What medical term means loss of bloof supply from occlusion?
The medical term for the loss of blood supply due to occlusion is "ischemia." Ischemia occurs when blood flow is restricted or blocked, often leading to tissue damage or dysfunction. This can result from various causes, including thrombosis or embolism, and is critical in conditions like heart attacks and strokes.
What is renal artery occlusion?
Renal artery occlusion is a blockage of the major arteries that supply blood to the kidneys caused by thrombosis or embolism.
Is retinal vein occlusion related to root canal work?
Retinal Vein OcclusionThe central retinal vein is the venous equivalent of the central retinal artery, and like that blood vessel can suffer from occlusion (central retinal vein occlusion), similar to that seen in ocular ischemic syndrome. Since the central retinal artery and vein are the sole source of blood supply and drainage for the retina, such occlusion can lead to severe damage to the retina and blindness, due to ischemia (restriction in blood supply) and edema (swelling). It can also cause glaucoma.
What do you call the death of tissue associated with the loss of blood supply?
The death of tissue associated with the loss of blood supply is called "necrosis." This condition occurs when cells do not receive sufficient oxygen and nutrients due to disrupted blood flow, leading to cell injury and eventual death. It can result from various factors, including trauma, infection, or vascular occlusion. Common types of necrosis include coagulative, liquefactive, and caseous necrosis, each with distinct characteristics.
What does Coronary occlusion mean?
Coronary occlusion refers to the blockage of one or more coronary arteries, which supply blood to the heart muscle. This blockage can be caused by a buildup of plaque (atherosclerosis), blood clots, or spasms in the arteries. Coronary occlusion can lead to reduced blood flow to the heart, resulting in chest pain (angina) or a heart attack (myocardial infarction) if not treated promptly. Timely medical intervention is crucial to restore blood flow and minimize damage to the heart.
What is an occlusion?
a closure or blockage of a blood vessel.
What is thrombotic occlusion?
A thrombotic occlusion is when a blot clot is formed in a blood vessel that stops most or all blood flow, and causes localized ischemia.
What is the most common symptom of retinal artery occlusion?
The most common symptom of RAO is an acute, painless loss of vision in one eye. The degree of loss depends on the location of the occlusion.
Deficient blood supply to the myocardium is?
Deficient blood supply to the myocardium is: ischemia Ischemia is the medical terms for deficient blood supply to the myocardium. The suffix -emia denotes a blood condition; ischem/o means to hold back. With occlusion from atherosclerosis, the blood flow is restricted, resulting in deficient blood supply.
What is the medical term meaning death of brain tissue from loss of blood supply?
Avascular is the medical term meaning without blood vessels.
What is a retinal artery occlusion?
Retinal artery occlusion refers to the closure of the central retinal artery and usually results in complete loss of vision in one eye.
How does reactive hyperemia work?
Decreased tissue blood flow due to occlusion will result in metabolic vasodilators accumulating in the extracellular fluid. The arterioles will hence dilate but the occlusion will still prevent normal blood flow. The occlusion is then removed and decreased resistance will increase blood flow. As the vasodilators are washed away, the arterioles constrict, and the blood flow returns to normal.
