Left ventricular thrombus is a blood clot in the left ventricle of the heart. LVT is a common complication of acute myocardial infarction (AMI). [ 1 ] [ 2 ] Typically the clot is a mural thrombus, meaning it is on the wall of the ventricle. [ 3 ]
Acute aortic syndrome (AAS) describes a range of severe, painful, potentially life-threatening abnormalities of the aorta. [1] These include aortic dissection, intramural thrombus, and penetrating atherosclerotic aortic ulcer. [2] AAS can be caused by a lesion on the wall of the aorta that involves the tunica media, often in the descending ...
A thrombus (pl. thrombi), colloquially called a blood clot, is the final product of the blood coagulation step in hemostasis. There are two components to a thrombus: aggregated platelets and red blood cells that form a plug, and a mesh of cross-linked fibrin protein. The substance making up a thrombus is sometimes called cruor.
An aortic aneurysm often doesn’t cause symptoms, but it can lead to severe, sudden bleeding from a ruptured aneurysm. A ruptured aneurysm has a high risk of death. If symptoms of an aortic ...
Lines of Zahn can be used to confirm diagnosis of a thrombus. [1] Their presence implies thrombosis at a site of rapid blood flow that happened before death. They are more common in thrombi formed in the heart or aorta. [5] In veins or smaller arteries, where flow is not as constant, they occur less frequently. [5]
A thrombus, or a blood clot, is a mobilized mass of blood cells that circulates within the body. [21] [22] Thrombi can occlude veins (venous thrombosis) or arteries (arterial thrombosis). The etiology of thrombosis is described by Virchow's Triad, which includes hemostasis, vascular wall damage, and hypercoagulability. [21]
The hyperdense area is due to intramural or mural thrombus haemorrhage. The blood that dissects through mural thrombosis or wall of the aneurysm causes weakening of the wall. [4] This is of relatively high density compared to the psoas muscle in contrast-enhanced CT and greater than the aorta in non-contrast CT imaging. [5]
ATE is usually caused by atherosclerosis, which leads to plaque rupture and thrombus formation, or by cardioembolism, which results from the embolization of a cardiac thrombus, such as in atrial fibrillation, valvular disease, or myocardial dysfunction. The management of ATE depends on the location and severity of the ischemia and the ...
