    Abstract:
    We report an iatrogenic radial arteriovenous fistula (AVF) in a 74-year-old woman presenting with right radial bruit and pain 8 months after sheath removal for cardiac catheterization. She refused surgical ligation and underwent balloon-assisted direct percutaneous embolization of the draining vein with N-butyl cyanoacrylate (NBCA). Another draining vein that developed immediately after the procedure was conservatively treated with 1 month of continuous band compression. However, its diameter gradually increased and, as the patient desired complete remission, an additional procedure was conducted 2 months after initial treatment. A second balloon-assisted direct percutaneous embolization was performed using a 50 % glucose solution, which resulted in complete resolution. Although surgical repair is considered to be the standard treatment, in patients where surgery is not indicated, endovascular intervention-although complicated-may be an alternative treatment modality.
