Endovascular Abdominal Aneurysm Repair (EVAR)

Make an Appointment

Endovascular abdominal aneurysm repair (EVAR) is a procedure used to treat aortic aneurysms in the abdomen. The procedure inserts a synthetic tube (called a stent-graft) into your aorta. This tiny device protects the aorta from tearing.

In the past, we treated abdominal aneurysms with open surgery. Open surgery involves large cuts on your body and a longer recovery time. EVAR only needs a small cut in your groin. Through there, we put a tube into a blood vessel that delivers the stent-graft where it's needed (it's a minimally invasive procedure). That means fewer complications and a quicker recovery.

Our vascular surgery team has extensive experience repairing abdominal aortic aneurysms. We’ve been nationally recognized for our advanced aortic aneurysm care by U.S. News and World Report for the last five years.

Is EVAR Right for My Aortic Aneurysm?

How we treat your abdominal aortic aneurysm depends on its location and size. Not all aneurysms can be treated with endovascular repair. If EVAR isn’t right for you, you may still have open surgery. Your doctor will talk with you about the best treatment for your situation.

Do You Need Aneurysm Treatment?

Your aorta is the largest blood vessel in your body. Aneurysms are bulges in the wall of the aorta. They make your aorta weaker. Aneurysms in the aortic wall can tear, which is a life-threatening emergency.

Your doctor will watch your aneurysm to see how big it is and how quickly it grows. Smaller aneurysms are less likely to tear and can be monitored.

What to Expect During EVAR

The procedure is done by a surgeon on our vascular surgery team. They will:

  • Give you anesthesia to put you to sleep
  • Make a small cut (incision) into an artery in your groin
  • Put a small, flexible tube (catheter) into the blood vessel
  • Thread the catheter through the artery to your aortic aneurysm
  • Send a short tube made of fabric and metal (stent-graft) to the aneurysm through the catheter
  • Open the stent graft and lock it in place
  • Remove the catheter and close the incision in your groin

The stent-graft lets blood flow past the aneurysm without putting pressure on it.

Recovering from EVAR

In most cases, recovering from an EVAR procedure involves staying in the hospital for only one night. There we can control any pain and watch for complications.

At home, you’ll need to take it easy for some time. Your doctor may ask you to limit some of your activities. You’ll also get medicine to prevent blood clots.

We’ll follow up with you to check on the stent-graft. You may need regular imaging exams to monitor the aneurysm. Over time, it should get smaller.

You should call your doctor right away if you have:

  • Bleeding from the incision that doesn’t stop
  • Pain in your leg from the incision
  • Redness or other color changes in your leg
  • Pain in your chest or stomach
