Successful management of abnormal uterine bleeding from uterine arteriovenous malformations with progesterone in postabortal patients.

To study the feasibility of conservative management with progesterone as a treatment option for postabortal patients with uterine arterio-venous malformations (AVMs).This prospective observational study was conducted in the tertiary care teaching hospital over a period of 2 years. Postabortal patients with abnormal uterine bleeding were enrolled. Diagnosis was made by history, clinical and radiological examinations. Oral norethisterone was used (10 mg twice daily for 3 weeks, maximum of three cycles). Descriptive statistics was used to present the data.A total of 30 patients were included. Majority (n = 17) had complete resolution of symptoms after a single 3-week course of progesterone therapy. Rest (n = 13) remained symptomatic and required second course. Of the later, only three remained symptomatic after 2 months, and underwent CT angiography followed by embolization. There was no report of any serious adverse events.Oral norethisterone is a safe, effective and novel oral drug as an alternative to embolization or surgical therapy for patients with postabortal AVM bleed. Larger studies are required to confirm the findings of the present study.
