Ruptured abdominal aortic aneurysm after endovascular aortic aneurysm repair.

In treating uncomplicated abdominal aortic aenurysm, endovascular aortic aneurysm repair (EVAR) has been employed as a good alternative to open repair with low perioperative morbidity and mortality. However, the aneurysm can enlarge or rupture even after EVAR as a result of device failure, endoleak, or graft migration. We experienced two cases of aneurismal rupture after EVAR, which were successfully treated by surgical extra-anatomic bypass.
