The popliteal artery is a crucial blood vessel located behind the knee, responsible for supplying blood to the lower leg and foot. Cholesterol embolism, a condition where cholesterol particles block small blood vessels, can affect the popliteal artery, leading to various complications. In this guide, we’ll break down the types, causes, symptoms, diagnostic tests, treatments, drugs, and surgical options associated with popliteal artery cholesterol embolism in easy-to-understand language.
Types of Popliteal Artery Cholesterol Embolism:
There are two main types:
- Complete Blockage (Total Occlusion):
- Cholesterol particles completely block the popliteal artery, disrupting blood flow to the lower leg and foot.
- Partial Blockage (Partial Occlusion):
- Cholesterol particles partially obstruct the artery, causing reduced blood flow and potential complications.
Common Causes of Popliteal Artery Cholesterol Embolism:
- Atherosclerosis:
- Buildup of cholesterol plaques in the arteries.
