We report a case of monochorionic diamniotic twin gestation confirmed by ultrasound visualization of the thin intertwin-dividing membrane at 32 weeks' gestation. Ultrasound at 36 weeks failed to demonstrate the thin dividing membrane. The pregnancy ended a few days later with spontaneous vaginal delivery of the first twin. The second twin was in transverse lie with no membranes that could be felt around. Severe fetal heart rate deceleration developed, prompting delivery by emergency caesarean section. Cord entanglement was noted at the time of delivery, which resulted in severe perinatal morbidity of the second twin. The antepartum rupture of the dividing membrane must have happened some time between 32 and 36 weeks. The etiology for this intrauterine disruption is unknown. A review of the literature about the antepartum rupture of the intertwin-dividing membrane is described, along with its possible causes and complications. In addition, we discuss possible causes of incorrect amnionicity determination, and thus how to minimize these pitfalls. We conclude that antepartum disruption of the intertwin-dividing membrane is more common than previously thought. Moreover, prenatal ultrasonographic visualization of a dividing membrane in a diamniotic twin pregnancy does not rule out future change in this environment to a monoamniotic one, with all its perinatal morbidity and mortality complications, which result mainly from cord entanglement. This suggests a modification in the method and frequency of the prenatal fetal well-being follow-up, as well as the time and mode of delivery.

The objective of this study was to evaluate the effect of the current guideline of 30-minute decision-to-incision interval (D-I) in emergent cesarean delivery (ECD) on neonatal and maternal outcomes. A retrospective chart review was conducted of pregnant women who underwent ECDs between January 1999 and December 2001. The overall median D-I was 20 minutes (range, 5 to 57 minutes). In 83 women (group I), D-I was < or = 30 minutes, and in 28 women (group II), it exceeded 30 minutes. Group I had more neonates with cord pH < 7.00, seizures, encephalopathy, and lower Apgar scores at 1 and 5 minutes than group II, but were not statistically significant. There was no significant difference in neonatal admission to the neonatal intensive care unit or length of stay between the two groups. Maternal complications were higher in group I, but not statistically significant. Although it was achieved in most of the ECDs, the guideline of 30-minute D-I does not seem to improve neonatal nor worsen maternal outcomes.

Introduction: Cesarean scar pregnancy (CSP) is defined as implantation of gestational sac at the site of cesarean scar. It's a serious diagnosis that has become more prevalent in recent years and related to the increasing rate of cesarean sections reported worldwide. Identifying these cases and treating them is challenging, with no agreed upon universal protocol for successful treatment. We aim to evaluate the success rate and outcome of medical management for Cesarean scar pregnancy. Methods: It was a retrospective descriptive study of all cesarean scar pregnancies managed at fetal medicine unit at Latifa Hospital in Dubai, UAE the main obstetrics & Gynecology tertiary hospital in Dubai Emirate, UAE from 2015 to 2017. Certainly, a set of diagnostic criteria were implemented to confirm the diagnosis of CSP. The cases were then offered our proposed management which is systemic methotrexate injections ± KCL. Follow up made by serial βhcg and ultrasound scan. The data were collected used specified data collection sheet for this purpose then analyzed and presented using statistical package for social sciences (SPSS) version 26. Results: 33 cases of cesarean scar pregnancies are confirmed and medically managed during the study period. The study subjects composed of a group of patients who had a viable CSP and received local KCL injection + systemic methotrexate, a second group who had non-viable CSP and received systemic methotrexate 20 cases were viable pregnancies who received combined local potassium chloride plus systemic methotrexate, and 13 were non-viable received systemic methotrexate only. The mean gestational age at diagnosis was 8 weeks (SD ± 1.8). On average our cases had a history of 3 previous cesarean sections (range 1-6). Overall, the success rate calculated from our study population for medical management of CSP was 77.8%; this varied between viable CSP which had a success rate of 66.
