OBJECTIVE: To improve perinatal survival rates by prolonging the rest of the pregnancy after an abortion or extremely premature birth of one fetus in multiple pregnancies, especially in women with low fertility potential. METHODS: Following the expulsion of one fetus a cervical cerclage was applied to all patients. The placenta of the expelled fetus including a small portion of its cord after it was ligated close to the external os, was left in situ. The patients were invariably kept on bed rest until the pregnancy was completed under close observation, tocolysis and preventive antibiosis. After the 24th week of gestation corticosteroids were administered. RESULTS: The delivery interval achieved ranged between two and 135 days, the longest reported. Although the survival rate was relatively low (40%) all but one of the women (83%) managed eventually to have a live child, one with twins. CONCLUSIONS: In selected multiple pregnancies the attempt to prolong the rest or the pregnancy, following the abortion or the extremely premature birth of one fetus, seems efficacious and justified especially in women with a history of long-term infertility.
