Abstract

A 49-year-old man was admitted to our department 6 months after emergent surgery for type-A acute aortic dissection. A chest computed tomography-scan revealed a huge aneurysm originating from the proximal aortic arch, strongly adherent to the upper part of the sternum. Extracorporeal circulation was instituted first, and chest was reopened in circulatory arrest. The mass was a giant pseudoaneurysm originating from a laceration at the base of the innominate artery. Due to tissue fragility and complete distortion of the origin of right carotid and subclavian arteries, we performed an extra-anatomic ascending aorta-to-right carotid artery bypass, followed by Teflon-reinforced suture of the proximal artery stumps. The postoperative course was uneventful.
