1. Open abdominal surgery – Here we replace the damaged segment of the aorta with a synthetic graft which is sewn in place. By this technique, it takes about one month to recover.
2. Endovascular surgery – This is less invasive. The graft is attached to a thin catheter that is inserted into a groin artery and threaded up the aorta. The graft is a woven tube covered by a metal mesh support. It is placed at the site of the aneurysm and fixed in place by small hooks. The graft reinforces the diseased aorta and prevents its rupture.
The recovery time in case of endovascular surgery is short and takes 3-4 days to a maximum of one week. The follow-up appointments are more frequent because of the fear of leaks. They are done 6 monthly for the first year and then yearly. Long term survival rates are the same for both.
