Complications

Long-term pressure on the popliteal artery can cause the artery to narrow (stenosis), causing pain and cramping with just slight activity, such as walking.

In severe cases or when undiagnosed, the nerves and muscles in the leg can become damaged. Blood clots may occur in the lower leg (deep vein thrombosis). Older athletes with signs and symptoms of popliteal artery entrapment syndrome should be checked for popliteal aneurysm, which is common in older men.
