Thrombosis, the formation of a blood clot (thrombus) that tends to plug functionally normal blood vessels, is one of the major causes of death in Western societies. Pathogenesis of Atherosclerosis Judith Berliner, Ph.D. This means that it is anterograde in veins or retrograde in arteries. Thrombin in turn converts fibrinogen to fibrin. Pathogenesis of early thrombus formation in experimental vein graft. Result of Thrombus? Whether your application is business, how-to, education, medicine, school, church, sales, marketing, online training or just for fun, PowerShow.com is a great resource. Prof. J. Plevkova MD, PhD. Accordingly, baboons treated with ticlopidine and heparin displayed a significant reduction in platelet deposition and microvascular occlusions in the ischemic basal ganglia. Their relationship to naturally occurring thrombus formation in humans is unknown, but they do offer a model for studying thrombi that are spatially and temporally defined. Thrombosis. 1961 Jan-Feb; 1:3–25. Thrombus formation on disrupted atherosclerotic plaques or arterial erosions frequently causes acute coronary syndromes. Definition • Formation of blood clot inside blood vessel. 4. You just clipped your first slide! The dominant influence, and the one factor that by itself can lead to thrombosis, is endothelial injury.2,5,6 Endothelial Injury: Endothelial injury causes subendothelial collagen exposure and platelet adherence, among other changes; many factors can contribute to the injury, including hypertension, vasculitis, scarred valves, bacterial endotoxins, cholesterolemia, and chemicals … The first was changes in the coagulability of the blood, the second changes in the formed elements of the blood, the third changes in the circulatory blood flow andthelast changesin thevessel walls. Departments of Pathology and Medicine Division of Cardiology David Geffen School of Medicine at UCLA – A free PowerPoint PPT presentation (displayed as a Flash slide show) on PowerShow.com - id: 3f4967-MzFiM Presentation Summary : exposure of the pro-thrombogenic basement membrane just below the endothelial cells thrombosis the formed thrombus will further block the lumen of the blood But even nonhospitalized, ambulant patients and apparently healthy individuals may encounter this problem. × Atrial fibrillation is the commonest underlying card … Etiology and pathogenesis of thromboembolism Herz. 3- may be life-threatening. CRAWFORD T. Morphological aspects in the pathogenesis of atherosclerosis. More data are needed to understand the determinants of healthy versus dysfunctional response and immune markers for protection and the severity of disease. DEFINITION THROMBOSIS is the formation of a clotted mass of blood within the cardiovascular system. Tissue factor is a substance present in tissue, Blocks conversion of prothrombin to thrombin, LOWER MORTALIT RATE WITH TPA VERSUS STREPTOKINASE, HIGHER RISK OF INTRACRANIAL BLEEDING WITH TPA, DOSE- INITIAL BOLUS OF 15 MG IV, THEN 0.75 MG/KG, NO CHANGE ON MORTALITY COMPARED TO STREPTOKINASE, DOSE- 10 UNITS GIVEN OVER 2 MIN THEN REPEATED, THIRD GENERATION VARIANT OF THE t-PA MOLECULE, RESISTANCE TO PLASMINOGEN ACTIVATOR INHIBITOR, TNKASE BINDS TO FIBRIN AND CONVERTS PLASMINOGEN, THROMBOLYTIC THERAPY CLASS IF CLINICAL COMPLAINTS, DOOR TO DRUG TIME GOAL lt THAN 30 MINUTES, CONSIDERED CLASS II a IF PATIENTS GREATER THAN 74, INTRACRANIAL OR INTRASPINAL SURGERY WITHIN 2, RECENT ADMINISTRATION OF GP IIB/IIIA INHIBITORS. - Predictors of Acute, Subacute and Late Stent Thrombosis After Acute MI Primary Angioplasty in the Horizons AMI Trial George D.
