Novel endovascular techniques to control in-outflow with dual approach for large pelvic arteriovenous malformation

Here, we present the case of a 51-year-old woman with high-output congestive heart failure caused by a large pelvic arteriovenous malformation. Endovascular treatment that combined arterial nidus embolization with n-butyl 2-cyanoacrylate, coil embolization of the venous component, and balloon-occluded retrograde transvenous obliteration was performed. A promising therapeutic outcome was achieved without recurrence of symptoms over a 3-year period. The combination of these techniques to control arterial inflow and venous outflow is a novel method for the treatment of large pelvic arteriovenous malformation.
