An aortic dissection occurs when a layer of the body’s main artery separates, disrupting blood flow to vital organs.
Dr. Paul DiMusto, a UW Health vascular surgeon and co-director of the UW Health Aortic Center, said many patients have no symptoms until the event occurs, and it is often life-threatening.
