[Operative results of total replacement of the ascending aorta and aortic valve--characteristic difference between Bentall's and Cabrol's procedures].

From May 1979 to November 1991, 26 patients underwent total replacement of the ascending aorta and aortic valve. We employed 15 Bentall's procedure (group B) and 11 Cabrol's procedure (group C). There were no significant difference in age and etiology between the two groups. Inclusion technique was used in all patients. Compared group B with group C, both the operation time and the aortic cross-clamp time were significantly shorter in group C than in group B. (p < 0.05, p < 0.01 respectively). There were no operative death in group B and one in group C. There were two death in group B in later postoperative period. One was due to the anastomotic leakage at the distal site with infection, and the other was cardiac death caused by the infectious fistula between wrapping cavity and RA. The postoperative actuarial survival rate for group B at 12.8 years was 86.7% and that for group C at 5.1 years was 90.9%. The late complications such as coronary-graft anastmotic leakage or pseudoaneurysm, hematoma between the wrap and the graft and anastomotic leakage at the distal site were recognized more in group B. In group C no pseudoaneurysm were noted, but hematoma was noted in two patients. The rate of complications in late phase was significantly lower in group B (p < 0.05). Although as a procedure of total replacement of the ascending aorta and aortic valve both Bentall's and Cabrol's procedure represent satisfactory operative results, Cabrol's procedure has some advantages and fewer postoperative complications.(ABSTRACT TRUNCATED AT 250 WORDS)
