Abstract

Selective termination can be used to preserve normal fetus from the other fetus with chromosomal, structural abnormality in multifetal pregnancy. This case is about twin pregnant patient who had undergone in vitro fertilization and embryo transfer. In 18 weeks of gestation, we found that one of the fetus had cranical encephalocele and was in concern for the termination by using ultrasound guided intrcardiac injection of 2.5 ml of potassium chloride solution. After performing this procedure the other healthy female newborn was naturally delivered at 38 weeks gestation with weight of 2.8 kg.
