Endovascular repair is a vascular surgery procedure to treat an abdominal aneurysm. An aneurysm is a bulge in the wall of an artery.

The abdominal aortic aneurysm is located in the main blood vessel in the body, the aorta, that brings oxygen-rich blood from the heart to the chest and the belly.

Aneurysm Surgery

If your aneurysm is larger than 5 cm, it is more likely to tear and you may need surgery. Small abdominal aneurysms often don't need treatment but it is advisable to have them monitored over time.

What Does Abdominal Aneurysm Repair Involve?

After a thorough consultation with your Vascular Surgeon, you need to undergo a few examinations to assess your case:

  • Blood test
  • Electrocardiogram (ECG)
  • Echocardiography: this can look at the size of your aneurysm
  • CT scan for a detailed image of your aneurysm.
  • Angiography

Endovascular Repair

The procedure will be performed under general anaesthetic. 

Your vascular surgeon will make a small cut in your groin and into an artery and then insert a thin, flexible catheter into the artery. The catheter is a tube that will be gently guided all the way to where your aneurysm is located. Moving X-ray pictures will help the surgeon to reach the right spot.

Together with the catheter, the surgeon will send a stent graft, another tube made of a thin metal mesh, covered with a thin polyester fabric, that opens once it reaches the aorta and fastened in place.

The stent graft will be in place to allow the blood to flow without further damaging the aorta wall, preventing the aneurysm from bursting.

The catheter is then removed and the incision in your groin closed.
