Intrauterine transfusion in an Rh-immunized twin pregnancy: a case report of successful outcome and a review of the literature.

Fifteen sets of twins have been reported among 2331 pregnancies complicated by Rh alloimmunization of sufficient severity to warrant intrauterine transfusions. Four of the 15 sets were managed in Winnipeg, Canada. One of the four is described in detail in the present report. Serial amniocenteses (N = 15) and intrauterine transfusions (N = 8) were used in the management of the dizygous affected twin fetuses with a favorable outcome. Factors contributing to the survival of the twins are described.
