Endovascular Aneurysm Repair

This alternative to open surgery is most commonly used to treat an abdominal aortic aneurysm (AAA) by inserting an expandable stent graft to support the aorta – with far less risks and complications than traditional methods. Abdominal Aortic Aneurysms are most concerning when there is a risk the aortic aneurysm may burst – resulting in massive internal bleeding.

Abdominal Aortic Aneurysm

Am I A Candidate for Abdominal Aortic Aneurysm treatment?

An aneurysm can be detected when you have an ultrasound or CT scan for another reason. If detected, you and your doctor will discuss whether the aneurysm needs to be repaired, and whether the risk of the procedure is less than the risk of rupture. Your physician is likely to recommend Endovascular Aneurysm Repair (EVAR) if your aneurysm is:

  • Large in size (about 2 inches or 5 cm)
  • Growing quickly (averaging 1/4 inch over the last 6 to 1 year)

How Does Endovascular Aneurysm Repair Work?

Endovascular aortic aneurysm repair is performed when an aneurysm is very large, growing quickly, or is leaking or bleeding.

During the procedure, the patient will receive general anesthesia and one of our Interventional Radiologists will insert a stent – a man-made, metal coil, through the femoral (groin) artery which lead to the location of the aneurysm.

Using imaging guidance, our Radiologist will guide the sent up into the aorta. Once placed, the stent’s spring-like mechanism will attach itself to the walls of the aorta. The ballooning aneurysm will begin to shrink around the stent. The Radiologist will confirm the stent is in the right place, and that the aorta is not damaged and the aneurysm is not bleeding inside the body.

After the Procedure

One of our Interventional Radiologists will interpret your results and advise you whether the procedure was a success. During a follow-up visit, your physician may discuss any additional treatment you may need or if you experience any side effects of the procedure.
