Case Report: Pregnancy While Using an IUD

Abstract

Intrauterine contraception, mostly in the form of copper IUD or hormone-releasing system, is a widely used method with a high level of contraceptive security. Despite high contra- ceptive efficiency, pregnancy can still occur. Pregnancy with a levonorgestrel-releasing intrauterine system (LNG- IUS) in situ is very rare. Intracavitary pregnancy with an IUD can lead to a higher risk of infection and preterm birth. We present the case of a 28-year-old woman who was ad- mitted to our hospital due to pregnancy with an LNG-IUS 52 mg in the 9th gestational weeks (8 + 3 weeks). Sonog- raphy showed an intact pregnancy corresponding to the gestational week. The IUS was located in the lower part of the cavity at a considerable distance from the amniotic cavity. After extensive information on the benefits and risks, sonography-guided saline infusion hysteroscopy was car- ried out. The intact pregnancy and the IUS could be shown hysteroscopically. The removal of the IUS was carried out with a grasping forceps. There was no complication. After an inconspicuous course of pregnancy, the patient sponta- neously gave birth in 37 + 1 gestational weeks
