Reversible symptomatic venous congestion after treatment of dural arteriovenous fistula using NBCA.

We treated a 73-year-old man with a dural arteriovenous fistula (AVF) with cortical venous drainage of the left mastoid region using transarterial embolization of the middle meningeal and occipital arteries with n-butyl 2-cyanoacrylate (NBCA). The patient's clinical symptoms improved dramatically. Three months after the procedure, follow-up CT showed resolution of white matter edema and follow-up angiograms showed no evidence of a recurrent AVF. This report indicates that dural AVFs without sinus drainage can be cured solely with transarterial NBCA embolization.
