In the presence of> 1 fetus in the uterus and multiple pregnancy is present. A Mehrlingsgravidität occurs in 1 in 70 to 80 births. Risk factors Ovarian stimulation reproduction (z. B. In vitro fertilization) are (usually with clomiphene or gonadotropins) Assisted is Preceding multiple pregnancy Advanced maternal age The heavily overstretched uterus tends to premature labor and can thus born prematurely trigger (average gestational age 35 -36 weeks for twins, 32 weeks for triplets and 30 weeks for quadruplets). Irregular fetal position are common. The uterus can contract after the birth of their first child, leading to shear off the placenta and the increased risk for the remaining fetuses in utero. Sometimes the over-stretching of the uterus affects the postnatal contractions and leads maternal bleeding. Complications A multiple pregnancy increases the risk of pre-eclampsia, gestational diabetes, postpartum hemorrhage, cesarean section, premature birth and growth retardation. Some complications develop only multifetalen pregnancies. An example of this is the twin transfusion syndrome (if twins share the same placenta, this syndrome results in vascular exchange between the two, which may lead to an uneven distribution of blood). Prenatal diagnostic sonography A multiple pregnancy is suspected if the uterus appears too large for gestational age; such can be confirmed by an ultrasound. Therapy caesarean section at a given indication A caesarean section is performed for a given indication. A caesarean section is recommended in twins when the presenting twin is in a cephalic. Higher levels of multiple pregnancies are typically delivered by cesarean section regardless of their location.
