Nj. Sebire et al., THE PREVALENCE AND CONSEQUENCES OF MISSED ABORTION IN TWIN PREGNANCIES AT 10 TO 14 WEEKS OF GESTATION, British journal of obstetrics and gynaecology, 104(7), 1997, pp. 847-848
In singleton pregnancies at 10 to 14 weeks of gestation the prevalence
of missed abortion is about 2%. In an ultrasound screening study at 1
0 to 14 weeks of gestation involving 492 twin pregnancies the prevalen
ce of missed abortion was about twice as high as in singletons. The ri
sk of subsequent miscarriage in twin pregnancies with one missed abort
ion was about ten times higher than in normal twin pregnancies. These
findings may have important implications both in terms of counselling
and for future research into the causes of miscarriage.
