Arch Surgery for Type Ia Endoleak: How to Remain Normothermic and Avoid Circulatory Arrest.

Abstract

Type Ia endoleak after thoracic endovascular aortic repair is an ominous complication that requires an aggressive treatment. Total arch replacement with a distal suture taking the native distal aorta, the stent graft, and the arch graft, by allowing a perfect closure of the proximal endoleak, represents the most common treatment in this setting. Nevertheless, such intervention continues to carry significant mortality and morbidity that are mostly related to prolonged extracorporeal circulation time and hypothermic circulatory arrest. Here, we present a technique for total arch replacement that, with the use of stent graft balloon endoclamping, avoids both hypothermia and circulatory arrest.
