Levonorgestrel intrauterine system for the treatment of intermenstrual spotting in patients with previous cesarean delivery scar defect.

Aim: To evaluate the efficacy of levonorgestrel 52 mg intrauterine system for intermenstrual bleeding in patients with previous cesarean delivery scar defects (PCDSs). Methods: The medical records of 28 consecutive patients with previous cesarean delivery scar defect and intermenstrual bleeding who had undergone conservative treatment with levonorgestrel 52 mg intrauterine system were reviewed. The efficacy of treatment and frequency of adverse events were measured retrospectively. Results: After 1 year of treatment, 22 patients (78.6%) reported an improvement in symptoms. The mean duration of menstruation were 18 and 5 days before and after treatment, respectively. No uterine perforations or pelvic inflammatory diseases occurred during or after the insertion procedures. Eighteen (64.3%) patients did not experience any adverse events, and the patients with adverse events reported that they could be managed by adjusting their medications or observation. Conclusion: Levonorgestrel intrauterine system may have a role in the safe and effective management of intermenstrual spotting in patients with PCDSs. [ABSTRACT FROM AUTHOR]
