EVAR repairs an aortic aneurysm from inside the artery. A folded stent-graft, a fabric tube supported by a metal frame, is passed through small punctures or cuts in the groin and opened inside the aneurysm. It creates a new channel for blood and takes pressure off the weakened wall. CT angiography is used first to assess whether the anatomy suits EVAR.
How the Procedure Can Help
EVAR avoids a large abdominal or chest incision, so pain, blood loss and hospital stay are usually less than with open surgery. It lowers the risk of the aneurysm rupturing.
Risks and Considerations
Leaks around the graft (endoleaks), graft movement, kidney strain from contrast dye and groin wound problems can occur, and some patients need a repeat procedure. Lifelong scans are needed to monitor the graft. Not every aneurysm is suitable, and open surgery may be advised instead.
