Repeated ultrasound scans revealed hydrocephalus with macrocephaly (BPD = 10.3 cm), polyhydramnios (AFI = 31.5), and a suspected esophageal atresia. After counseling, both parents decided not to pursue the pregnancy and requested vaginal delivery. They decided against transabdominal, ultrasonic-guided cephalocentesis because of its invasiveness, patient's awareness, and pain. Skull decompression with the modified Smellie's perforator was performed after five 400-μg doses of misoprostol were applied to dilate the cervix. The post-partum condition was uneventful. Fetal skull decompression with the modified Smellie's perforator and misoprostol for cervix dilation is a useful, simple, and safe procedure that can be performed with no previous experience. © 2002 International Federation of Gynecology and Obstetrics.Mahidol UniversityMedicineArticleSCOPUS10.1016/S0020-7292(01)00561-6
