The fourth and last representation of PAD, a dangerous condition which when takes place, the blood flow to the legs are suddenly stopped. Unlike chronic conditions such as peripheral artery diseases, which develop gradually, ALI comes on quickly, often within hours or days. The sudden reduction in blood flow can cause severe pain, tissue damage, and, if not treated promptly, permanent disability or amputation.
Causes of acute limb ischemia:
Blood clots (thrombosis): A clot forming in an already narrowed artery can suddenly block blood flow.
Embolism: A clot or debris from the heart or another part of the body travels through the bloodstream and lodges in a limb artery. This is common in people with atrial fibrillation.
Trauma: Severe injury to a limb can damage blood vessels and interrupt circulation.
Vascular surgery complications: Rarely, surgery or medical procedures can accidentally lead to blocked arteries.
