[Reinforcement cerclage of dystrophic aortic rings]

Reinforcement of a dystrophic aortic ring with a purse string suture makes it possible to obtain perfect coaptation between prosthesis and ring whilst inducing sclerosis. The technique described here was used by the authors in 30 patients operated upon since June, 1980, and none of these needed reoperation for leakage. These results contrast most favourably with those previously obtained in similar anatomical conditions with conventional prosthesis insertion.
