Popliteal artery bypass is a surgical procedure designed to bypass blocked or narrowed popliteal arteries, which are located behind the knee. This procedure is commonly used for patients with peripheral artery disease (PAD) that affects the lower leg. During the surgery, a graft is used to reroute blood flow around the blockage, improving circulation to the foot and lower leg.

Popliteal artery bypass is effective for alleviating symptoms such as leg pain, numbness, or sores, and preventing tissue damage or amputation.
