Transcatheter and percutaneous procedures for huge pelvic arteriovenous malformations causing high-output heart failure

AbstractWe present the case of a 63-year-old woman presenting with a huge pelvic and retroperitoneal high flow arteriovenous malformation (AVM) causing high-output heart failure, who was treated with combined therapies, including transarterial embolization with n-butyl cyanoacrylate–iodized oil mixture (NBCA–lip) and coils for the right ovarian, both internal iliac, 3rd and 4th lumber arteries, venous sclerotherapy using coils and ethanolamine oleate (EO) for the right ovarian and both internal iliac veins with balloon-occluded retrograde transvenous obliteration technique, and direct percutaneous sclerotherapy using the NBCA–lip and EO for the large nidus of AVM under outflow control using occlusion balloon catheters.
