EndoVascular Aortic Repairs are a game changer in patients with AAAs. Add a T and you get a TEVAR for the treatment of aortic dissections. Despite the amazing advances that these devices represent, they are not without problems.

Recently Done Operation
Look at the Access Site in the groin. These devices require enormous access in the femoral vessels. Search for pseudoaneurysms, dissection, thrombosis, or bleeding.
Kidney injury both from operation and all of the imaging that goes along with it
Leaks through or around the graft into the original aneurysm.
Get imaging. Don't get ad hoc imaging. They need specialized CT angiography of the chest and abdomen with both arterial phase and delayed venous phase. You really want to work the scan parameters out ahead of time with your radiologists.
- Type 1: Failure of complete apposition to vessel wall (1a is proximal, 1b is distal)
- Type 2: Retroleak – Back flow through a vessel
- Type 3: Graft torn or ruptured
- Type 4: Porosity of the graft
- Type 5: Unclassified/Who Knows?
Type 1 and Type 3 needs immediate surgical intervention
for the others, Aortic dp/dt control just like a dissection until you get in touch with Vascular
Thrombosis and Embolus
These pts can through clots to their distal vessels
Look for arterial clots and for mesenteric ischemia

anytime someone has any issue with their EVAR, call early!!!!
