[Acute abdomen caused by an intrauterine device]

Case report about late complications caused by lying intrauterine devices (IUD). Ileus by strangulation represents a rare event when a closed IUD has perforated partially. A pelvic roentgenographic examination alone is not sufficient in order to give an estimation of the present position of the IUD. Results of hysterography and ultrasonographic examinations should be taken into account as well.
