CPT® Code 35671

A bypass graft using other than vein is a surgical procedure performed on the arteries of the lower extremity, specifically targeting the popliteal-tibial or peroneal arteries. This procedure is indicated when there is a need to restore blood flow to the lower leg due to blockages or narrowing of the arteries that can lead to ischemia or other complications. The surgery involves creating a new pathway for blood to flow, bypassing the obstructed segment of the artery. In this case, the procedure is performed through an incision made behind the knee, allowing access to the popliteal artery. The distal anastomosis site is also prepared, which may involve the anterior tibial, posterior tibial, or peroneal arteries. A synthetic graft is utilized instead of a vein, which is selected based on the size required for the grafting. The graft is then surgically attached to both the proximal and distal ends of the artery, ensuring that blood can flow freely through the newly created bypass. This procedure is critical for patients suffering from peripheral artery disease or other vascular conditions that compromise blood circulation in the lower extremities.
