[The prognosis of sonographically early diagnosed twin pregnancies]
We retrospectively analyzed 95 intact twin pregnancies (GG) only diagnosed by sonography during the period 1977-1987: 48 GG were registered up to the 10th week of pregnancy (G 10), 90 between the 11th and the 16th week of pregnancy inclusive (G 16). In the group G 10, this spontaneous fetal loss, including the perinatal mortality amounted to 10.9% (10 of 92) twins (GF). In 5 cases from this group, a previously vital twin was lost before the 10th week. The loss in group G 16, including the perinatal mortality, was 9.7% (17 of 176 twins GF). An early or late abortion occurred in 6 cases (6.8%) and dies perinatally in this group. 82 GG were carried out to full term. 38 women (46.3%) had premature births, 12 pregnancies (12.6%) ended before the 34th week of pregnancy. The perinatal mortality rate amounted to 3.0% (5 GF), 4 (2.3%) of 172 GF had serious malformations. In 6 GG (7.4%) the weight of the twins differed more than 25%.
