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.
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 ]
The dense MCA sign is caused by a fresh thrombus or embolus occluding the lumen of the middle cerebral artery. A thrombus with a high concentration of red blood cells and fibrin has increased density relative to normal flowing blood, leading to its hyperattenuating appearance on a non-contrast CT scan.
Acute thrombus in the right MCA M1 branch. A stroke is the rapid decline of brain function due to a disturbance in the supply of blood to the brain. [13] This can be due to ischemia, thrombus, embolus (a lodged particle) or hemorrhage (a bleed). [13] In thrombotic stroke, a thrombus (blood clot) usually forms around atherosclerotic plaques ...
Infarction occurs as a result of prolonged ischemia, which is the insufficient supply of oxygen and nutrition to an area of tissue due to a disruption in blood supply.The blood vessel supplying the affected area of tissue may be blocked due to an obstruction in the vessel (e.g., an arterial embolus, thrombus, or atherosclerotic plaque), compressed by something outside of the vessel causing it ...
Coronary thrombosis is defined as the formation of a blood clot inside a blood vessel of the heart. This blood clot may then restrict blood flow within the heart, leading to heart tissue damage, or a myocardial infarction, also known as a heart attack.
Higher intraluminal pressure in patients with arterial hypertension markedly contributes to the progression of the pathological process. [18] Suitable hemodynamic conditions may be linked to specific intraluminal thrombus (ILT) patterns along the aortic lumen, which in turn may affect AAA's development.
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]
