Surgical treatment for cervical aortic arch with aneurysm formation.

Cervical aortic arch is an unusual malformation. Cervical aortic arch with aneurysm formation is very rare. We report a case of cervical aortic arch associated with a saccular aneurysm in a 59-year-old Japanese man. The aneurysm protruded caudally and was located between the left common carotid and left subclavian arteries. Cardiopulmonary bypass and deep hypothermic circulatory arrest was applied as adjunct methods. A Dacron graft was sutured just distal to the left common carotid artery, with the patient in the Trendelenburg position. The proximal site was left open while oxygen-saturated venous blood was supplied in a retrograde manner to perfuse the lower body during occlusion of the descending aorta. Distal anastomosis to the descending aorta was performed during rewarming. The left subclavian artery was reconstructed by using a branch of the graft. This procedure is simple and useful for distal arch operations, especially in patients with Haughton D type aneurysms.
