Renal Artery Occlusion
Definition
Renal artery occlusion is a blockage of the major arteries that supply blood to the kidneys caused by thrombosis or embolism.
Description
Renal artery occlusion occurs when the flow of blood from the arteries leading to the kidneys becomes blocked by a blood clot or cholesterol emboli. The lack of oxygenation can lead to necrosis (tissue death) and ultimately, chronic kidney failure.
