OBJECTIVES: To investigate the rate, success and pregnancy outcome following a trial of labor after cesarean (TOLAC) in twin gestations. Study design: A retrospective study including all twin pregnancies with a single prior cesarean delivery between the years 2006 to 2011 was performed. Women with medical indications for cesarean delivery (CD) were excluded. Maternal and neonatal outcomes were compared between women who delivered by CD to those who underwent TOLAC. Stratified analysis using a multiple logistic regression model was performed to control for confounders...

The incidence of single fetal death in twin pregnancy varies from 0.5% - 6.8%, leaving the surviving fetus with increased morbi-mortality. The prognosis is worse in monochorionic pregnancies. In addressing these cases it should be noted referral to tertiary center with differentiated perinatal support, induction of fetal lung maturation and termination of pregnancy if there's loss of fetal well-being or possibility of maternal complications and suspected neurological sequelae in the surviving fetus. The risk of iatrogenic prematurity should always be weighed with the possible consequences arising from the fetus staying in a hostile uterine environment...

BACKGROUND: Several epidemiological studies have determined that assisted reproductive techniques (ART) can increase the risk of placenta previa. To date, only a meta-analysis has been performed for assessing the relationship between placenta previa and ART. This meta-analysis was conducted to estimate the association between placenta previa and ART in singleton and twin pregnancies. METHODS: A literature search was performed in major databases PubMed, Web of Science, and Scopus from the earliest possible year to April 2017...

OBJECTIVE: A survival-time regression model for the gestational age at delivery with preeclampsia (PE) in singleton pregnancies using maternal demographic characteristics and medical history was previously reported. The objective of this paper is to extend this model for dichorionic (DC) and monochorionic (MC) twin pregnancies. METHODS: The study population included 1,789 DC and 430 MC twin pregnancies and 93,297 singleton pregnancies. A survival-time model for the gestational age at delivery with PE was developed from variables of maternal characteristics and history...

BACKGROUND: Recent data suggest that singleton fetuses conceived by assisted reproductive technologies (ART) present cardiovascular remodeling that may persist postnatally. Twin pregnancies are more frequent in the ART population, and are associated with increased adverse perinatal outcomes like hypertensive disorders, gestational diabetes and preterm birth. However, it is unknown whether cardiac remodeling is also present in twin pregnancies conceived by ART. Our aim was to assess the presence of fetal cardiac remodeling and dysfunction in twin pregnancies conceived by ART, as compared to spontaneously conceived (SC) ones...

STUDY QUESTION: Is supraphysiologic estradiol (E2) an independent predictor of low birth weight (LBW) in singletons born after fresh IVF-embryo transfer (ET) cycles? SUMMARY ANSWER: Our results suggest that E2 > 2500 pg/ml is an independent predictor for LBW in full-term singletons born to normal responder patients undergoing fresh IVF-ET cycles. WHAT IS KNOWN ALREADY: The pathogenesis of LBW in IVF singletons remains unknown. However, recent studies have suggested that the hyperestrogenic milieu generated during ovarian stimulation may create a sub-optimal peri-implantation environment, leading to placental dysfunction, and therefore, LBW...

INTRODUCTION: The incidence of multiple gestations is increasing worldwide and many studies have shown higher perinatal morbidity and mortality rates in monochorionic twins compared to dichorionic. The aim of this study was to assess the twin population born at a tertiary center and to evaluate the impact of chorionicity on perinatal outcomes of twin pregnancies. MATERIAL AND METHODS: Retrospective study of all twins born in a tertiary center from January 2004 to December 2013...

Heterotopic pregnancies are rare and are usually diagnosed by transvaginal ultrasound. Despite the routine use of sonography in early pregnancy, artifact created by mirror imaging can drastically and erroneously alter medical decision making by interfering with image interpretation. A heterotopic pregnancy with a single intrauterine gestation and twin left adnexal ectopic gestational sacs was observed on ultrasound in a woman presenting with abdominal pain. During laparoscopy, an ectopic pregnancy was not identified, and subsequent intraoperative ultrasound reproduced the heterotopic pregnancy through manipulation of bowel, confirming mirror image artifact...

We performed a dual-gate Doppler examination for a twin reversed arterial perfusion (TRAP) sequence in a monochorionic-triamniotic triplet pregnancy at 16 weeks of gestation and were able to identify the pump twin by arterial pulse rate synchronicity. We performed radiofrequency ablation to coagulate blood flow in the acardius at 16 weeks of gestation without any postoperative complication. At 29 weeks of gestation, we performed a cesarean section due to preterm rupture of the membranes and the patient delivered 1167/1237-g female neonates and a macerated acardius...

To evaluate the relative risk of placental abruption in monochorionic (MC) twin pregnancies complicated with twin-to-twin transfusion syndrome (TTTS) and treated with endoscopic laser coagulation of placental vessels (ELCPV). A retrospective analysis from January 2004 and December 2015 of 373 TTTS pregnancies, treated with selective ELCPV until January 2012 (287 cases), after which the Solomon technique was introduced (86 cases), compared with 243 normal MC pregnancies. A significant improvement in perinatal survival was observed after the introduction of the Solomon technique when compared to the selective procedure (77% vs 54%, p < 0...

OBJECTIVE: To explore the hypothesis that selective placental pathology affecting the nonpresenting twin is a significant contributory factor mediating the smaller size at birth of nonpresenting dichorionic twins. METHODS: We conducted a retrospective cohort study of all dichorionic twin deliveries in a single tertiary center between 2002 and 2015 where by departmental policy, all placentas from multifetal gestations are routinely sent for pathologic examination...

Massively parallel sequencing (MPS) technology has become increasingly available and has been widely used to screen for trisomies 21, 18, and 13 in singleton pregnancies. This study assessed the performance of MPS testing of cell-free fetal DNA (cffDNA) from maternal plasma for trisomies 21, 18, and 13 in twin pregnancies. Ninety-two women with twin pregnancies were recruited. The results were identified through karyotypes of amniocentesis or clinical examination and follow-up of the neonates. Fluorescent in-situ hybridization was used to examine the placentas postnatally in cases of false-positive results...

Umbilical cord entanglement is the leading cause of fetal mortality in monoamniotic twin pregnancies and a pseudo monoamniotic environment. Published methods for detecting this complication include color Doppler and pulsed Doppler sonography; however, no method provides an absolute diagnosis. In this case, we report the diagnosis of umbilical cord entanglement using dual-gate Doppler imaging. A 35-year-old woman was referred to our hospital at 28 weeks of gestation for prenatal management because of diagnosis of a monochorionic diamniotic twin pregnancy with spontaneous septostomy of the dividing membranes...

BACKGROUND: There is currently insufficient evidence regarding the prognosis of multifetal pregnancy following elective fetal reduction to twin or singleton pregnancy. We compared perinatal outcomes in pregnancies with and without fetal reduction. METHODS: We used data on all stillbirths and live births in British Columbia, Canada, from 2009 to 2013. We compared outcomes of multifetal pregnancies with fetal reduction (to twin or singleton pregnancy) with outcomes of pregnancies without fetal reduction...
