The concern of ART treatment on maternal transport cases in the tertiary perinatal center

Abstract

OBJECTIVE: The purpose of this study was to evaluate the concern of ART treatment in the tertiary perinatal center.DESIGN: Retrospective study.MATERIALS AND METHODS: From January 2003 to December 2007, there were 1790 deliveries in our tertiary perinatal center. There were 958 referred cases including 48 ART treatments (24 conventional IVF-ET, 1 ICSI, 13 cryopreserved embryo transfer, 10 cryopreserved blastocysto transfer). In these cases, factors for referral and obstetrical outcomes (multiple pregnancies, pregnancy outcomes, congenital anomalies, growth restriction) were studied.RESULTS: Common factors on referral cases were 201 threatened premature labor including 11 ART cases, 69 maternal complications including 2 ART cases, 62 multiple pregnancies including 14 ART cases, 57 IUGR (intrauterine growth restriction) and PIH (pregnancy induced hypertention) including 8 ART cases, and 31 congenital anomalies including 3 ART cases. In referral cases, there were 193 emergency maternal transports including 7 ART treatments. The most common factor for emergency transport was threatened premature labor (123 cases including 7 ART). About referral multiple pregnancies, there were 4 triplet pregnancies including 1 ART, 38 DD (dichorionic, diamnionic) twin pregnancies including 9 ART, 18 MD (monochorionic, diamnionic) twin pregnancies including 4 ART, and 2 MM (monochorionic, monoamnionic) twin pregnancies. Those multiple pregnancies were 14 cases after ART (assisted reproduction technology), 15 after OI (ovulation induction), and 33 natural conceived. There were 7 TTTS (twin-to-twin transfusion syndrome) pregnancies including 3 ART cases. The number of spontaneous abortions and still births was 59 including 10 after ART. In cryopreserved blastocysto transfer cases, IUFD (intrauterine fetal death) and congenital anomalies were more frequent than other ART treatments.CONCLUSIONS: In emergency maternal transport, there was no concern of ART treatment. However, the increased risk of multiple pregnancies, TTTS, IUFD, and congenital anomalies was noted in ART treatment cases.
