Extended aortic grafting for acute ascending dissection after type B dissection

A 31-year-old man was diagnosed with acute ascending aortic dissection and massive aortic regurgitation following acute type B dissection during drug treatment. Although the aortic arch was not dissected, we performed aortic replacement from the aortic root to the proximal portion of the descending aorta. The aim of the operation was the prevention of aortic arch dissection, and closure of initial entry of type B dissection.
