Abstract:
We used neurointerventional techniques to conduct a functional investigation of the artery responsible for hemifacial spasm in a 48-year-old woman. Insertion of a microcatheter into the posterior inferior cerebellar artery stopped the hemifacial spasm immediately and completely. The artery was verified intraoperatively as the vessel compressing the root exit zone of the facial nerve.
