  • Title: Iatrogenic arteriovenous fistula of the middle meningeal artery caused during embolization for meningioma--case report.
    Author: Terada T, Nakai E, Tsumoto T, Itakura T.
    Journal: Neurol Med Chir (Tokyo); 1997 Sep; 37(9):677-80. PubMed ID: 9330531.
    Abstract:
    A 73-year-old female developed middle meningeal arteriovenous fistula during embolization of a falx meningioma. The cause of this complication was thought to be perforation by the guide wire during catheterization at the sharp bend in the sphenoidal portion of the middle meningeal artery. Embolization of the fistula and the feeding artery to the meningioma with polyvinyl alcohol particles 250-355 microns size resulted in complete obliteration of the fistula. Computed tomography showed no epidural or subdural hematoma. Introduction of the microcatheter beyond the sharp bend in the middle meningeal artery should not be attempted to avoid the possibility of iatrogenic middle meningeal arteriovenous fistula.
