[Circulatory disorders in the vertebrobasilar drainage area]

The authors refer to the clinical symptoms and auxiliary investigation results in 50 out-patients monitored for vascular cerebral disease in attempt to make a reliable diagnosis of vertebrobasilar insufficiency. The computerized brain tomography (CT) and ultrasound vascular investigation though being highly reliable in routinely diagnosing ischaemia of carotid drainage, are of lesser informative value in respect with structures of posterior cranial fossa. The considerable risk of cerebral infarction onset in patients with vertebrobasilar insufficiency in history is mandatory for more efforts as to the etiopathogenetic management of such casualties.
