A Case of Transverse Vaginal Septum with Microperforation Which got Pregnant by Intrauterine Insemination / 대한산부인과학회잡지

ABSTRACT

The mullerian ducts join the sinovaginal bulb at a point known as the mullerian tubercle. Canalization of the mullerian tubercle and sinovaginal bulb is necessary to give a normal vaginal lumen. If the area of junction between these structures is not completely canalized, a transverse vaginal septum will occur. This may be partial or complete and generally lies at the junction of the upper third and lower two thirds of the vagina. It occurs in about 1 per 75,000 females. Partial transverse vaginal septa have been reported in diethylstilbestrol (DES)-exposed females. In the prepubertal state, diagnosis is generally not made unless there is the development of a mucocolpos or mucometrium behind the septum. At puberty, however, if the septum is complete, hematocolpos and hematometrium may occur in a fashion similar to that seen in the imperforate hymen, except that there is no bulging at the introitus. The patient with an incomplete transverse septum may bleed somewhat but will still develop hematocolpos and hematometrium over time and may also complain of foul smelling vaginal discharge.
