title: Ultrasound evidence of early pregnancy failure in patients with multiple conceptions.
abstract: I report a review of 1500 pregnant patients: 30 of them (or 1 in 50) were thought to have multiple pregnancies when examined by ultrasound in the first trimester. Only 14 of the 30 patients (46.7 per cent) produced live infants: 13 twins and one set of triplets. Twelve (40 per cent) had bleeding in early pregnancy and 11 of these had a spontaneous abortion. Five of seven patients found to have a normal pregnancy and a coexistent blighted ovum, ultimately delivered a single live infant.
