[I.U.D., pregnancy, perforation of the uterus (author's transl)].

The author report a case of pregnancy reaching as far as the 37th week in a patient holding an I.U.D. certainly in site at the beginning of pregnancy and with asymptomatic perforation of the uterus during the pregnancy with incorporation of the device by the omentum. Emphasis is laid on the importance of echographic monitoring for the location of I.U.D.s especially when the anchor thread of the device is not to be found in the vagina and initial pregnancy is suspected. On the other hand, as yet available data are not sufficient for assessing the influence of copper devices on the fetal condition.
