CPT® Code 33332

Deleted

The procedure described by CPT® Code 33332 involves the insertion of a graft into the aorta or great vessels, specifically utilizing a shunt bypass technique. This surgical intervention is typically indicated in cases of injury to the aorta or great vessels, which can arise from either blunt or penetrating trauma. Such injuries may manifest as transections, ruptures, tears, or lacerations of the aorta or great vessels, necessitating prompt and effective repair to restore vascular integrity and ensure adequate blood flow. The use of a synthetic graft is crucial in these scenarios, as it provides a durable solution to replace or repair the damaged vessel. The shunt bypass method allows for continued blood perfusion to distal arteries during the surgical procedure, which is essential for maintaining organ function and preventing ischemia. This technique involves cannulation of the left ventricular apex, ascending aorta, or left subclavian artery, facilitating blood flow while the surgical repair is being performed. The procedure is complex and requires careful dissection and exposure of the injured vessels, ensuring that all anatomical structures are preserved and protected throughout the operation.
