Knowing the unique complications of EVAR is the first and most important step in the management of these patients.
Unfortunately, while CT is sensitive for most complications of EVAR it does NOT definitively exclude Aortoenteric Fistula, Graft infection or endoleaks. Maintain a high index of suspicion when a EVAR issue is suspected and always lean toward conservative management/early specialist consultation.
Aortic endograft complications
Aortoenteric Fistula 
Heart transplant complications
Endoleaks- Vascular flow outside of the graft that is still contained in the aortic aneurysm. This can lead to worsening AAA and ultimately rupture.
Aortoenteric fisulta
Type 1: the seal of the graft fails
Left ventricular assist device complications
Type 2: a collateral vessel leaks
