title: Surgical treatment of ruptured aneurysms of the innominate artery.
abstract: The cases of 3 patients with an aneurysm of the innominate artery treated surgically are reported. The clinical manifestations were different, and the surgical procedures employed also varied. In 1 patient, the neck of the aneurysm was isolated and clamped near the aortic arch. It was closed, and a graft was interposed between the ascending aorta and the right carotid and subclavian arteries. In the second, the aneurysm was resected under cardiopulmonary bypass, deep hypothermia, and total circulatory arrest. The neck was closed with a large Teflon patch, and a tube graft was interposed between the ascending aorta and the right carotid artery. In the third, a graft was interposed between both carotid arteries; conventional cardiopulmonary bypass was instituted, and the aorta was clamped between the innominate and the left carotid arteries. The neck of the aneurysm was closed, and a graft was interposed between the ascending aorta and the right carotid and subclavian arteries. All patients had an excellent postoperative course. Our comments regarding the clinical and surgical aspects of this condition are based on the present experience and reports in the literature.
