CPT® Code 35663

An ilioiliac bypass graft is a surgical procedure that involves creating a new pathway for blood flow between the iliac arteries, which are major blood vessels located in the pelvis. This procedure is performed using a graft that is not derived from the patient's own veins, typically utilizing a synthetic material instead. The surgery begins with an incision in the abdomen to access the iliac arteries, allowing the surgeon to carefully expose and dissect these arteries from the surrounding tissues. The goal of the bypass graft is to restore adequate blood flow to the lower extremities, which may be compromised due to blockages or other vascular issues. During the procedure, a tunnel is created to facilitate the placement of a cross-over graft that connects the two iliac arteries. The graft is meticulously sutured to the arteries, and the surgical team ensures that blood flow is restored and that there are no leaks at the suture sites. The use of Doppler ultrasound is critical in this process, as it allows for the assessment of blood flow through the graft and the evaluation of distal pulses to confirm the success of the bypass. This procedure is essential for patients who require improved circulation to their legs and lower body, particularly in cases where traditional vein grafts are not suitable.
