The surgical management of vertebrobasilar insufficiency

Vertebrobasilar insufficiency may result from structural lesions anywhere along the vertebrobasilar system. Recently developed techniques in angiography and microsurgery have made the vertebrobasilar system more accessible to surgical therapy. The syndrome of vertebrobasilar insufficiency is discussed, and our experience with the surgical treatment of lesions from the vertebral origin to the distal basilar region is reviewed.
