1. Thromboembolism: A blood clot forms elsewhere in the body and travels through the bloodstream to block a blood vessel in the lower extremity, causing ischemia.
2. Atherosclerosis: Narrowing or blocking of the arteries due to the buildup of plaque, leading to reduced blood flow to the lower extremity.
3. Arterial embolism: A piece of plaque or blood clot breaks off from an artery and becomes lodged in a smaller artery in the lower extremity, causing ischemia.
4. Arterial dissection: A tear in the inner lining of an artery can lead to the formation of a blood clot, which can block blood flow and cause ischemia.
5. Vasculitis: Inflammation of blood vessels can restrict blood flow to the lower extremity, leading to ischemia.
6. Trauma: Injury to the lower extremity can disrupt blood flow and cause acute ischemia.
7. Compartment syndrome: Increased pressure within a muscle compartment due to swelling or bleeding can reduce blood flow and lead to ischemia.
