[Biological and synthetic prostheses in gynecologic microsurgery].

Biological prostheses of human umbilical vein and synthetic prostheses of ePTFE were comparatively studied in the microsurgical anastomosis of the uterine horns in twenty rats. Patency rate after 30 days was 60% for umbilical vein and 75% for the ePTFE prostheses. Gross and histological examination of umbilical vein graft specimens showed minimal alteration with a smooth intimal surface. On the contrary tissue covering the inner surface from the adjacent ends of the uterine horns was noted in ePTFE prostheses.
