[Rupture of the pregnant uterine horn following salpingectomy with resection of the interstitial portion. Report of 3 cases of which one followed in-vitro fertilization and embryo transfer].

Uterine horn pregnancies are rare among ectopic pregnancies. Total salpingectomy with resection of the interstitial portion of the tube is usually recommended in order to prevent implantation in the interstitial stump. Three personal case histories of rupture of the uterine horn early in pregnancy, which all followed resection of the interstitial portion, have led the authors to discuss the physio-pathological mechanisms that lead to intra-mural implantations. The value of total salpingectomy in preventing these accidents is also considered. One of these three cases particularly interested the authors because it followed in vitro fertilisation and embryo transfer. This case has to be added to the twenty series already published of ectopic pregnancies after this treatment for sterility.
