CPT® Code 35363

Thromboendarterectomy is a surgical procedure aimed at removing thrombi, which are blood clots or atherosclerotic plaques, from occluded arteries. Specifically, CPT® Code 35363 refers to a combined aortoiliofemoral thromboendarterectomy, which involves the abdominal aorta, iliac artery, and femoral artery. This procedure is essential for restoring blood flow in patients with significant arterial blockages that can lead to severe complications, including ischemia or limb loss. The process begins with an incision in the abdomen to access the aorta and iliac arteries, and if necessary, an additional incision in the leg to access the femoral artery. The surgeon isolates the affected segments of the blood vessels, carefully dissects them from surrounding tissues, and removes the obstructive material along with the inner lining of the artery (intima) to enhance the vessel's diameter. This meticulous approach not only alleviates the blockage but also aims to restore normal blood flow, thereby improving the patient's overall vascular health. The procedure may involve the use of temporary shunts to maintain perfusion during surgery and may conclude with the application of sutures or grafts to repair the arteries, ensuring that blood flow is reestablished effectively.
