Hiatal hernias are usually sporadic and uncommon, requiring a high index of suspicion. Preterm monochorionic-monoamniotic twins with recurrent emesis had inconclusive radiographs contrast study consistent hiatal hernia. Genetic testing was performed due to concerns for familial inheritance. Early diagnosis treatment essential prevent complications.

I n the past 20 years, advancing maternal age and greater reliance on assisted-conception techniques have dramatically increased the incidence of multiple births, including monochorionic twins (see Glossary) [1,2]. Concomitantly, there have been advances in our understanding of these high-risk pregnancies. The offspring of multiple pregnancies are at greater risk for adverse perinatal outcomes ...

OBJECTIVE Discordance in nuchal translucency measurements in monochorionic diamniotic twin pregnancies was assessed as predictor of Twin-to-Twin Transfusion Syndrome. STUDY DESIGN A total of 61 monochorionic diamniotic twins were enrolled. Nuchal translucency (NT) and crown-rump-length (CRL) discordance was calculated as the percentage of delta NT and CRL (absolute difference NT/CRL fetus 1 a...

Background  Monochorionic-triamniotic pregnancies are rare and fraught with complications. Case  A case of monochorionic-triamniotic triplet pregnancy complicated by twin reversed arterial perfusion (TRAP) sequence is presented. The patient declined termination or selective fetal reduction. Triplet C was acardiac. At 24 weeks, triplet B developed polyhydramnios. At 30 weeks, polyhydramnios was ...

OBJECTIVE To describe a new technique for embryo reduction (ER) in dichorionic triplet (DCT) pregnancies. METHODS In 22 DCT pregnancies, ER to dichorionic twins was carried out at 11.3-13.9 weeks' gestation by ultrasound-guided laser ablation of the pelvic vessels of one of the monochorionic twins. RESULTS Intrafetal laser was successfully carried out in all cases, but ultrasound examinatio...

This study was conducted to determine the incidence of cerebral injury as detected by postnatal brain scan in monochorionic twins with selective intrauterine growth restriction. Having excluded cases complicated with twin-to-twin transfusion syndrome and one co-twin suffering intrauterine fetal death, a total of 73 monochorionic twin pregnancies divided into absence (group I, n = 46) or presenc...

OBJECTIVE The objective of the study was to construct an ultrasound-based estimated fetal weight-for-gestational-age reference for twin fetuses, stratified by chorionicity. STUDY DESIGN We performed a retrospective cohort study of live-born nonanomalous twins delivered longer than 34 weeks at the Royal Victoria Hospital (Montreal, Canada). Fetal weight was estimated using ultrasound biometric...

OBJECTIVE To compare the fetal loss rate of monochorionic (MC) twin pregnancies according to their amnionicity. METHODS A retrospective review of all MC pregnancy outcomes in a tertiary centre. Pregnancy outcomes were compared for monochorionic monoamniotic (MCMA) versus monochorionic diamniotic (MCDA) pregnancies. RESULTS 29 MCMA and 117 MCDA twin pregnancies were identified. The overall f...

Fetus- in- fetu (FIF), is a rare congenital anomaly that occurs due to malformed fetus growing inside the twin. It occurs due to the aberration in the diamniotic monochorionic monozygotic twinning with unequal division of inner cell mass of blastocyst leading to inclusion of small cell mass inside the developing sister fetus. The most common presentation will be with intra-abdominal mass locat...

OBJECTIVE To study local response to BCG vaccination in twin babies and find out the effect of zygosity andchorionicity on BCG uptake. DESIGN Analytical observational study. SETTING Tertiary hospital. METHODS Twin pairs born in the hospital were evaluated for zygosity and chorionicity. BCG vaccination was given within 48 hours of birth to babies >/=33 weeks of gestation and birth weight >...
