[Experience with hysteroscopy or ultrasound-controlled removal of an intrauterine spiral with no visible thread in early pregnancy].

In case of intrauterine pregnancy with an intrauterine device (IUD), it is recommended, to remove the device because of the risk of abortions or septic complications. If the thread of the IUD is not visible, which often occurs because of growth of the uterus in pregnancy, it is advisable, to perform extraction by hysteroscopy or ultrasonic guidance. We report on 13 cases with hysteroscopic or ultrasonic guided IUD extraction in early pregnancy. 11 resulted in healthy infants, two pregnancies are continuing without complications.
