Use of a surgeon-modified branched thoracic endograft to preserve an aortorenal bypass during treatment of an intercostal patch aneurysm.

摘要

A 72-year-old man presented with thoracic pain. Nine years earlier, a descending aortic dissection with aneurysmal degeneration had been treated by thoracoabdominal aortic graft placement with reimplantation of a visceral patch and an intercostal patch. A separate left aortorenal bypass had also been performed with the bypass originating from the thoracic portion of the graft. He now presents with a 7.2-cm intercostal patch aneurysm in the aortic segment containing the origin of the patent aortorenal bypass. We present the use of a surgeon-modified branched thoracic endograft to salvage an aortorenal bypass originating in a thoracic aneurysm after previous open thoracoabdominal aortic aneurysm repair.
