[Twin pregnancy complicated by single intrauterine death. Report of six cases and literature review].
From 1982 to 1991, six twin pregnancies, in which one of the fetuses died in utero, have been encountered. The causes of antepartum death in twin gestation could be identified in four cases; one with abruptio placenta, one with twin-to-twin transfusion syndrome, one with twisting of cord and one with velamentous insertion of cord. All six surviving infants had no abnormality in the follow-up of two to seven years. Although a conclusion about the prognosis could not be drawn from such a small series, these good results may have resulted from 1) 2 cases having been dichorionic twins, and 2) the other 4 monochorionic twins of 31-36 gestation weeks were delivered 1 to 5 days after the diagnosis. Conservative treatment was usually suggested until the fetal lung was mature enough for induction of labor. One case was treated after the death of its counterpart with tocolytic agent for a further 15 days because of prematurity. Cesarean section was performed finally for fetal distress resulting from chronic abruption placenta. The other five cases were delivered through vaginal route. According to experience as well as literature review, to improve the prognosis, obstetricians should be familiar with the management of one fetal death in twin pregnancy, especially in those with monchorionic twins.
