The abnormalities of the presentation in twin pregnancy and perinatal mortality
1Department of Obstetrics and Gynecology, Toldy Ferenc Hospital, Cegléd, Hungary.
The author conducted a retrospective review of the obstetric patient material in his department between January 1, 1975 and December 31, 1992, concerning the clinical implications associated with various lies and presentations of twins. The material included 329 twins (1.07% of all births). Breech, or transverse lies complicated 186 (56.53%) twin gestations. The frequency of premature newborns was among 186 malpresented twin pairs 85 (45.7%) and 101 (54.3%) were mature. The percentage of malpresented twin fetuses increased with maternal age and parity. Abnormal presentations were more frequent (78.49%) among B than A fetuses (54.84%). Perinatal mortality was more frequent among B than A fetuses and more frequent between malpresented twin pairs than the vertex-vertex presented twins.
