A Case of Anencephaly Associated with Twin Pregnancy Conceived by In Vitro Fertilization and Embryo Transfer / 대한산부인과학회잡지

Twin pregnancies are increasing these days due to recent development of the technology in treating infertility and twin pregnancies tend to cause more congenital anomaly than singleton pregnancies do. Although anencephaly is not uncommon, occurring in about one in every 1,000 births, anencephaly developed in a twin pregnancy is very rare. We experienced a twin pregnancy which consisted of an anencephalic fetus and a normal one. This pregnancy was conceived by IVF and ET. This pregnancy was continued without having special problems and was delivered at 36 weeks of gestation by cesarean section due to SROM (spontaneous rupture of membrane). The anencephalic fetus weighed 1,430 gm and was already dead in the uterus. The other weighed 2,660 gm and showed no external anomaly. Its Apgar score was 8 in 1 minute and 9 in 5 minute. The pregnancy resulted in a cesarean section delivery of one dead anencephalic fetus and one normal healthy fetus. We report with a brief review of literature a case of a twin pregnancy, conceived by IVF and ET, in which anencephaly was associated with a normal fetus.

Genetic amniocentesis after multifetal pregnancy reduction / 대한산부인과학회잡지

OBJECTIVE: This study is directed to evaluate the pregnancy loss rate resulting from genetic amniocentesis after multifetal pregnancy reduction. METHODS: From March 1998 to April 1999, total 145 patients with multifetal pregnancy were included in this study. Pregnancy loss in a study population of 44 patients who underwent genetic amniocentesis after multifetal pregnancy reduction were compared with a control group of 99 patients who did not have genetic amniocentesis after multifetal pregnancy reduction. RESULTS: The pregnancy loss rate in patients who underwent genetic amniocentesis after multifetal pregnancy reduction was 2.2% (1/44) compared with 4% (4/99) in the controls (P>.05). In the study group, one woman lost her pregnancy at 19 weeks' gestation, 3 weeks after the genetic amniocentesis, and the predisposing factor was spontaneous rupture of membranes. CONCLUSION: Genetic amniocentesis following multifetal pregnancy reduction does not increase the risk of pregnancy loss.

A Case of Prenatally Diagnosed Apert syndrome / 대한산부인과학회잡지

Apert syndrome or acrocephalosyndactyly is a rare developmental deformity with a sporadic or autosomal dominant trait characterized by coronal craniosynostosis, midface hypoplasia, exorbitism, typical symmetrical syndactyly of both hands and feet with varying degrees of mental retardation. It results from a mutation of the fibroblast growth factor receptor type-2 (FGFT2) gene. In the absence of family history, prenatal diagnosis may be difficult based on ultrasonographic findings alone. The original description was presented by Apert in 1906 with nine cases. Since then more than 200 cases have been reported in the world. We report a case of Apert syndrome diagnosed prenatally by ultrasonogram in the third trimester and subsequently was terminated, with a brief review of prenatal sonographic findings in 11cases reported in literature.
