Minimally invasive treatment for ruptured aneurysm: Safe, reduces mortality
Date:3/25/2012

A burst aneurysm (a local area of bulge) in the abdominal aortathe largest blood vessel in the body is a deadly condition. In fact, about half of these patients don't make it to the hospital in time. Those who do more often than not face open surgery to repair the blood vessel. This study finds that a minimally invasive interventional radiology treatment for ruptured aneurysms called endovascular aneurysm repair (EVAR) is safer than open surgical repair and is associated with lower mortality rates, say researchers Society of Interventional Radiology's 37th Annual Scientific Meeting in San Francisco, Calif.

Abdominal aortic aneurysm is a local area of bulge or dilatation in the abdominal aorta. If left untreated, this bulge can increase in size andafter reaching a certain size--it can burst or rupture causing fatal internal bleeding. In the United States, 9 percent of the population over the age of 65 years has an abdominal aortic aneurysm, and there are 15,000 deaths per year from ruptured abdominal aortic aneurysms. A man is four times more likely to suffer an aneurysm of this kind than a woman, and smokers are also four times as likely to develop the condition.

"People with peripheral arterial disease are at risk of an aneurysm, which is a weakening and abnormal bulging of a major artery. Once this area of bulge ruptures, this can lead to fatal internal hemorrhage," explained Prasoon Mohan, M.D., co-author of the study from the department of diagnostic and interventional radiology at Saint Francis Hospital in Evanston, Ill. "Prior to the development of minimally invasive endovascular repair, it was customary for individuals to undergo open surgery, but now the majority of these elective aneurysm repairs are being done by endovascular technique. It's only a question now of getting clinicians and institutions to use the same technique in emergency settings for ruptured aneurysms," he added.

"We found that endovascular aortic repair
