EVAR is a minimally invasive procedure used to repair aneurysms, or weakened areas, in artery walls. This procedure requires only small incisions in the groin where a stent is attached to a catheter and threaded to the affected area of the aorta.
Using an X-ray for visual guidance and specially designed instruments, surgeons repair the aortic wall with a stent-graft. A stent-graft uses a stent, which is a long, cylinder-like tube made of thin, metal mesh framework and a graft, which is made of different materials. The stent is used to hold the graft open and in place.
