[Possibilities and results of surgical treatment of vertebro-basilar insufficiency associated with atherosclerosis of the extracranial cerebral arteries].

The author describes his experience with the surgical treatment of processes leading to the syndrome of vertebrobasilar insufficiency. He differentiates between direct interventions focused primarily on the reconstruction of the pathologically altered vertebral artery. Interventions of the indirect type influence the vertebro-basilar insufficiency by modifying the deviated blood stream from the vertebrobasilar area. The author emphasizes reimplantation methods, as compared with desobliterations.
