OBJECTIVE: This study aimed to determine the effect of twin pregnancy chorionic properties on pregnancy complications and fetal outcomes. MATERIALS AND METHODS: A total of 559 subjects with gemellary pregnancy were included in the retrospective analysis, and clinical data, such as monitoring data during pregnancy and maternal and fetal outcomes, were recorded in detail. Based on the ultrasound results and methods of the postpartum pathologic examination of the placental membranes, the subjects were divided into the twin group with monochorionic diamnion (MCDA group, n = 198) and twin group with dichorionic diamnion (DCDA group, n = 361)...

OBJECTIVES: To describe the perinatal outcomes of type II and III selective fetal growth restriction (sFGR) in monochorionic-diamniotic (MCDA) twin pregnancies treated with expectant management or laser ablation of placental vessels (LAPV). METHODS: Retrospective analysis of cases of sFGR that received expectant management (type II, n=6; type III, n=22) or LAPV (type II, n=30; type III, n=9). The main outcomes were gestational age at delivery and survival rate. RESULTS: The smaller fetus presented an absent/reversed "a" wave in the ductus venosus (arAWDV) in all LAPV cases, while none of the expectant management cases presented arAWDV...

When to deliver the monochorionic diamniotic (MCDA) twins with specific cord patterns? Although there is no clear evidence supporting an earlier delivery (before 36 weeks of gestation) in MCDA twins, an earlier delivery might prevent intrauterine death or neuromorbidity in MCDA twins with specific cord patterns.

OBJECTIVE: The aim of this study was to investigate the association between abnormal cord insertion and the development of the twin-specific complications, including birthweight discordance, selective fetal growth restriction (sFGR) and twin-to-twin transfusion syndrome (TTTS). METHODS: A single-center cohort study of twin pregnancies. Abnormal cord insertion was defined as either marginal (cord attachment site less than 2cm to the nearest margin of the placental disc) or velamentous (when the umbilical cord was attached to the membrane before reaching the placental disc with clear evidence of vessels traversing the membranes to connect with the placental disc), as described in placental pathology reports...

Recent studies have demonstrated an association between congenital Zika virus (ZIKV) infection and microcephaly; however, to date, there have been no reports on the consequences of ZIKV infection on fetuses in twin pregnancies. Herein, we reported on the first case of a monochorionic diamniotic (MCDA) twin pregnancy having ZIKV-related microcephaly. Our findings suggested that, in an MCDA twin pregnancy, the ZIKV may cause infection in both fetuses, resulting in severe abnormalities in the central nervous system due to neural cell destruction and the disruption of the normal development processes of the brain...

BACKGROUND: Chronic hypertension in adults causes arterial lengthening in major arteries, but the effects of early fetal hypertension on the twin-twin transfusion syndrome recipient's vascular architecture remains unknown. OBJECTIVE: We hypothesize that arterial cord redundancy is related to recipient hypertension and subsequent heart failure. Our objectives were to: (1) establish a 3-dimensional color Doppler ultrasound method of measuring umbilical arterial length relative to its corresponding venous segment in the umbilical cord using artery vein angle; (2) compare recipient artery vein angle to gestational age-matched controls; and (3) test the association of artery vein angle with recipient heart failure...

INTRODUCTION: Nuclear factor, erythroid 2 like 2 (NFE2L2) is an important transcription factor that protects cells from oxidative stress (OS). NFE2L2 deficiency in placentas is associated with pregnancy complications. We have demonstrated that elevated OS existed in placental shares of the smaller fetus in selective intrauterine growth restriction (sIUGR); however, the role of NFE2L2 in the development of sIUGR remains unknown. In this study, we examined the levels of NFE2L2 and heme oxygenase 1 (HMOX1), a major antioxidant regulated by NFE2L2, in sIUGR placentas...
