This is a minimally invasive option since surgeons do this type of surgery using catheters (tubes) inserted into the arteries; it doesn’t require surgically opening the chest or abdomen. In endovascular repair, the aneurysm isn’t removed. Instead, a graft is inserted into the aorta to strengthen it. General anesthesia is used during this procedure.
The surgeon first inserts a catheter into an artery in the groin (upper thigh) and threads it to the aneurysm. Then, using an x-ray to see the artery, the surgeon threads the graft (also called a stent graft) into the aorta to the aneurysm.
The graft is then expanded inside the aorta and fastened in place to form a stable channel for blood flow. The graft reinforces the weakened section of the aorta. This helps prevent the aneurysm from rupturing.
