[Intrauterine contraception by plastic intrauterine devices (2 personal cases of failure)]. / Contraception intra-utérine par les appareils plastiques intra-utérins (à propos de 2 observations personnelles d'échec)

PIP: IUDs and tubal sterilization (both defined as types of uterine sterilization suitable for medical indications only) are reviewed, and 2 cases of failure, one with a Lippes loop and one with the Madlener sterilization method are presented. The IUD patient had a Lippes loop inserted in Tunis, then had a normal pregnancy diagnosed 11 months later in France. She delivered a 2780 gm boy prematurely 6 months later. The other patient had a Madlener sterilization performed 11 years before in Germany after 4 caesarean births. She carried the 5th pregnancy to term and received an Irving sterilization. It was concluded that plastic IUDs should be used only where oral contraceptives or tubal sterilization are contraindicated, that the same protocol should be followed as for surgical sterilization, and that the patient and doctor should be alert to the possibility of failure (e.g., expulsion, pregnancy) and the dangers (perforation, occlusion) of the IUD.^ieng
