Blind hemivagina: long-term follow-up and reproductive performance in 42 cases.

Our purpose was to analyse the reproductive performance of women with obstructed hemivagina after surgical treatment. After laparoscopic exploration of 42 cases (mean age: 18 years), didelphic and complete septate uterus were found in 78 and 22% of cases respectively. Resection of vaginal septum and hemihysterectomy with ipsilateral hemicolpectomy were performed in 88% and 12% of the cases, respectively, between 1970 and 1997. Long-term results were assessed by a questionnaire and obtained for 38 patients (mean years after treatment and range: 6.5; 1-23). Dysmenorrhoea and abdominal pain were resolved in 87% and 100% of the cases, respectively. Nine patients experienced 20 pregnancies (13 living children, four early spontaneous abortions, two early terminations and one ectopic pregnancy). Nine offspring (69% of live births) were delivered after 37 weeks. Four patients had four pregnancies ipsilateral to blind hemivagina after vaginal septum resection (two living children, one early spontaneous abortion and one ectopic pregnancy). These results suggest that laparoscopic exploration and resection of vaginal septum are the appropriate treatments for obstructed hemivagina. Subsequent reproductive performance was comparable to that reported following treatment of the associated uterine malformation.
