Classification and radiographic features of uterine malformations: hysterosalpingographic study.

A series of 13470 hysterosalpingographic investigations demonstrated congenital uterine malformations in 1160 cases (8.6%). Uterus arcuatus and uterine hypoplasia, the latter ranking as a malformation on embryological grounds, together accounted for two-thirds of the cases, uterus unicornis unicollis and uterus bicornis unicollis together for over a quarter and the others, uterine didelphys, uterus bicornis bicollis and uterus septus/subseptus, for much smaller percentages. Each malformation is described and illustrated by typical hysterosalpingograms. In addition to its decisive importance in diagnosis, hysterosalpingography it also valuable in planning surgical correction in many cases.
