CPT® Code 33330

The procedure described by CPT® Code 33330 involves the insertion of a synthetic graft into the aorta or great vessels to repair injuries that may arise from either blunt or penetrating trauma. Such injuries can lead to serious conditions, including transection, rupture, tear, or laceration of the aorta or great vessels. This surgical intervention is critical for restoring blood flow and preventing life-threatening complications. The procedure is performed without the use of a shunt or cardiopulmonary bypass, which is often referred to as the clamp and sew technique. This approach allows the surgeon to directly access and repair the damaged vessels while minimizing the need for additional support systems that can complicate the procedure. The operation typically requires a thoracotomy, which is an incision into the chest to expose the injured blood vessels. The surgical team carefully identifies and protects surrounding structures, such as the phrenic nerves and adjacent arteries, to ensure a successful repair. The use of synthetic grafts is essential in providing a durable solution to the injury, allowing for the restoration of normal vascular function.
