[The surgical treatment for acute aortic dissection and changing concept of surgical procedures]

The first prominent report on the surgical treatment for acute aortic dissection was published by DeBakey in 1975. Since then, many various techniques have been applied for the surgery on dissection at ascending aorta and aortic arch. The basic understanding for the surgical treatment are focused to the climination of intimal tear as well as resection and closure of dissecting lumen and restore the blood flow only to the true lumen. The associated complications such as acute dissection AR should also be repaired simultaneously. At the present, the graft replacement of ascending aorta has become first choice of procedure. No matter where the intimal tear is located, the simultaneous replacement of assending aorta and aortic arch has been proposed recently as the most radical approach toward Type A dissection, although this extended approach has to be carefully evaluated in the future.
