Rarefaction of the aorta under Dacron wrap: A rare complication

Treatment for ascending aortic dilatation varies from a wait-and-watch approach to aortic replacement. The use of an external prosthesis to gird and support the proximal aorta is safe and durable for selected aortic aneurysms. We report a rare complication in a 62-year-old man with bicuspid aortic valve and coronary artery disease who had undergone coronary artery bypass surgery and ascending aortic wrapping 10 years previously. During subsequent aortic valve surgery, he was incidentally found to have erosion of Dacron wrap through the aortic wall.
