RESULTS OF THE SURGICAL-TREATMENT OF THE VERTEBROBASILAR INSUFFICIENCY, CAUSED BY ANOMALOUS RETROGRADE ORIGIN OF THE A-VERTEBRALIS

From February 1987 till March 1989 131 patients were operated for vert ebrobasilar insufficiency caused by anomalous retrograde origin of the A. vertebralis. 131 operations were performed: 59 reinplantations of the A. vertebralis in the A. subclavia, 79 rotations and fixations of the A. subclavia to the first rib. No deaths or strokes occured during the early postoperative period, A recurrence of neurologic symptoms w as observed in 54 patients (52.9 +/- 2.4%) during the mean follow-up p eriod of 59.4 +/- 1.4 months. We conclude that anomalous retrograde or gin of the A. vertebralis from the A. subclavia is an indication for o peration, if the role of this pathology for genesis of vertebrobasilar insufficiency has been proven. The monophotone emission tomography of the brain is an important method of diagnosis. The operation of choic e is the reimplantation of the A. vertebralis in the A. subclavia.
