The Treatment Outcome of Transarterial Embolization for Isolated Sinus Type Dural Arteriovenous Fistula between NBCA and Onyx

Abstract

Objective: The purpose of this study was to compare the clinical outcome of transarterial embolization for isolated sinus type dural arteriovenous fistula (iDAVF) using n-butyl-cyanoacrylate (NBCA) and Onyx.Methods: Seventeen lesions of iDAVF in 17 patients who underwent transarterial embolization between March 2008 and February 2015 were retrospectively analyzed. They were treated by embolization using NBCA in 10 patients, Onyx in 5 patients, and combination of NBCA and Onyx in 2 patients. We compared the results between embolization with NBCA and Onyx as follows: complete occlusion rate, number of embolized vessels, procedure-related complications, treatment time, dose of radiation exposure, amount of contrast agent, and total cost of the devices. Results:The complete occlusion rate of iDAVF was significantly higher in the Onyx group: 4 of 10 (40%) No significant difference was observed in the treatment time and contrast agent dose. Conclusion:In transarterial embolization of iDAVF, a higher complete occlusion rate was obtained with Onyx, which was also advantageous for reducing the exposure dose and cost of the devices.

In the present patient, the feeder was occluded with coils alone, but concomitant use of a liquid embolic agent with coils may be medical economically advantageous, as reported by Shi et al 7) .…”
