Arterial thrombosis is a blood clot in an artery, which can be very serious because it can stop blood reaching important organs. When severe enough it can cause angina or an acute coronary syndrome including myocardial infarction. 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. Dietary TGs are digested in the stomach and duodenum into monoglycerides (MGs) and FFAs by gastric lipase, emulsification from vigorous stomach peristalsis, and pancreatic lipase. Although generally better than CHESS/Fat-Sat sequences, modern Dixon methods still have their limitations, particularly in highly inhomogeneous areas like the neck and around metal hardware. Thrombotic strokes are further divided into two categories based on the size of the area of blockage within the brain: large-vessel thrombosis and small-vessel thrombosis.

Fibroblasts eventually invade the thrombus, scarring vein wall and destroying valves. 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 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. Thrombus • Most common intra-cardiac mass • Location often associated with cardiac pathology –LV thrombus •Acute MI –Estimated 4-15% patients with anterior MI (LV apex) •Dilated cardiomyopathy –DDx: false b. Pieces of thrombus may break loose and travel through circulation- emboli. The blood clot may block the flow of oxygen-rich blood to a portion of the brain, causing long-term brain damage.This type of brain damage caused by a lack of adequate blood supply produces a stroke. 6 hemodynamic disorders 1.

In patients with RCC and VTT, the presence of a friable thrombus is an independent predictor of CSS. Embolism, obstruction of the flow of blood by an embolus, a particle or aggregate of substance that is abnormally present in the bloodstream. At the proximal and distal ends near the site of white thrombosis there is another type of thrombus composed of layers of red blood cells and fibrin and is therefore called red thrombus. c. Unstable plaques can release their lipid content into the blood stream. 24.
