WomenвЂ™s parity is also a condition with high influence in mode of delivery in a twin pregnancy, as nulliparous usually result in less success when attempting a vaginal delivery. The most important factors to be considered on deciding the delivery mode are the fetus presentation, especially the first twin, fetal weight, weight difference between the fetuses, gestational weight and maternal clinical conditions. The mode of delivery in twin pregnancy depends on multiple factors and is very controversial in the literature. This fact is justified by the high rate of perinatal mortality in the third trimester (30вЂ“70%) and has as main motive the umbilical cords entanglement in the same amniotic chamber. On the other hand, in monoamniotic pregnancies, most specialized centers in the world recommend delivery between 32 and 34В weeks. It is clear that in cases of Twin-Twin Transfusion Syndrome, most of deliveries are performed earlier and this depends on the degree of complication that is present. However, others delegate delivery at 32В weeks of gestation. ACOG suggests delivery of monochorionic twins between 34В +В 0 to 37В +В 6В weeks of gestation and the North American Fetal Therapy Network suggests delivery at 36В +В 0 to 37В +В 6В weeks of gestation. There is still a lot of divergence between medical societies for the correct time of delivery. This may be the point of balance between the already reduced risk of prematurity and the risk of fetal death. Most specialists in large reference centers recommend delivery of monochorionic/diamniotic twins between 36В +В 0 and 36В +В 6В weeks. Just like DC gestations, there are no high-quality studies to respond with great certainty the right time for terminate monochorionic pregnancies. perinatal deaths, which was not significant. The same review showed that monochorionic pregnancies beyond 34В weeks (13 studies, 2149 pregnancies), had a tendency for an increase in stillbirths compared to neonatal deaths after 36В weeks, with an additional 2. Time of delivery in monochorionic pregnancies This group recommended increased fetal surveillance after 34В weeks of gestation in multiple pregnancies.

The risk of child death after delivery gradually declined as pregnancies neared full term. This risk was higher between 34 and 37В weeks of gestation in triplet pregnancies. The authors concluded that fetal vitality control was not sufficient to prevent adverse events and delivery should be planned up to the 37th week for MC.ДЄ study with 94,170 multiple deliveries showed that the risk of fetal death increased significantly between 37 and 38В weeks of gestation in twin pregnancies. The risk of uterine death was significantly higher in MC than in DC (hazard ratio 8.8, 95% CI 2.7вЂ“28.9), and in most cases no change in fetal status was observed. ДЄ large Dutch cohort with 1407 multiple pregnancies showed that after 32В weeksвЂ™ gestation, mortality was 11.6% in MC and 5% in dichorionic (DC). It is possible that the single placental mass shared between pairs originates from an imbalance in placental anastomoses, may be overloaded in the third trimester. The monochorionic (MC) pregnancies present a higher incidence of perinatal mortality, higher admission in neonatal intensive care unit and low birth weight. In fact, this risk is related to chorionicity. This is mainly due to prematurity, complications close to delivery, and placental insufficiency. Multiple pregnancies have high rates of mortality and morbidity when compared to single pregnancies. Risk of fetal death in the third trimester for twin pregnancies
