Objective: Uterine arteriovenous malformation (AVM) is a rare condition and can be life-threatening if not managed properly. We report a case that was diagnosed by typical ultrasound imaging and treated successfully with uterine arterial embolization. Case Report: A 28-year-old female, gravida 4, para 3, abortus 1, presented with massive vaginal bleeding 19 days after a termination of pregnancy due to fetal anomaly. After a dilatation and curettage 3 years previously, typical ultrasound image

Conclusion: AVM can be diagnosed at an early stage with the aid of history taking and ultrasound. Percutaneous embolotherapy is a safe and effective treatment for AVM, especially when fertility preservation is desired. [Taiwanese J Obstet Gynecol 2007;46(1):60-63] A.C. Lin, et al Figure 4. Pelvic angiogram obtained after embolization shows no residual opacification and complete embolization of the arteriovenous malformation.
