Arterial occlusion is a condition involving partial or complete blockage of blood flow through an artery. Arteries are blood vessels that carry oxygenated blood to body tissues. [ 1 ] [ 2 ] An occlusion of arteries disrupts oxygen and blood supply to tissues, leading to ischemia . [ 1 ]
Left atrial appendage occlusion (LAAO), also referred to as left atrial appendage closure (LAAC), is a procedure used to reduce the risk of blood clots from the left atrial appendage entering the bloodstream and causing a stroke in those with non-valvular atrial fibrillation.
Cherry red spot in a person with central retinal artery occlusion. Central retinal artery occlusion is characterized by painless, acute vision loss in one eye. [1] Upon fundoscopic exam, one would expect to find: cherry-red spot (90%) (a morphologic description in which the normally red background of the choroid is sharply outlined by the swollen opaque retina in the central retina), retinal ...
Ocular ischemic syndrome is the constellation of ocular signs and symptoms secondary to severe, chronic arterial hypoperfusion to the eye. [1] Amaurosis fugax is a form of acute vision loss caused by reduced blood flow to the eye; it may be a warning sign of an impending stroke, as both stroke and retinal artery occlusion can be caused by thromboembolism due to atherosclerosis elsewhere in the ...
Peripheral artery disease (PAD) is a form of peripheral vascular disease. Vascular refers to both the arteries and veins within the body. PAD differs from peripheral veinous disease. PAD means the arteries are narrowed or blocked—the vessels that carry oxygen-rich blood as it moves away from the heart to other parts of the body.
Embolization involves the selective occlusion of blood vessels by purposely introducing emboli, in other words deliberately blocking a blood vessel. Embolization is used to treat a wide variety of conditions affecting different organs of the human body. Embolization is commonly used to treat active arterial bleeding.
Anterior cerebral artery syndrome is a condition whereby the blood supply from the anterior cerebral artery (ACA) is restricted, leading to a reduction of the function of the portions of the brain supplied by that vessel: the medial aspects of the frontal and parietal lobes, basal ganglia, anterior fornix and anterior corpus callosum.
Another technique is digital subtraction angiography which allows verification of the diagnosis and endovascular treatment in a single session. [2] Angiography provides important information regarding the perfusion and patency of distal arteries (e.g. femoral artery). The presence of collateral arteries in the pelvic and groin area is important ...
