BACKGROUND Impact of fetal gender on prematurity has been primarily investigated in singleton pregnancies. In an attempt to understand better how fetal gender may affect gestational length in twin gestations after in vitro fertilization, same-sex twins and opposite twins were compared for pregnancy duration. METHODS This study evaluated 113 women at ages 20 to 39 years with consecutive dichor...

OBJECTIVE To construct monochorionic diamniotic (MCDA) and dichorionic diamniotic (DCDA) twin reference ranges for umbilical artery (UA) pulsatility index (PI), UA resistance index (RI), fetal middle cerebral artery (MCA) PI and peak systolic velocity (PSV) and cerebroplacental ratio (CPR) from 24 weeks' to 38 weeks' gestation and compare these with published normal values for singleton pregnan...

The chorionicity-based evaluation of the perinatal risk in twin pregnancies after assisted reproductive technology (ART) is lacking. A retrospective review was performed of all twin pregnancies monitored prenatally and delivered at our hospital between 2010 and 2014. Chorionicity was diagnosed by ultrasound examination at first trimester and confirmed by postnatal pathology. Pregnancy and perin...

The purpose of this article was to evaluate the accuracy of predicting amnionicity using the number of yolk sacs by diagnostic ultrasound examination in monochorionic (MC) multifetal pregnancies between 7 + 0 and 9 + 6 gestational weeks. A total of 97 patients with MC multifetal pregnancies underwent early ultrasound examination from 2004 to 2014 at Cheil General Hospital and Women's Healthcare...

Abstract Background Monochorionic twins have higher perinatal morbidity and mortality than dichorionic twins. However, there is conflicting data on outcomes of uncomplicated monochorionic Purpose the Study The aim this study to compare apparently Methods This a prospective conducted from August 2019 December 2020 at specialized twin clinic. All twins, whose chorionicity was determined before 14...

A twin gestation invariably leads to a certain extent of cervical length shortening . If this reduction is also associated with gradual dilatation internal os and various biochemical , mechanical changes in matrix can lead mid trimester pregnancy loss or preterm labour. This case report on Dichorionic Diamniotic incompetence which rescue cerclage was performed along judicious use tocolysis vagi...

INTRODUCTION This study investigates patterns of intertwin size discordance in dichorionic diamniotic (DCDA) and monochorionic diamniotic (MCDA) twin pregnancies. MATERIAL AND METHODS Ultrasound measurements of twin pregnancies, from 14 weeks to term, were collected by 9 hospitals over a 10-year period. This analysis considers the modelled and observed levels of discordance in abdominal circu...

BACKGROUND We examined the perinatal outcomes in cases of at least one fetal demise in monochorionic and diamniotic twin pregnancies. METHODS We reviewed the obstetric records of all Japanese twin pregnancies managed beyond 9 weeks' gestation at Japanese Red Cross Katsushika Maternity Hospital between 2008 and 2014. RESULTS The incidence in the monochorionic twin pregnancies was significant...
