Reproductive outcome of women with rare Müllerian anomaly: report of 2 cases.

Two patients had a rare uterine anomaly characterized by longitudinal vaginal septum, double cervix, and incomplete septum of the uterus with normal fundus. This report is, to our knowledge, the third in the literature. There are some other works describing a similar anomaly, with a complete uterine septum. These cases challenge the classic unidirectional theory of müllerian development and support an alternative bidirectional hypothesis. After definitive diagnosis, the vaginal and uterine septa were successfully resected. Both patients conceived spontaneously and had an uneventful obstetric outcome. Surgical treatment might be an alternative treatment in the case of infertility or recurrent pregnancy loss in patients with such a rare müllerian anomaly. The hysteroscopic uterine reunification should be the preferable surgical method and can improve the poor reproductive outcome.
