  • Title: Bifrontal approach for clip ligation of bilateral ethmoidal dural arteriovenous fistulas: operative video.
    Author: Cole TS, Gandhi S, Mascitelli JR, Hardesty D, Cavallo C, Lawton MT.
    Journal: Neurosurg Focus; 2019 Apr 01; 46(Suppl_2):V14. PubMed ID: 30939440.
    Abstract:
    Venous interruption through surgical clip ligation is the gold standard treatment for ethmoidal dural arteriovenous fistula (e-dAVF). Their malignant natural history is attributable to the higher predilection for retrograde cortical venous drainage. This video illustrates an e-dAVF in a 70-year-old man with progressive tinnitus and headache. Angiogram revealed bilateral e-dAVFs (Borden III-Cognard III) with one fistula draining into cavernous sinus and another to the sagittal sinus. A bifrontal craniotomy was utilized for venous interruption of both e-dAVFs. Postoperative angiography confirmed curative obliteration with no postoperative anosmia. Bilateral e-dAVFs are rare but can be safely treated simultaneously through a single craniotomy.The video can be found here: https://youtu.be/666edwKHGKc.
