Transvenous embolization for a huge pelvic arteriovenous malformation associated with prominent outflow veins

We describe the case of an adult female with a huge pelvic arteriovenous malformation (AVM) measuring approx. 8 × 10 × 13 cm, treated via the transvenous approach alone. Management of huge pelvic AVMs is challenging; there is no consensus on a standardized treatment strategy. In our patient, multipl...

Summary:We describe the case of an adult female with a huge pelvic arteriovenous malformation (AVM) measuring approx. 8 × 10 × 13 cm, treated via the transvenous approach alone. Management of huge pelvic AVMs is challenging; there is no consensus on a standardized treatment strategy. In our patient, multiple arterioles shunted to prominently dilated outflow veins. Selective occlusion of prominent outflow veins as close to the nidus as possible achieved significant flow reduction through the nidus. Our treatment may be a safe and acceptable option to control hematuria for huge pelvic AVMs associated with prominent outflow veins, especially when both transarterial embolization and direct puncture are difficult.
