Transcatheter embolization of a type II endoleak after hybrid repair for thoracoabdominal aortic aneurysm.

Hybrid stent-graft procedures with visceral revascularization have been reported as an alternative treatment option for thoracoabdominal aortic aneurysms (TAAAs), although the potential advantages of reduced morbidity and mortality compared with open surgical repair have not been definitively demonstrated. Endovascular aneurysm repair is associated with endoleaks in as many as 20% of cases in some series, often requiring repeat intervention. In the present case, during follow-up after a hybrid TAAA repair, a patient developed a type II endoleak originating from a celiac artery that was not ligated at its origin. The endoleak was successfully treated by transcatheter coil embolization.
