Minimally invasive surgery works well for abdominal aortic aneurysms, Mayo finds
Date:9/5/2012

ROCHESTER, Minn. -- A minimally invasive procedure known as endovascular repair used for abdominal aortic aneurysms has a low rate of complications, even in high-risk patients such as those with kidney, heart or lung problems, a Mayo Clinic study shows. Researchers found that even when aneurysms ruptured, endovascular repair had lower mortality rates than open-abdominal surgery, the other treatment option. The findings are being presented at the Midwestern Vascular Surgical Society Annual Meeting, Sept. 6-8, in Milwaukee, Wis.

An abdominal aortic aneurysm is a weakened and bulging area in the lower part of the aorta, the major blood vessel that supplies blood to the body. A ruptured abdominal aortic aneurysm can cause life-threatening bleeding. In endovascular surgery, physicians attach a synthetic graft to the end of a thin tube, or catheter, inserted through a groin artery and threaded up into the aorta. The graft is placed at the site of the aneurysm and fastened in place, reinforcing the aorta to prevent rupture. Recovery time typically includes a day in the hospital and one or two weeks of rest at home, compared with five to seven days in the hospital and four to six weeks at home after open-abdominal surgery.

"During the last decade or so we have performed over 1,000 endovascular repairs of abdominal aortic aneurysms that included patients with no symptoms at all and patients who presented with a life-threatening rupture. We
