Nine cases of multiple pregnancies, including 7 sets of triplets and 2 sets of quadruplets, were enrolled for selective fetal reduction between March 1989 and July 1990 at the National Taiwan University Hospital. Under transabdominal or transvaginal ultrasound guidance, potassium chloride was injected into the fetal cardiac chamber to kill the selected fetus during the 10-14th gestational week. The number of fetuses was reduced to two in all cases. No maternal complications occurred during the procedure. Six gravidas have given birth to 6 sets of healthy twins; two pregnancies are progressing smoothly at 26 and 23 weeks of gestation, respectively, and one case underwent spontaneous abortion 4 weeks after the procedure. Selective fetal reduction under ultrasound guidance is an acceptable method of preventing high perinatal mortality and morbidity of immature fetuses in grand multiple pregnancies.
