Fertility after treatment of Asherman’s syndrome stage 3 and 4

Study objectiveTo evaluate the efficacy of hysteroscopic adhesiolysis and subsequent fertility in patients with adhesions stage 3 and 4.DesignA retrospective cohort study (Canadian Task Force classification II-2).SettingA tertiary referral center for hysteroscopic surgery.PatientsSeventy-one patients with intrauterine permanent adhesions.InterventionsHysteroscopic surgery with monopolar energy (n = 31) or bipolar energy (n = 40). Uterine cavity with at least one free ostial area was restored after one (n = 31), two (n = 20), three (n = 15), or four or more (n = 5) surgical proceduresResultsSixty-four patients were followed. Evaluation of the uterine cavity after surgery has been performed by hysteroscopy for all the patients. All patients had resumption of menses, except for two patients with a history of uterine artery embolization. Pregnancy index rate after the procedure was 28 (43.8%) of 64, and the live birth rate was 21 (32.8%) of 64. In patients 35 years of age or younger, 20 of 30 (66.6%) conceived compared with 8 of 34 (23.5%) in patients older than 35 years (p = .01). Three patients had either hysterectomy (n = 2) or hypogastric arteries ligation for placenta accreta with uneventful postoperative course.ConclusionsHysteroscopic adhesiolysis can be performed for severe adhesions stage 3 and 4 with safety and efficacy. Age is the main predictive factors of success: the pregnancies were at risk of abnormal placentation.
