The early results show that emergent endovascular treatment of hemodynamically stable and unstable patients is associated with a limited mortality of 18% once a standardized protocol is established. There is an increased recognition of emerging complications with an endovascular approach, and a synchrony of disciplines must be developed to initiate a successful program for endovascular treatment of r-AAAs.

Mortality for females undergoing elective EVAR is significantly greater than for males. It is also more hazardous. Colon ischemia, native arterial rupture, and type 1 endoleaks are more frequent. Elective endovascular aneurysm repair benefits men more than women.

Our long-term EVAR experience indicates that 18% of patients require additional secondary procedures, and most of these patients can be managed by endovascular means with an acceptable overall mortality of 2.9%. Most type I and II endoleaks can be successfully treated by transluminal embolization, and most patients with delayed aneurysm rupture after EVAR can be successfully managed by endovascular or open surgical repair.

ACS is a potential complication of endovascular repair of r-AAA and negatively affects survival. Factors associated with the development of ACS include (1) use of an aortic occlusion balloon, (2) coagulopathy, (3) massive transfusion requirements, and (4) conversion of bifurcated stent grafts into aortouni-iliac devices. We recommend that, after endovascular repair of r-AAA, these patients undergo vigilant monitoring for the development of ACS.
