Fetal cholelithiasis is a rare finding during a third-trimester ultrasound with an average incidence rate of 0.07-1.15%. We report a case of fetal cholelithiasis in twins, observed in a patient with monochorionic diamniotic twin pregnancy hospitalized at our unit for signs of premature labor. We present the outcome of the 2 neonates with a clinical and sonographic follow-up. In addition, we offer a comprehensive review of the literature available to date.

The incidence of monochorionic gestation is increased eight-fold following assisted reproductive techniques [1]. Monochorionic triplet pregnancies are rare, occurring in 1 in 45 500 deliveries [2], and are associated with high mortality and morbidity. Both conjoined twins and the twin reversed arterial perfusion (TRAP) sequence are unique complications of monochorionic pregnancy. The present study describes transvaginal ultrasonography findings from a monochorionic diamniotic triplet pregnancy at 10 weeks of gestation following double embryo transfer; a TRAP sequence, with a pair of conjoined twins as a "pump" fetus was identified...

BACKGROUND: Twin pregnancies are at higher risks of velamentous cord insertion (VCI) and vasa previa. In-vitro fertilization (IVF) is an additional risk factor of abnormal cord insertion and thus the incidence of vasa previa is likely to increase over the next decades. OBJECTIVE: To evaluate the role of ultrasound imaging in optimizing the management of twins diagnosed with vasa previa antenatally. STUDY DESIGN: We searched our database for twin pregnancies diagnosed with vasa previa and managed antenatally using measurements of cervical length (CL) and performed a systematic review of articles which correlated prenatal diagnosis of vasa previa in twins and pregnancy outcome...

BACKGROUND: Single intrauterine death (sIUD) in twin pregnancies is associated with a significant risk of co-twin demise and preterm birth (PTB), especially in monochorionic (MC) twins. However, it is yet to be established whether the gestational age at loss may influence the pregnancy outcome. The aim of this study was to explore the risk of PTB according to the gestational age at the diagnosis of sIUD. METHODS: A cohort study of all twin pregnancies from a large regional network of 9 hospitals over a ten-year period...

Monochorionic monoamniotic (MM) twin pregnancy carries a high risk of intrauterine fetal death (IUFD). Single IUFD in an MM twin pregnancy prior to 22 weeks of gestation has been reported to be strongly correlated with double twin demise. To our knowledge, there are no case reports on the natural course of a surviving co-twin in an MM twin pregnancy resulting in live birth after a single IUFD prior to 22 weeks of gestation. Here, we report a case of a surviving co-twin, after a single IUFD at 21 weeks of gestation in a MM twin pregnancy, with an antenatal diagnosis of renal hypoplasia and severe neurological damage leading to porencephaly, and live birth at 36 weeks of gestation...

Twin-to-twin transfusion syndrome (TTTS) complicates 10% of monochorionic twin pregnancies and it is consequence of an unbalanced exchange blood through the vascular anastomoses at placental surface. If not treated, mortality rates in TTTS may be as high as 80 to 100%. Laser photocoagulation of the placental anastomoses is the first treatment option, however in some situations the damage of the placenta in the postpartum may become difficult the residual anastomoses identification. We propose a new non-invasive technique to assess the residual anastomoses using computed tomography (CT) scan data to generate a three-dimensional (3D) virtual placentoscopy...

Pentalogy of Fallot is a cyanotic congenital heart disease that has guarded prognosis without surgical intervention in infancy. Women with uncorrected defects rarely survive into childbearing age and pregnancy in this group is associated with a high rate of perinatal loss. Physiological cardiovascular changes in pregnancy can lead to maternal haemodynamic instability with subsequent adverse cardiac sequelae with or without fetal decompensation. Optimum management and pregnancy outcomes in mother with uncorrected Pentalogy of Fallot and twin pregnancy have not been described in the literature...

BACKGROUND: Twin gestations are at significantly higher risk of fetal growth restriction in comparison with singletons. Using fetal biometric charts customized for obstetrical and parental characteristics may facilitate an accurate assessment of fetal growth. OBJECTIVE: The objective of the study was to construct reference charts for the gestation of fetal biometric parameters stratified by chorionicity and customized for obstetrical and parental characteristics...

The early diagnosis of the Twin-To-Twin transfusion syndrome (TTTS) carries benefits of the better survivor for the fetus-donor; but at the same time there are obvious practical impediments to diagnose the condition earlier in the course of a pregnancy. That's why this particular problem in practical medicine requires in depth investigation to clarify casual factors, and specify tactical approach to the prospective patients which in turn will lead to prevention of the fetal death and damage and improvement of fetal survivor in any form of TTTS...

BACKGROUND AND AIMS: Twin pregnancy with monochorionic placenta may be associated with arteriovenous vascular anastomosis of the placental vessels resulting in twin-to-twin transfusion syndrome (TTTS) and twin reversed arterial perfusion syndrome (TRAP). Foetoscopic LASER ablation (FLA) is the treatment of choice in reducing foetal mortality related to this. METHODS: A retrospective review of medical records of 41 FLA procedures for TTTS and TRAP were analysed for anaesthetic management...

A monochorionic-diamniotic twin baby presented with intrauterine growth restriction and anuria. The baby was found to have bladder agenesis, a pelvic dysplastic horseshoe kidney, vertebral anomalies, a ventricular septal defect and facial dysmorphisms. It was surprising to find no abnormalities in amniotic fluid indices prenatally, suggesting the possibility of urine output that declined as the pregnancy proceeded. Some degree of twin-to-twin transfusion of amniotic fluid was also possible, which could have rescued the oligohydramnios known to be associated with kidney and urinary tract abnormalities...

The aim of this study was to determine the effects of intrauterine environment on the magnitude of intrapair differences in six somatic traits of monozygotic (MZ) and dizygotic (DZ) twins (1,263 pairs; 424 MZ twins and 839 DZ twins). Differences in intrauterine environments of MZ twins enforced division of the research material into four groups: (1) MZ-MC-TTTS - MZ twins from monochorionic (MC) pregnancies with twin-to-twin transfusion syndrome (TTTS), (2) MZ-MC (without TTTS)-MZ twins from MC pregnancies without TTTS, (3) MZ-DC-MZ twins from dichorionic (DC) pregnancies, and (4) DZ-DZ twins...

OBJECTIVE: To explore the outcome of monochorionic (MC) twin pregnancies affected by selective intra-uterine growth restriction (sIUGR) according to the umbilical artery Doppler pattern of the smaller twin. METHODS: Medline, Embase, Cinhal and ClinicalTrials.gov databases (2000-2016) were searched. sIUGR was defined as the presence of one twin with estimated fetal weight and/or abdominal circumference less than 10(th) or 5(th) percentile and classified according to the umbilical artery Doppler flow pattern of the smaller twin (type I: persistently positive, type II: persistently absent/reversed, type III: intermittently absent/reversed)...

The article describes an acardiac fetus in a patient with monochorionic diamniotic twin pregnancy with reversed arterial perfusion syndrome at 30 weeks' gestation. It gives postmortem fetal computed tomographic and pathoanatomic data. Microarray of acardiac fetal tissues revealed that there was deletion of chromosome 19 - arr [hg19] 19p13.3q11 (260,911-23,005,001) x1; size, 23 Mbp; the signal level in about 30% of fetal tissue cells containing deletion.
