Adventitial Cystic Disease

Adventitial cystic disease is a rare disease that occurs when a cyst filled with a mucus-like substance forms in one of the arteries, most commonly in the popliteal artery, which supplies blood to the knee joint and thigh and calf muscles. The cyst causes the affected artery to become blocked or narrowed. Surgery is the most common approach to treating adventitial cystic disease. Learn more about treatments at UVA.
