CPT® Code 35656

The procedure described by CPT® Code 35656 involves a bypass graft using a synthetic material rather than a vein, specifically targeting the femoral to popliteal artery region. This surgical intervention is typically indicated for patients with significant arterial occlusion or blockage that impairs blood flow to the lower extremities. The procedure begins with a surgical incision in the groin area to access the femoral artery, which is a major blood vessel supplying blood to the leg. Simultaneously, an incision is made behind the knee to expose the popliteal artery, which is located at the back of the knee joint. A tunnel is then created between these two arteries to facilitate the placement of a synthetic graft. The graft is carefully selected based on the size required for optimal fit and is prepared for implantation. The surgical team clamps the femoral artery to prevent blood flow during the anastomosis process, where the graft is surgically connected to both the femoral and popliteal arteries. After the graft is secured, vascular clamps are released, and the blood flow is assessed to ensure that the graft is functioning properly. This procedure is critical for restoring adequate blood circulation to the lower leg and preventing complications associated with poor blood flow, such as pain, ulcers, or limb loss.
