Hybrid endovascular exclusion of a bleeding innominate artery pseudoaneurysm in a patient with no open surgical options

摘要

Mycotic pseudoaneurysms (MPs) rarely affect the aortic arch vessels and usually require surgical resection for definitive treatment. In this case, a 58-year-old woman developed a bleeding innominate artery MP after primary lung cancer resection complicated by an infected chest wound. Because of her previous surgery, irradiation, and chest wall reconstruction, she was not a candidate for open resection. A hybrid endovascular approach successfully excluded her innominate artery MP through placement of an aortic arch stent graft. Cerebral circulation was maintained through a periscoped left common carotid artery stent graft to the descending thoracic aorta graft, which supplied a left-to-right carotid-carotid bypass.
