[Operative results with total composite replacement of the aortic valve and ascending aorta].

From December 1980 to December 1990, ten patients, 9 male and 1 female, ranging in age from 21 to 68 years, were operated on for aortic valve insufficiency associated with an aneurysm of the ascending aorta. The surgical treatment in all cases consisted of total replacement of the ascending aorta with Bentall's procedure (n = 4), or Cabrol's procedure (n = 6). In 5 patients an uncomplicated annulo-aortic ectasia existed. Three of them had annulo-aortic ectasia with an aortic dissection. One had aortitis syndrome, and one had syphilitic aortitis. The operative mortality for the entire group was 0% (0 death). Hospital survivors revealed satisfactory clinical improvement in NYHA class (mean value: 3.2 to 1.0). Late complications developed in 2 of the 10 patients. They had a picture of pseudoaneurysm formation at the anastomoses between the graft and the right coronary 46 months and 15 months, respectively, after the initial operation. Despite the reoperation, one died of hepatic failure 30 days after the operation, and the other died of postoperative bleeding at the anastomosis sites. We, furthermore, considered the difference in aortic cross clamp time and cardiopulmonary bypass time between Bentall's procedure and Cabrol's procedure. Aortic cross clamp time and cardiopulmonary bypass time were significantly shorter in Cabrol's procedure than in Bentall's procedure, if a probability value less than 0.20 was considered to be of statistical significance. We were able to conclude that the treatment of aortic valve regurgitation associated with an aneurysm of the ascending aorta by insertion of a composite graft is a reliable method with low operative mortality and excellent long term results, especially in Cabrol's procedure.
