CPT® Code 35231

The procedure described by CPT® Code 35231 involves the surgical repair of a blood vessel located in the neck using a vein graft. This procedure is typically indicated when there is an injury to a blood vessel in the neck, which may result from trauma, disease, or other medical conditions. The approach taken during the surgery is contingent upon the specific blood vessel that has sustained damage. Initially, the injured blood vessel is accessed surgically, and clamps are applied both proximal and distal to the site of injury. This clamping is essential to control any bleeding that may occur during the procedure. In some cases, to maintain blood flow while the repair is being performed, a temporary shunt may be placed. Once the area is adequately prepared, the extent of the injury is carefully assessed. A segment of vein, often harvested from the saphenous vein located in the lower leg, is then prepared for use as a graft. The edges of the damaged blood vessel are debrided to ensure a clean surface for the grafting process. The prepared vein graft is meticulously sewn to both the proximal and distal ends of the injured blood vessel, effectively bridging the gap created by the injury. After the graft is secured, the temporary shunt is removed, and the clamps are released. At this stage, the surgeon checks for hemostasis, ensuring that there is no bleeding along the suture line. Finally, the overlying tissues are repaired in layers with sutures, completing the procedure and restoring the integrity of the blood vessel in the neck.
