CPT® Code 33320

The procedure described by CPT® Code 33320 involves the suture repair of the aorta or great vessels, specifically performed without the use of a shunt or cardiopulmonary bypass. This surgical intervention is critical in addressing injuries to the aorta or great vessels, which can arise from various forms of trauma, including both blunt and penetrating injuries. Such injuries may lead to severe complications, including transection, rupture, tear, or laceration of the aorta or great vessels, necessitating immediate surgical repair to restore vascular integrity and prevent life-threatening hemorrhage. The technique employed in this procedure is often referred to as the "clamp and sew" method, which allows for direct repair of the injured vessel while maintaining some degree of blood flow. The procedure requires a thoracotomy to access the affected vessels, and meticulous dissection is performed to expose the injury site. The repair process involves careful suturing of the damaged area to ensure proper healing and restoration of normal blood flow. This procedure is essential for patients who have sustained significant vascular injuries and is performed under strict surgical protocols to minimize complications and optimize patient outcomes.
