title: Acquired uterine arteriovenous malformation developing in retained products of conception: a diagnostic dilemma.
abstract: Abnormal uterine bleeding in the postabortal period requires meticulous diagnostic work-up to decide proper management. Imaging modalities including Doppler sonography and magnetic resonance imaging in concert with clinical and laboratory findings are useful to narrow the differential diagnoses but are not definitive. Presence of increased uterine vascularity and arteriovenous shunting is non-specific and can be detected in a variety of conditions including retained trophoblastic tissue, gestational trophoblastic disease, arteriovenous malformation (AVM), placental polyp and vascular neoplasm. We present here a case of a multiparous woman with unexplained postabortal bleeding posing a diagnostic challenge. Excluding the possibility of AVM before attempting dilatation and curettage in such a clinical scenario is crucial to prevent catastrophic bleeding.
