Pseudoaneurysms of the sovra-aortic trunks are uncommon lesions that usually have a post-traumatic etiology. The singular case of a patient who developed an innominate artery pseudoaneurysm (IAP) where a stent had been inserted 12 years earlier to manage severe innominate trunk stenosis is described. A chronic and large (8 cm in diameter) IAP was successfully treated in extracorporeal circulation and deep hypothermic circulatory arrest. The distal tract of the ascending aorta and the proximal aortic arch were substituted; total replacement of the innominate trunk with a singular 8-mm Dacron graft was necessary. We reviewed the literature about the reports of IAPs and the management of this singular lesion.
