CPT® Code 33335

The procedure described by CPT® Code 33335 involves the insertion of a graft into the aorta or great vessels, utilizing cardiopulmonary bypass. This surgical intervention is typically indicated in cases of injury to the aorta or great vessels, which may arise from either blunt or penetrating trauma. Such injuries can lead to severe complications, including transection, rupture, tear, or laceration of these critical blood vessels. The use of a synthetic graft is essential for repairing these injuries, as it provides structural support and restores blood flow. The procedure can be performed using two techniques: one that does not require cardiopulmonary bypass, known as the clamp and sew technique (CPT® Code 33330), and the one that does, which is the focus of this code. During the operation, a thoracotomy is performed to access the injured vessels, and careful dissection is carried out to expose the aorta and surrounding structures. The surgical team must take meticulous steps to control bleeding and ensure the integrity of the repair, which involves creating anastomoses between the graft and the aorta or great vessels. This complex procedure is critical for managing life-threatening vascular injuries and restoring hemodynamic stability in affected patients.
