[Death in utero of a fetus in multiple pregnancies (author's transl)].

Six intrauterine deaths which occurred in the course of our survey of 160 multiple pregnancies are reported here. The way of handling them obstetrically is discussed, taking note of the facts given in the literature. When prevention is possible it rests on consecutive clinical and paraclinical observation. Ultrasound tomography is of the greatest possible value to diagnose poor intrauterine growth in one fetus. When one has died and this has been confirmed, routine Caesarean section seems to be indicated to allow the remaining twin to escape, as much from the risk of chronic fetal distress as from the added risks that follow on the retention of a dead fetus.
