Retrograde type A aortic dissection after thoracoabdominal aneurysm repair: early diagnosis with intraoperative transesophageal echocardiography

A & a Case Reports
Shobana RajanShiva Sale

Abstract

Retrograde type A aortic dissection that arises immediately after open replacement of the thoracoabdominal aorta is a rare and potentially lethal complication that has only been reported twice previously. A 74-year-old man with a history of expanding Crawford type I thoracoabdominal aortic aneurysm presented for open surgical repair. The intraoperative course was unremarkable. However, intraoperative transesophageal echocardiography after the repair revealed type A aortic dissection extending up to the sinotubular junction. Subsequently, emergent aortic arch repair was performed under deep hypothermic circulatory arrest. Early diagnosis with transesophageal echocardiography and optimal cerebral protection were instrumental in the successful outcome of this repair.

Aortic Aneurysm

An aortic aneurysm is the weakening and bulging of the blood vessel wall in the aorta. This causes dilatation of the aorta, which is usually asymptomatic but carries the risk of rupture and hemorrhage. Find the latest research on aortic aneurysms here.
