  • Title: Endovascular treatment of complex dural arteriovenous fistula using the dual-microcatheter technique.
    Author: Levitt MR, Osbun JW, Nerva JD, Kim LJ.
    Journal: Neurosurg Focus; 2014 Jul; 37(1 Suppl):1. PubMed ID: 24983721.
    Abstract:
    A 71-year-old woman presented with headache and dilated vessels on CTA. Angiography demonstrated a complex dural arteriovenous fistula with retrograde cortical venous hypertension, supplied by branches of internal and external carotids bilaterally into a fistulous pouch paralleling the left transverse and sigmoid sinuses, which was occluded at the jugular bulb. The patient refused treatment and was lost to follow-up, returning with sudden confusion and hemianopsia from left temporo-occipital hemorrhage. Transvenous endovascular embolization was performed using the dual-microcatheter technique with a combination of coiling and Onyx copolymer, completely occluding the sinus and fistula while preserving normal venous drainage.
