    Abstract:
    Early growth retardation in one twin is complicated by a high fetal mortality and morbidity. It is often very difficult to determine the optimum time of delivery in regard to placental insufficiency and prematurity. We report of two cases in which doppler velocimetry was a helpful method in monitoring those pregnancies at high risk. A growth retardation of three weeks was found in one child of a twin pregnancy at 17 weeks of gestation. Doppler velocimetry at 23 weeks showed a reverse flow and centralisation and the child died at 27 weeks. The other twin then also developed pathologic flow patterns and had to be delivered by cesarean section. In the second patient, pregnancy could be continued in spite of a growth retardation of three weeks in one child at 15 weeks and an additional decrease in the growth rate of both children from 30 weeks onwards. Cesarean section had to be performed at 34 weeks because of premature rupture of membranes.
