralization, and corticovenous reflux. Although safe when performed at experienced centers, catheter-based angiography carries small risks of embolic infarct, vascular injury, hemorrhage (intracranial and groin), infection, allergic reaction to contrast, or complications associated with anesthesia. The risks of angiography are generally warranted only in the setting of an unclear diagnosis following noninvasive imaging and when an interventional treatment is being considered. Regardless of etiology and duration, an international normalized ratio goal of 2e3 is recommended [66]. The use of this or similar anticoagulation paradigms is supported by four clinical trials [101e104]. While the base of evidence is relatively small, these groups draw similar conclusions and prescribe similar treatment paradigms that have become the current standard of care. The treatment regimen for pediatric patients is similar to the adult strategy with appropriate dose adjustments. This practice is based on less evidence, as there are no randomized prospective trials available to guide management. This practice is supported by both the findings of the Berlin and Dutch randomized controlled trials and several observational studies [107e110]. Mechanistically this practice is supported by the notion that deceasing the propagation and extent of thrombus burden should decrease the amount of venous backpressure and thus decrease the chance of expanding or generating new hemorrhagic venous infarct. Likewise, if the patient is suffering from the secondary effects of thrombus-induced venous hypertension or infarct such as vision loss, seizure, or intracranial mass Thrombosis of the Venous Vasculature: Diagnosis and Management Chapter 33 487 effect, treatment of these symptoms should be initiated. In patients who present with acute-phase seizure or who have hemorrhagic lesions on their admission imaging, current recommendations are to continue antiepileptic treatment for 1 year [98]. In such patients, or in patients with negative repeat imaging, lumbar puncture may be necessary to exclude chronically elevated intracranial pressure, which should subsequently be treated [111e113]. Endovascular thrombectomy and/or thrombolysis may be an effective adjunct to systemic anticoagulation in patients who demonstrate symptom progression despite medical management. However, some observational studies show a trend toward improved outcomes in patients with significant thrombus burden and baseline poor prognosis [98,114,115]. The goal of endovascular therapy is to reestablish some degree of flow within the occluded sinus. If a channel of flow can be established via thrombolytic injection, or mechanical disruption of the clot, the flowing blood has the potential to lyse or stabilize the residual thrombus. These techniques confer a significant risk of sinus or adjacent structure damage, which can lead to intracranial hemorrhage or venous infarction. Therefore, endovascular interventions should be reserved for the most severe cases and be attempted only by experienced practitioners at centers with appropriate neurosurgical and neurocritical care support. In this subset of severe patients, death was usually secondary to focal mass effect from hemorrhage resulting in herniation and diffuse cerebral edema [71,118,119]. In the subset of patients who presented with intracranial hemorrhage, 21% had died or become dependent at 6-month follow-up [69,121]. Likewise, in children and neonates the delayed complication, dependency, and death rates are all higher than in adults [71,85,86,123]. In neonates the mortality rates may be as high as 25% and only 22% have an impairment-free survival [86,124]. In patients with neurological deterioration, approximately one-third will demonstrate new parenchymal lesions on repeat imaging [66,71]. Therefore, the topic continues to be an active area of academic investigation with many unanswered questions and inadequately supported treatment paradigms. Together these studies should provide improved diagnostic and treatment strategies and, it is hoped, improve outcomes in the most severely affected patients.

The overall coupling behavior from T1 to T12 antifungal nail polish discount 200 mg nizoral free shipping, including the effect of the rib cage fungus anatomy buy nizoral overnight, which is therefore more representative, exhibits a strong coupled ipsilateral axial rotation during primary lateral bending as well as a small coupled contralateral lateral bending during primary axial rotation when loaded with pure bending moments, whereas during flexion/extension movement, there is no considerable coupling behavior. In vivo studies, however, showed that coupled motions of the thoracic spine can vary considerably between individuals (Willems et al. The eccentric applied loads lead to an asymmetric pressure distribution below the compressed disc, similar to degenerated lumbar discs (Horst and Brinckmann, 1981). Together with the decreased disc height, the thoracic discs therefore exhibit more solid material properties compared with the more fluid material behavior of healthy lumbar discs. Therefore, when considering thoracic spinal stability, distinction must be made between overall, segmental, and vertebral stability. The overall stability of the thoracic spine is mainly a combination of the stiffness and strength properties of the differently shaped vertebral bodies and intervertebral discs; the entire thoracic spine, disregarding the rib cage, has a compressive failure force of about 2 kN, a compressive stiffness of about 300 N/mm, and an energy-absorbing capacity in compression of about 10 Nm (Yoganandan et al. In the case of high flexion-compression loading, posterior ligament injury is produced prior to vertebral body compression, leading to additional loads on the vertebral body, which itself exhibits a compressive failure load of about 10 kN, a compressive stiffness of about 1000 N/mm, and a compressive strength of about 4 N/mm2 (Maiman and Pintar, 1992). The vertebral body compressive strength thereby highly correlates with the bone mineral density, which increases in inferior direction (Singer et al. However, isolated vertebral body fractures most likely do not cause spinal instability, while combined injuries, for example of the vertebral body and the posterior elements, very likely produce clinically relevant instability. The thoracic spinal motion segment is stiffest in axial compression direction while allowing moderate shear (Panjabi et al. Because of its specific three-dimensional structure, it is also more flexible in flexion and axial rotation compared to extension and lateral bending (Table 2), while the axial rotation torsional stiffness is additionally increased by up to 50% by both compression and tension forces (Goodwin et al. Table 2 Average Stiffness Coefficients of Thoracic Spinal Motion Segments Axial Stiffness in N/mm Tension Compression Anterior/posterior shear Lateral shear 780 1240 110 110 Flexion Extension Lateral bending Axial rotation Torsional Stiffness in Nm/degree 2. The posterior rib cage elements, especially the rib-vertebra articulations, contribute to spinal stability by restricting motions and thereby increasing the intersegmental stiffness, whereas the anterior rib cage elements, especially the sternal complex, provide strength and energy-absorbing capacity to increase the overall stiffness. Consequently, there is less stabilizing musculature in the thoracic spine compared with the cervical or lumbar spine but the same relative load bearing properties. In fact, all rib cage structures contribute to thoracic spinal stability, although the integrity of the anterior rib cage is the most important stabilizing factor (Liebsch et al. Moreover, the intact rib cage distinctly increases the neutral and elastic zone stiffness in all motion directions (Mannen et al. The biggest effect of the rib cage on spinal stability can be observed in axial rotation (Liebsch et al. This corresponds to the finding that median longitudinal sternotomy, which is mostly performed during cardiac surgeries, decreases the stability mainly in axial rotation and less in flexion/extension or lateral bending (Liebsch et al. Using a static multibody model that included rigid body elements for all bony structures and deformable elements for the discs, ligaments, and costal cartilages, they found, after validating the model by in vitro experiments, that the costovertebral joint geometry strongly influenced their mechanical response and that the compression tolerance of the thoracic spine was distinctly increased by including the rib cage. They found that the rib cage predominantly had an influence on thoracic spinal compressive forces and muscle activation during spinal motion tasks, while reducing and distributing the compressive forces compared to a model without a rib cage in mild flexion and hyperextension. They concluded that height and age-sex interaction were the dominant factors for the size of their model, which was designed to analyze traumatic injuries to the thorax.

However antifungal vitamins minerals order generic nizoral on line, the related techniques are relatively new ascomycete fungus definition cheap 200 mg nizoral visa, and their mid-to-long-term clinical outcomes and complications have been available for only a few years. The authors found that with both techniques the spinal cord tension can be significantly decreased but that the reduction of the spinal height causes dural buckling that can lead to compression of the neural structures (Safain et al. Then the authors tested the specimens by performing a multidirectional bending test and found that the anterior support can increase the construct rigidity. Consequently, they suggested using interbody cages associated with posterior fixation in order to avoid the need for revision surgeries. The use of supplementary rods at the osteotomy level was investigated on cadaveric specimens by Hallager and colleagues (Hallager et al. Concerning computational studies, Hato and colleagues studied a closing-opening correction osteotomy with a numerical model of the thoracolumbar spine, creating various models, varying the kyphotic angle, and considering different degree of osteoporosis (Hato et al. The model was subsequently modified to study the effect of instrumentation, namely posterior fixation and fixation with supplementary rods at the level of osteotomy (Luca et al. Results indicated that stiffer configurations (double rods and rods with higher diameter) induced a marked reduction of the stresses on the instrumentation, but might slow down healing at the osteotomy site because of the decreased load transferred through the anterior column.

Dominant clinical findings relate to the stenosis of blood vessels or the trachea tree fungus definition purchase nizoral now. Important considerations: the location of mediastinal tumors will often suggest the correct diagnosis antifungal toenail cream cheap nizoral 200mg otc. Morphological imaging criteria such as the distribution of enhancement within a mass and the morphological appearance of the tissue (homogeneity, necrosis, calcifications, fat content, relationship to neighboring structures with possible displacement, invasion, or cystic components) can further narrow the diagnosis. Note In the reporting of mediastinal masses, it is important to describe the exact size, location, and relationship of the mass to neighboring structures. Sudden onset of clinical complaints requiring emergency diagnosis may result from a fast-growing tumor or from decompensated stenosis due to a slower-growing tumor. When vascular narrowing occurs gradually, circulation can be maintained by the development of collaterals, and superior vena cava syndrome does not occur. If the recurrent laryngeal nerve is damaged by compression or infiltrated by a mass, the result is unilateral vocal cord paralysis with hoarseness. Persistent hoarseness may be the only symptom of a small tumor impinging on the recurrent laryngeal nerve. Iodine deficiency leads to enlargement of the thyroid gland in patients with a euthyroid or hypothyroid metabolic state. Approximately 15 to 30% of all adults, depending on eating habits, have an enlarged thyroid gland. If more than 50% of the enlarged gland extends into the chest, the patient is said to have an intrathoracic (or retrosternal) goiter. This feature is useful in distinguishing goiters from other diseases in the superior mediastinum, since other tumors as well as mediastinal widening due to other causes will rarely cause tracheal displacement. A sectional imaging diagnosis of intrathoracic goiter relies on two main criteria: the mediastinal mass is in continuity with the thyroid gland. Note In patients with longstanding hoarseness and no associated cold symptoms, exclusion of a tumor involving the recurrent laryngeal nerve is necessary. The initial imaging study is often a plain chest radiograph, which can demonstrate the location and extent of a mediastinal tumor. The radiographic signs described earlier are helpful in determining the location of a mass. Sectional imaging can then accurately define the extent of the lesion while also revealing the compression or possible infiltration of adjacent organs. Most extend into the anterior mediastinum, and some may even extend as far as the middle or posterior mediastinum. Patients usually present clinically with visible enlargement of the thyroid gland, typically located at a supraclavicular level in the midline. The goiter may become symptomatic due to tracheal displacement, and large goiters may cause tracheomalacia with cough, dyspnea, and inspiratory stridor. Differential diagnosis Enlargement of the thyroid gland may be a result of thyroiditis or thyroid carcinoma. Thyroid carcinoma may also contain calcifications, so the presence of calcifications is not a useful criterion for benign/malignant differentiation. Iodine 123 (123I) (or iodine 131 [131I) thyroid scintigraphy can detect nodules that do not concentrate iodine. Suspicious nodules are then evaluated by ultrasoundguided fine needle aspiration biopsy to exclude thyroid carcinoma. The sternum (S) and aorta (A) serve as landmarks, as the thymus is located between them. It has smooth margins and its enhancement characteristics are identical to those of thyroid tissue.

This article highlights the diagnosis and management of challenging cases, which illustrates the prevalence and impact of cardiovascular thrombus as encountered through the experience of a major academic center. The benefits and limitations of imaging modalities such as angiography, intracoronary ultrasound, optical coherence tomography, and echocardiography are reviewed and discussed. Contemporary cardiovascular imaging allows thrombus to be directly visualized for diagnostic and therapeutic purposes. The acoustic homogeneity of thrombus allows the achievement of precise interpretation regarding the composition and age of the targeted thrombus. Among these tools, the optical coherence tomographye and ultrasound-based technologies are often superior to the commonly utilized angiography. As illustrated by multiple cases throughout this chapter, the incorporation of multiple imaging modalities affords practitioners a comprehensive assessment of cardiovascular thrombus. There is also a concurrent need to reduce the risk of pharmacotherapy-induced bleeding caused by antiplatelet therapy with or without adjunct anticoagulant drugs [1]. The objective of this chapter is to offer the reader a spectrum of clinical situations encountered in a major academic medical center, in which intracardiac or intracoronary thrombosis resulted from underlying cardiovascular disease or catheter-based interventions. Similar to Pictures at an Exhibition by the famous Russian composer Mussorgsky, the chapter is formatted as a promenade in which the reader is invited to look at the pictures in the spirit of the composer, namely "allegro giusto. Intracoronary thrombosis: distinction between acute, subacute, and organized thrombus 2. Thrombosis following catheter-based structural heart interventions Cardiovascular Thrombus. Thrombus recognition can be challenging when there is only limited contrast between the thrombus and the surrounding blood speckles. Diagnostic accuracy can be improved by assessing a moving image as opposed to a single still frame. Moreover, the acoustic homogeneity of a thrombus might allow one to draw conclusions regarding the composition and age, as an ultrasound image is based upon the differences in acoustic impedance within and between tissues. The acoustic impedance of a tissue is defined by the product of its density and acoustic velocity (Table 22. Sound waves that travel through a homogeneous tissue will be less reflected, thus creating a darker image, while a sound traveling through a tissue with a heterogeneous architecture will yield a brighter picture due to a more pronounced difference in acoustic impedance. One needs to recognize that the limitations of a diagnostic modality (sensitivity, specificity) necessitate a critical assessment and the formulation of a differential diagnosis. However, light at approximately 1400-nm wavelength is used to generate the image and not sound, which carries major implications. This is, however, at the expense of a limited penetration depth into the tissue (approximately 1e2 mm). Second, blood has to be removed from the field of view, as light is scattered by erythrocytes. This results in a high contrast between the lumen (which appears signal-poor or "black") and the vessel wall. Therefore, it is simple to identify additional structures, such as intraluminal or mural thrombi. Postmortem studies analyzing thrombi reveal that white thrombus consists mainly of platelets and white blood cells, while red thrombus mainly contains red blood cells. Middle: A later phase of the process of thrombosis during which the so-called lines of Zahn develop [4]. The thrombus appears as an inhomogeneous area around the catheter with preserved lumen (arrows in the right image). The difference between postmortem and antemortem thrombi needs to be recognized (Table 22. Suspicion of an obstructive plaque (top left, c) with obstruction of the coronary artery (top left, d).
