[Clinical and expert opinion aspects of vertebrobasilar insufficiency].

As many as 103 patients with vertebral basilar failure (VBF) underwent clinical expert examination. The patients' age ranged from 34 to 58 years. Bearing in mind the clinicopathogenetic characteristics, the patients were distributed into 3 groups. Group I (n = 32) included patients with the irritable vertebral artery syndrome, group II (n = 54) was made up of patients with mixed spondylogenous atherosclerotic chronic VBF, and group III (n = 17) of patients with sequelae of strokes in the vertebral basilar basin. Indications for patients' referral to the medical expert commission for evaluation of working capacity were elaborated and the clinical and socio-occupational criteria for the loss of patients' work fitness were established. A table describing stages of the development of VBF of spondylogenous atherosclerotic genesis was devised.
