[The protection of an internal mammary artery graft with a tubular prosthesis made of polytetrafluoroethylene].

A polytetrafluoroethylene tubular prosthesis was used to protect an internal mammary artery graft in a patient with high risk of reoperation. This technique was used to avoid the risk of damage of the graft and to reduce the difficulties of the injection of cardioplegia during the reoperation procedure. The usefulness of this technique is discussed in the article.
