The septate uterus is the most common congenital uterine malformation resulting from a resorption defect of the inter-mullerian septum. It is frequently associated with conception abnormalities such as early recurrent spontaneous miscarriage (FCS) and late recurrent miscarriage (FCT) but also with fertility abnormalities, without a clear mechanism. The imaging techniques used to diagnose a septate uterus are based on : Endo-vaginal ultrasound, diagnostic hysteroscopy and IRM pelvic . Surgical treatment is based on septum sectioning which is a minimally invasive surgical technique with low risk of complications. This septal section significantly improves the obstetrical prognosis in women with a desire for pregnancy.
