Physical
There are no exam findings which reliably rule in or out these diagnoses.
Labs
CBC, CMP, Lipase, Type and Screen, UA, +/- Blood cultures(graft infection), +/- Lactate(suspected mesenteric ischemia)
Imaging
CT- for the highest sensitivity a triple phase CT scan (non-contrast, arterial phase, delayed phase) is required. Usually you want to talk with radiology prior to this study.
Ultrasound- both point of care ultrasound and duplex ultrasound do not detect EVAR complications with high enough sensitivity to be use routinely.

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
