OBJECTIVE: Short cervical length (CL) in mid-gestation is considered predictive of spontaneous preterm birth (PTB). The medical literature suggests 20 mm as the cut-off for high risk in twin pregnancies. Our objective was to assess the predictive value of CL for spontaneous PTB < 32 weeks' gestation in twin pregnancies and to calculate the cut-off point with the best sensitivity and specificity. METHODS: This was a single-center retrospective cohort study of women in whom CL had been measured by transvaginal ultrasound at 18-23 weeks' gestation...

The number of multiple gestations has increased over the last several decades and preterm birth is one of the leading causes of perinatal morbidity and mortality for these pregnancies. While screening and treatment strategies have achieved moderate success in singleton gestations, screening strategies are less effective in multiple gestations. In addition, to date no intervention aimed at preventing preterm birth has been conclusively shown to either prolong gestation or improve neonatal outcomes for multiple gestations...

Monoamniotic twins comprise a rare but important subset of twins at risk of unique and serious complications, placing them at the highest risk of perinatal mortality of all twin gestations. In addition to risks faced by all twins (prematurity, selective growth restriction), all monochorionic twins (twin-twin transfusion syndrome), and all monozygotic twins (congenital anomalies), monoamniotic twins face the unique risk of cord entanglement. Accordingly, early diagnosis, screening for fetal anomalies, surveillance for twin-twin transfusion syndrome, decisions related to monitoring after viability, and timing and route of delivery are all critical...

OBJECTIVE: The purpose of this study was to investigate the use of vaginal progesterone for the prevention of preterm delivery in twin pregnancies. STUDY DESIGN: We conducted a prospective, randomized, double-blind, placebo-controlled trial that involved 390 naturally conceived twin pregnancies among mothers with no history of preterm delivery who were receiving antenatal care at a single center. Women with twin pregnancies between 18 and 21 weeks and 6 days' gestation were assigned randomly to daily vaginal progesterone (200 mg) or placebo ovules until 34 weeks and 6 days' gestation...

OBJECTIVE: We studied whether abnormal umbilical artery (UA) Doppler flow velocity waveforms occur with higher frequency in monochorionic diamniotic (MCDA) twin gestations with discordant fetal growth and whether this impacted neonatal outcome. STUDY DESIGN: We performed a retrospective study of MCDA twin pairs. We collected data from an electronic medical record. We classified pregnancies as discordant if there was at least 20% birth weight discordance. Abnormal UA Doppler velocity waveforms included absent or reversed end diastolic flow...

OBJECTIVE: The aim of this study was to quantify the risk of brain abnormalities in single-twin demise of monochorionic pregnancies and to describe the type of brain injuries using ultrasound and in utero magnetic resonance (iuMR) imaging. METHODS: Monochorionic twin pregnancies complicated by the demise of one twin referred between 2004 and 2013 were reviewed. Ultrasound was performed in a tertiary centre prior to iuMR. The cases were subdivided into those associated with co-twin loss following fetoscopic laser ablative treatment for twin-twin transfusion syndrome (TTTS) and those associated with spontaneous fetal demise...

OBJECTIVE: Impaired fetal growth might be better evaluated in twin pregnancies by assessing the intertwin discordance rather than the individual fetal size. The aim of this study was to investigate the prediction of perinatal loss in twin pregnancy using discordance in fetal biometry and Doppler. STUDY DESIGN: This was a retrospective cohort study in a tertiary referral center. The estimated fetal weight (EFW), umbilical artery (UA) pulsatility index (PI), middle cerebral artery (MCA) PI, cerebroplacental ratio (CPR), and their discordance recorded at the last ultrasound assessment before delivery or demise of one or both fetuses were converted into centiles or multiples of the median (MoM)...

The objective of this study is to evaluate neonatal and maternal outcomes of multiple gestations undergoing delayed-interval delivery at a single institution. A 10-year retrospective review of medical records of patients followed by a Maternal-Fetal Medicine practice in a university-based setting was performed. Patients met criteria for inclusion if a single fetus was delivered spontaneously between 16 and 28 weeks of gestation and a planned attempt was made to prolong the gestation for the remaining fetus(es)...

AIM: The aim of study is to compare maternal and fetal outcomes of pregnancies in which cerclage was placed following the loss of first fetus with those without cerclage placement in multiple pregnancies for delayed interval delivery. METHODS: Records of pregnancies in which the first fetus was lost between 13-26 weeks and delayed delivery experienced for retained fetus(es), were collected retrospectively. A total of 20 patients including 11 twins, seven triplets and two quadruplets were evaluated...
