The Spontaneous Resolution of Trauma-Induced Uterine Arteriovenous Malformation

This paper will describe the case of a woman who presented with a rare condition called uterine arteriovenous malformation (AVM). A uterine AVM represents a connection between veins and arteries in the uterus. Clinicians should always consider this condition for a woman of childbearing age who presents with unexplained vaginal bleeding. In this particular case, a woman had an AVM diagnosed two months following a miscarriage, and a dilation and curettage (D&C), for retained products of conception. This patient presented to the emergency department in apparent distress, although physical examination and initial laboratory values revealed no hemodynamic instability. Ultrasonographic study, followed by an MRI, confirmed the presence of a uterine AVM. Following a consultation with obstetrics and gynecology, she was ultimately referred to an interventional radiologist for a minimally invasive uterine artery embolization. On the day of the procedure, following vascular access, angiography revealed the AVM had spontaneously self-resolved in the interval. In this paper, we will further discuss the possible utility of a repeat ultrasonographic study to reconfirm AVM prior to any surgical procedure, as well as discuss some confounding factors including the use of medroxyprogesterone acetate injections for birth control prior to the formation of the AVM.
