[Pregnancy with an intrauterine pessary in the placenta].

A case of a 23 year old patient which had become pregnant with a copper-T-IUD in situ is presented. After a pregnancy without many complications a healthy child was born. The copper-T-IUD was partially embedded in the placenta. Usually the delivery of a living and healthy child will not take place if a foreign body is situated in the placenta. If a woman becomes pregnant in spite of an IUD in situ, the IUD should be removed, even if this removal should terminate pregnancy. The risk of septic abortion in a pregnant woman with an IUD in situ is 1 in 15 to 1 in 30.
