title: [Simultaneous pregnancy in each cavity of a bicornuate bicervical uterus with a double vagina].
abstract: A case of twin pregnancy in a bicervical uterus with double vagina is reported. The malformation was known before conception. Caesarean section was performed for premature rupture of the membranes at 34 weeks. This enabled the extraction of two low-birth-weight premature infants free of any particular pathology. The possibility of twin pregnancy in a bicervical bicornuate uterus is 1/1,000,000 and implies the maturation of at least two oocytes. This is a high risk pregnancy. Spontaneous abortions, prematurity (40%), low-birth-weight (25%) are the most notable complications. Although the probability of dynamic dystocia is multiplied by 7, vaginal delivery is not excluded when the obstetric past history is satisfactory and the presentation of both twins cephalic. Caesarean involves hysterotomy of each horn and raises no special technical problems. Double delivery increases the risk of hemorrhage.
