Stent-Graft Treatment of Thoracoabdominal Aortic Aneurysms after Complete Visceral Debranching

Complex thoracoabdominal aortic aneurysm repair remains a difficult problem from both open and endoluminal approaches. The reduced morbidity and mortality rates reported to be associated with aortic stent-graft procedures makes this option more attractive, but it is hampered by the need for adequate proximal and distal seal zones. While branched and fenestrated aortic stent-grafts are being refined, an alternative is a two-stage surgical and endoluminal approach that is particularly useful for aneurysms involving the aortic visceral segment. The present report describes stent-graft repair in two patients after complete visceral artery revascularization or “debranching.”
