Endovascular management of a pelvic arteriovenous malformation

Aneurysmal pelvic arteriovenous malformations in male patients are exceptionally rare. Upon spontaneous or traumatic rupture, these aneurysms can cause severe hemorrhage and are often associated with high mortality. Given that most intact aneurysms are found after symptomatic presentation, other case reports have detailed an approach for elective endovascular treatment for concomitant arterial and venous embolization. We describe an incidental discovery of a 7-cm-high flow pelvic aneurysmal arteriovenous malformation and successful endovascular treatment strategy through staged arterial and venous embolization, reducing the risk of rupture owing to high flow collateralization.
