Abstract

Intrauterine, ultrasound-guided removal of a copper-releasing intrauterine contraceptive device (IUCD) was carried out in 26 first-trimester pregnancies. In all the pregnancies, the string of the device had retracted into the uterine cavity. The total loss of pregnancies was 46%, while 36% of the initially uncomplicated single pregnancies ended in a spontaneous abortion. The time lag between the removal of the IUCD and clinical abortion was 21.5 days (range 3-48 days). A fundal location of the IUCD and failure to remove the IUCD by the first traction were common features in the abortion group. A total of 14 of the pregnancies resulted in a liveborn baby, and the incidence of complications after the 20th gestational week was not increased compared with the normal population.
