What are the predominant causes and management options for late rupture of abdominal aortic aneurysm after previous endovascular repair?
Graft-related endoleaks are the main cause of late AAA rupture post-EVAR, highlighting the critical importance of post-EVAR surveillance and the feasibility of endovascular re-intervention.
Graft-related endoleaks appear to be the predominant causes of late aneurysm rupture. Quality of and compliance with post-EVAR surveillance are important factors in late rupture; a large proportion of late ruptures are amenable to endovascular treatment.
