Aortic Stent Graft

Abdominal Aortic Stent Graft

Abdominal aortic aneurysm stent grafts are performed to bypass large aneurysms in the abdominal section of the aorta which could otherwise lead to life-threatening rupture.

About an Aortic Stent Graft

During the procedure, an interventional radiologist advances a catheter through a small incision in the groin to the site of the aneurysm. Through the catheter, the interventional radiologist places a fabric tube (graft) that is long enough to span the bulging area. The tube is held in place by a stent, which is a metal mesh tube. The stent exerts outward pressure against the graft and artery to keep the graft snuggly in position.

The blood then flows through the graft and bypasses the aneurysm. Without the pressure of flowing blood, the aneurysm will eventually shrink and the risk of rupture is greatly reduced.
