Morphology of thrombus (cont.) Inflammation is triggered, causing tenderness, swelling, and erythema. Atherosclerosis, chronic disease caused by the deposition of fats, cholesterol, calcium, and other substances in the innermost layer of endothelium of the large and medium-sized arteries. PE can be classified according to : The presence or absence of hemodynamic stability (hemodynamically unstable or stable). 1. 2004 Feb. 56(2):356-62. . 1990 Jan. 18(1):42-6. . A thrombotic stroke is a type of ischemic stroke that occurs when a blood clot, also called a thrombus, forms and blocks blood flow through the artery in which it formed. 3 However, there are other types of emboli air, fat, amniotic fluid, and septic (from bacterial invasion of the thrombus). FAT EMBOLISM SYNDROME BACKGROUND EPIDEMIOLOGY CAUSES PATHOPHYSIOLOGY CLINICAL FEATURES DIAGNOSTIC CRITERIA … Looks like you’ve clipped this slide to already. In the GISSI-3 trial, the incidence of LV thrombus among those with an anterior infarction increased to almost 18% for patients with a LV ejection fraction of less than 40% as compared with less than 10% of those with a higher 194 VENOUS THROMBOEMBOLISM Compositeterm for DVT &PE The presence of thrombus with in deep veinsis termed as deep vein thrombosis It is a life threatening condit… artery or one of its branches by material (eg, thrombus, tumor, air, or fat) that originated elsewhere in the body. Crit Care Med. PGIMER & DR.R.M.L HOSPITAL Thromb Haemost. MRI has similar reported sensitivity and specificity for detecting thrombus in the renal vein of 86–94% and 75–100%, respectively, as well as 100% accuracy for detecting IVC thrombus [ 79 , 80 ]. Fat is deposited in the liver as a result of a number of metabolic derangements.

In a post-hoc analysis of prospective acquired data, a cutoff value > -70 HU of the perivascular fat attenuation index (FAI) around the proximal right coronary artery was found to be predictive of increased all-cause mortality 10. Fibroblasts eventually invade the thrombus, scarring vein wall and destroying valves. • Normal fluid homeostasis is maintained by vessel wall integrity, intravascular pressure and osmolarity within certain physiologic ranges.• Changes in intravascular volume, pressure, or protein content, or alterations in end 3. FAT EMBOLISM SYNDROME & PULMONARY EMBOLISM FARAH AZUREEN ABD ZAIM 2. INTRODUCTION Problems of the vascular system includes disorders of the arteries and veins. Color Doppler sonography has reported sensitivities and specificities for detecting thrombus in the renal veins of 75% and 96%, respectively, with 100% accuracy for detection of thrombus in the IVC . Wong MW, Tsui HF, Yung SH, Chan KM, Cheng JC. Severity assessment . Overweight or obesity - overweight is having extra body weight from muscle, bone, fat, and/or water - obesity is having a high amount of extra body fat. Myocardial infarction also known as Heart attack is a medical condition that occurs when blood stops flowing properly to a part of the heart Usually this is because one of the coronary arteries that supplies blood to the heart develops a blockage due to an unstable buildup of white blood cells, cholesterol and fat. c. Unstable plaques can release their lipid content into the blood stream. THROMBOSIS, EMBOLISM AND INFARCTION 2. — A primary pulmonary artery sarcoma is an uncommon cause of an intraluminal arterial filling defect. Background: The prognostic significance of venous tumor thrombus extension in patients with renal cell carcinoma (RCC) is a matter of many controversies in the current literature. Atherosclerosis, chronic disease caused by the deposition of fats, cholesterol, calcium, and other substances in the innermost layer of endothelium of the large and medium-sized arteries. MANAGEMENT OF THROMBUS BURDEN DURING PAMI. Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising. You can change your ad preferences anytime. Atherosclerosis is the most common arterial However, there are other types of emboli air, fat, amniotic fluid, and septic (from bacterial invasion of the thrombus). Lipids are fats that are either absorbed from food or synthesized by the liver. The thrombus formed at the rupture site is called white thrombus due to its grossly white appearance of rich platelet. An unstable plaque has thicker arterial walls, which restricts blood flow. [2][3] • After initial injury, there is a brief period of arteriolar vasoconstriction, largely attributable to reflex neurogenic mechanisms and augmented by the local secretion of factors such as endothelin (a potent endothelium-derived vasoconstrictor). J It includes deep vein thrombosis and pulmonary thrombosis. Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising. Normal Haemostasis Process of maintaining blood in a fluid, clot – free state in normal vasculature and rapidly forming a localized haemostatic plug at the site of vascular injury The pathologic opposite of haemostasis is thrombosis Usually you will get medicine to put you to sleep for this procedure. causing the formation of a thrombus that will rapidly slow or stop blood flow, leading to death of the tissues fed by the artery in approximately 5 minutes. b. Clipping is a handy way to collect important slides you want to go back to later. The embolus may be a blood clot , a fat globule (fat embolism), a bubble of air or other gas (gas embolism), amniotic ... Thrombus formation can also take place within the ventricles, and it occurs in approximately 30% of anterior-wall myocardial infarctions, compared with only 5% of inferior ones. Final thrombus burden 1. These tumors should be surgically excised when symptomatic [4]. Hemodynamic Disorders 2. Dietary cholesterol esters are de-esterified into free cholesterol by these same mechanisms. This catastrophic event is called an infarction. Clipping is a handy way to collect important slides you want to go back to later. Although the embolus can be a blood clot (thrombus), fat, air, amniotic fluid, or tumour, a PE is usually caused by a thrombus originating from the deep veins in the legs (deep venous thrombosis, DVT). Statins 1. Thrombus formation after plaque disruption can lead to acute coronary syndrome 1,2. The criteria for in situ thrombus include (a) thrombus at the surgical site only (, Fig 36) and (b) the absence of other pulmonary artery thrombi remote from the stump site (, 37). Scalp Fat ~ -84.5 HU Air ~ -966.3 HU Tissue Density Differences Lower density substances allow more photons pass through to the detectors, resulting in a grayer or blacker appearance on … Your health care provider can insert a tool in the tube to break up the clot or to deliver medicine through the tube. Wall of affected bowel is thickened with low- density center representing submucosal edema. Arteries are blood vessels that carry blood from the heart to the rest of the body and the heart muscle.

Blood PES Modern College of Pharmacy (For Ladies), Moshi, Pune Ms. Rohini R. Pujari In patients with RCC and VTT, the presence of a friable thrombus is an independent predictor of CSS. In these cases, pre-mortem clots may simply be mixed in with atherosclerotic plaque. Pulmonary embolism ppt 1. a thrombus (or thrombi) that originates somewhere in the venous system or in the right side of the heart. If our finding is confirmed by further studies, the consistency of the tumour thrombus should be introduced into routine pathologic reports to provide better patient risk stratification. Natural History If thrombus forms inside blood vessel, then possible outcomes: Embolisation Lysis Ischaemia Organisation 8. When Thrombus leads to quick death \(i.e. Peripheral arterial disease is a term used to describe a wide variety of conditions affecting arteries in the neck, abdomen and extremities. artery or one of its branches by material (eg, thrombus, tumor, air, or fat) that originated elsewhere in the body.
