Common Language Description

The CPT® Code 33859 refers to a surgical procedure involving the repair of the ascending aorta using a graft, which is performed with the assistance of cardiopulmonary bypass. This procedure is specifically indicated for patients suffering from aortic disease, excluding dissection, such as an aortic aneurysm. The ascending aorta is a critical part of the heart's anatomy, responsible for carrying oxygenated blood from the heart to the rest of the body. In cases where the aorta is weakened or dilated, as seen in aneurysms, surgical intervention is necessary to prevent life-threatening complications. The procedure typically involves a median sternotomy, which is an incision made along the sternum to provide access to the heart and aorta. During the operation, cardiopulmonary bypass is initiated to take over the function of the heart and lungs, allowing the surgeon to operate on a still and bloodless field. The procedure may also include valve suspension if deemed necessary, ensuring that the aortic valve functions properly post-surgery. This comprehensive approach aims to restore normal blood flow and prevent further complications associated with aortic disease.
