Key Points

This study aims to identify factors influencing the venous penetration of N-butyl cyanoacrylate (NBCA) during transarterial embolization of dural arteriovenous fistulas (DAVFs).
Conducted a clinical study focusing on cases involving DAVFs.
Assessed venous penetration of NBCA-Lipiodol mixture during embolization procedures.
Collected data on various clinical factors and their association with penetration rates.
Identified specific clinical factors that significantly impact the venous penetration of NBCA.
Demonstrated a correlation between improved penetration and successful embolization outcomes.

Abstract

Objective: N-butyl cyanoacrylate (NBCA) must reach the venous side beyond the fistulous point (venous penetration) for the successful transarterial embolization of dural arteriovenous fistulas (DAVFs). The purpose of this study is to identify several factors associated with the venous penetration of NBCA.
