How risky are twin pregnancies?

As mothers get older and assisted conception becomes more common, the incidence of multiple births--primarily of nonidentical siblings, but also of identical ones--has dramatically increased. Multiple pregnancies are high-risk pregnancies, with preterm delivery and monochorionicity (shared placenta) the major problems. Consequently, efforts are underway to optimize the management of these pregnancies. Nicholas Fisk and colleagues from the Institute of Reproductive and Developmental Biology at Imperial College London are studying records of twin pregnancies and now report results suggesting that uncomplicated twin pregnancies might be more risky than previously thought. Their findings are reported in the June issue of the international open-access journal PLoS Medicine.

While identical (monozygotic) twins are much less common than dizygotic ones, monozygotic twinning events are increased after induced ovulation and in vitro fertilization. Monozygotic twins can be diamniotic dichorionic (two amniotic sacs, two placentas), monoamniotic monochorionic (one amniotic sac, one placenta), or diamniotic monochorionic (two amniotic sacs, one placenta). The last type accounts for approximately two-thirds of all monozygotic twins, and most of those are without overt complications.

Fisk and colleagues have studied records of 151 such seemingly uncomplicated diamniotic monochorionic pregnancies and found a surprisingly high rate of fetal death: ten unexpected intrauterine deaths occurred in seven of the 151 pregnancies with no prior signs of complications. All deaths occurred within two weeks of a normal scan, at a median gestational age of 34 weeks and 1 day.

The authors conclude that "despite intensive fetal surveillance, structurally normal monochorionic diamniotic twin pregnancies are complicated by a high rate of intrauterine death." As the deaths occurred predominantly after 32 weeks' gestation, the authors suggest that the prospe
