Intraoperative angiography for visceral arteries originating from false lumen

Abstract

A 70-year-old man had an acute type B aortic dissection 9 years before his admission. The last enhanced computed tomography that was performed revealed an aneurysm that extended from the ascending aorta to the aortic arch, associated with a chronic aortic dissection, which extended from the aortic arch to the left external iliac artery. His visceral arteries originated from the false lumen. We performed a total arch replacement with a frozen elephant trunk in the hybrid operating room. Immediately after the circulatory arrest termination, using intraoperative angiography, we verified that the blood supply to the visceral arteries was patent.
