EVAR for Abdominal Aortic Aneurysms

An abdominal aortic aneurysm (AAA) is a swelling or enlargement in the lower part of the aorta, the main artery in the body. Depending on the AAA, surgery such as endovascular aneurysm repair (EVAR) may be required to treat it.

Here to provide an expert insight into EVAR surgery, including risks, recovery and results, is Mr Said Abisi, award-winning consultant vascular and endovascular surgeon.

What is EVAR surgery?

EVAR is a minimally invasive surgical procedure used to repair abdominal aortic aneurysms (AAAs).

During the procedure, a stent-graft (a fabric tube) is placed inside of the affected section of the aorta. The stent-graft then redirects blood flow away from the AAA, preventing the AAA from rupturing.

When is EVAR surgery necessary?

EVAR surgery is required for patients who have been diagnosed with an AAA that is at risk of rupture. This risk is determined by the size of the AAA and the patient's overall medical condition. 

Are there any major risks or complications?

Possible risks of EVAR surgery include bleeding, infection, and damage to the blood vessels or to the organs surrounding the aorta. As well as this, there is also a small risk of the AAA re-occurring or the stent-graft becoming displaced. 

What is recovery like?

Although the recovery time can vary, the majority of patients are able to return to their normal activities within a few weeks.

In some cases, rehabilitation may be recommended to strengthen the muscles and increase mobility.

Are the results of EVAR surgery permanent or are follow-up operations required?

The results of EVAR surgery are generally considered to be permanent. However, the stent-graft might need to be replaced in the future if it becomes damaged or detached.

Regular follow-up scans are generally required to monitor for any changes occurring in the AAA.
