dc.description.abstract© 2020 Elsevier Inc. Background: The principles of endovascular treatment of bilateral cavernous sinus dural arteriovenous fistula (CS-dAVF) are not well established because of the complexity in the number of fistula tracts and their behavior, which seems to be more aggressive. We aimed to determine an efficient technique for endovascular treatment of bilateral CS-dAVF and the associated factors to achieve good clinical and angiographic outcomes. Methods: The data were analyzed from 165 consecutive patients diagnosed with CS-dAVF from January 2005 to September 2018. The demographic data included approaching route, embolization times, embolization material, sequence of embolization, number of embolization sessions, and angiographic and clinical outcomes. Interrater agreement of bilateral CS-dAVF diagnosis was performed using the κ coefficient. The factors associated with treatment outcome were analyzed using a Pearson χ2 test. Results: Bilateral CS-dAVF was detected in 43 patients (26%). Angiographic presentations that showed evidence of sinus thrombosis, dangerous venous drainage, and higher Satomi classification were more commonly found in bilateral CS-dAVF than in unilateral CS-dAVF. Good clinical outcome and cure from angiography were obtained in 90% and 74%, respectively. Ipsilateral inferior petrosal sinus–intercavernous sinus–contralateral cavernous sinus catheterization was the major approach route of treatment. The factors associated with improved clinical outcome were transvenous approach, shunt closure, coil embolization, and sequencing the embolization (P < 0.001). Conclusions: Dangerous venous drainage tends to increase in bilateral CS-dAVF. Retrograde ipsilateral inferior petrosal sinus catheterization using coil embolization and sequencing the embolization are the major concerns for treatment.en_US
