Which treatment works the best and fastest for dissecting aortic aneurysm?

Surgery: There is only one curative treatment - emergency surgery!

TO THE O.R.!: Aortic dissection may be treated with medical management or emergent surgery. With the improvement of endovascular grafts, surgical repair seems more common. A vascular surgeon will advise based on anatomy and location of dissection, vessels/organs involved. I've seen a few interventional radiologists do things also. Most important is immediate evaluation!
