[Surgical treatment of acute ascending dissection--a simplified operative method].
Primary anastomosis for acute ascending aortic dissection was performed in 8 patients. Primary anastomosis included resection of the intimal tear where applicable, a circumferential suture line in the ascending aorta at the site of the tear, and wrapping of the anastomosis of the ascending aorta with Dacron vascular prosthesis. The aortic valve was resuspended in 1 of 6 patients associated with aortic regurgitation. In 4 patients, aortic regurgitation disappeared postoperatively. Two patients show minor non-progressive valve regurgitation. Two of 8 patients died early postoperatively. There was no late death and dilatation of the aortic root in the follow-up period of mean 27 months. On the basis of these results, we believe that primary anastomosis is a simpler and safer operative method for acute dissection of the ascending aorta.
