CPT® Code 35522

An axillary-brachial bypass graft is a surgical procedure designed to create a new pathway for blood flow around a diseased or obstructed segment of the axillary and brachial arteries, which are located on the same side of the body. This procedure is typically indicated when there is significant blockage that impairs blood circulation, potentially leading to complications such as ischemia or limb loss. The surgery involves making incisions in the chest and arm to access the affected arteries. A vein, often harvested from the leg, is used as a graft to bypass the obstructed area. The procedure requires careful dissection of soft tissues to expose the arteries, creating a tunnel for the graft, and ensuring that the graft is securely attached to both the axillary and brachial arteries. The use of vascular clamps during the procedure helps to control blood flow, allowing for a safer and more effective grafting process. Post-surgery, the success of the graft is monitored through Doppler ultrasound to assess blood flow and ensure that the bypass is functioning properly.
