Clinical Conundrum: A 39-Year-Old With Chronic Retained Products of Conception and Concurrent Uterine Arteriovenous Malformation.

A 39-year-old woman presented with bleeding 4 months after a surgical termination of pregnancy. Persistent beta-human chorionic gonadotropin levels were suggestive of retained products of conception (RPOC). However, multimodal imaging revealed a concurrent uterine arteriovenous malformation (AVM). Although most stable AVMs can be managed conservatively, the need for surgical management of chronic RPOC and consequential hemorrhage risk complicates this approach. Patient-determined management prioritized blood conservation while minimizing risks to fertility. This case is discussed with respect to the rare concurrent existence of RPOC and AVM. Little is known regarding the optimal tandem therapeutic approach. As depicted, successful treatment requires careful diagnostic workup and a multidisciplinary approach.
