The extended use of assisted reproductive technologies is increasing the heterotopic pregnancies, leading to a potentially dangerous condition for the intrauterine pregnancy and the mother. We report a case of unruptured heterotopic pregnancy following IVF-ET at 6 weeks of gestation and the patient was treated with salpingostomy under spinal anesthesia. ...

The incidence of twin gestation has increased markedly over the past decades, mostly because of increased use of assisted reproductive technologies. Twin pregnancies are at increased risk of preterm delivery (i.e. birth before 37 weeks of gestation). Multiple gestations therefore account for 2-3% of all pregnancies but constitute at least ...

Timing of delivery of twins should be decided when the benefit of prolonging the pregnancy outweighs the risk of stillbirth. Perinatal mortality of singletons is increased significantly after 42 weeks, whereas perinatal mortality in twins starts to increase significantly after 37 weeks. Recent, large cohort studies have showed significantly higher ...

Single-twin demise can pose substantial risks for the surviving co-twin, including increased risk of fetal loss, preterm delivery, neurovascular injury, and end-organ damage. In this chapter, we summarise recently published research on the causes of single twin demise, the pathophysiology of injury to the surviving co-twin, and the evidence for ...

Objectives- The purpose of this study was to test the hypothesis that using the formula of a prolate ellipsoid to estimate parabiotic twin mass correlates better with findings of pump twin compromise than using the sonographic method of Moore et al (Am J Obstet Gynecol 1990; 163:907-912). Methods- A 10-year ...

Twin partial hydatidiform molar pregnancy with a viable fetus is an uncommon occurrence. Presentations of molar pregnancies include vaginal bleeding, unusually elevated β-human chorionic gonadotropin level, and preeclampsia. Previous descriptions of twin molar and fetus pregnancies in the literature have been described in the outpatient obstetric setting. We present a ...

Ultrasound determination of chorionicity is most reliable before 14 weeks and subsequently reduces in accuracy with advancing gestation. The aim of this study was to evaluate the accuracy of chorionicity determination in a birth cohort of twin pregnancies. Antenatal ultrasound determination of chorionicity in twin pregnancy was undertaken at suboptimal ...

Reduction of fetal number has been offered in high order multiple gestations but is still controversial in triplets. Since recent advances in neonatal and obstetric care have greatly improved outcome, the benefits of multifetal pregnancy reduction (MFPR) may no longer exist in triplet gestations. To evaluate if fetal reduction of ...

Twin birth is associated with a higher risk of adverse perinatal outcomes than singleton birth. It is unclear whether planned cesarean section results in a lower risk of adverse outcomes than planned vaginal delivery in twin pregnancy. We randomly assigned women between 32 weeks 0 days and 38 weeks 6 ...

The rate of multiple pregnancies is showing a significant increase in Western countries. Twin gestations should be considered a high-risk condition because they are responsible for a disproportionate amount of overall perinatal morbidity and mortality. We used a specialised ultrasound protocol based on chorionicity to monitor 44 twin pregnancies (61% ...

An understanding of the normal behaviour of biochemical markers in twin pregnancies is necessary in order to offer prenatal screening to this sub group. This study investigates the levels of first trimester maternal serum placental growth factor (PlGF) in twin and singleton pregnancies. PlGF concentrations were measured by an automated ...

Maternal stress during pregnancy is associated with a modestly increased risk of fetal growth restriction and pre-eclampsia. Since placental abruption shares similar pathophysiological mechanisms and risk factors with fetal growth restriction and pre-eclampsia, we hypothesized that maternal stress may be implicated in abruption risk. We investigated the association between maternal ...
