Bicornuate Uterus with Pregnancy

Incomplete fusion of the Mullerian or paramesonephric ducts results in the most common types of uterine malformation: Uterus didelphys, Uterus bicornis bicollis, uterus bicornis unicollis, uterus subseptae, uterus arcuate,and uterus unicornis. Uterus bicornis bicollis is characterized by double or single vagina, double cervix and two single-horned uteruses which show partial fusing of their muscular walls with duplication running right down to the uterine orifice. These malformations are rare but known to be associated with infertility, spontaneous miscarriages, intrauterine growth restriction, preterm deliveries, pre-term prelabour rupture of membranes, breech presentation and increased rate of caesarean delivery. However, normal reproductive performance has been seen in association with them.
