CPT® Code 35666

A bypass graft using other than vein is a surgical procedure performed on the arteries of the lower extremities, specifically targeting the femoral-anterior tibial, posterior tibial, or peroneal arteries. This procedure is indicated when there is a need to restore blood flow to the lower leg due to arterial blockages or other vascular issues. The surgery involves creating a new pathway for blood to flow, bypassing the obstructed or diseased segment of the artery. The operation begins with a groin incision on the affected side to expose the femoral artery, which is a major blood vessel supplying the leg. The surgeon then identifies the distal anastomosis site on the anterior tibial, posterior tibial, or peroneal artery, which will receive the graft. The use of a synthetic graft, rather than a vein, is crucial in this procedure, as it provides a durable and effective means of restoring circulation. The surgical technique includes careful anastomosis of the graft to both the proximal and distal arteries, ensuring that blood flow is reestablished effectively. Post-surgery, the patency of the graft is confirmed through Doppler ultrasound and evaluation of distal pulses, ensuring that the bypass is functioning as intended.
