Embolization was feasible in all cases. In one case, a small craniotomy was specifically performed to allow needle positioning. In all cases n-butyl cyanoacrylate was used. No ischemic or hemorrhagic complications related to embolization occurred. Complete or near complete devascularization was obtained in all cases. In one case, surgery was not performed and the patient was monitored.
