Endovascular Treatment of Aortic Dissection due to Suture Line Dehiscence after Aortic Graft Replacement for Type A Aortic Dissection: A Report of Two Cases

Abstract

Aortic anastomotic leak is an uncommon complication after ascending aortic replacement for acute aortic dissection. Redo-surgery is the traditional standard treatment despite high mortality and morbidity. Recently, endovascular treatment has been attempted as an alternative approach in a few case reports. Here, we present two cases of aortic anastomotic leak due to suture line dehiscence after aortic graft replacement for type A aortic dissection, which were successfully treated by coil with subsequent N-butyl cyanoacrylate embolization and an Amplatzer™ vascular plug.
