Congenital uterine arteriovenous malformation presenting as vaginal bleeding following vaginal delivery in a 23-year-old woman: A case report

Congenital uterine arteriovenous malformations (AVMs) are an uncommon cause of vaginal bleeding in women of reproductive age. In the medical literature, there are few reports of congenital uterine AVMs. This report describes a 23-year-old woman who presented with intermittent vaginal bleeding following a vaginal delivery two years prior. Initially, a molar pregnancy was suspected, but further assessment with magnetic resonance imaging revealed a diagnosis of right uterine AVM. The patient underwent uterine artery embolization, which was repeated three months later. At two-year follow-up, the patient remained free of symptoms. This case highlights the importance of considering congenital uterine AVM as a potential cause of vaginal bleeding and emphasizes the need for clinical examination and radiologic investigations to establish an accurate diagnosis. Treatment depends on disease severity, comorbidities, patient age, and fertility desires.
