Sažetak
The study reviewed patients suffering from vertebrobasilar disorders - 38 patients experienced them after changing the head position, followed by 57 patients who had them resting - and the group of 59 healthy examinees. The transcranial Doppler (TCD) was used to measure the mean velocity (cm/s) of intracranial parts of vertebral and basilar arteries. The measuring was per-formed having the head in its physiological position, followed by the provoking test positions. The radiological neck spine findings were analyzed, and the electronistagmography and heat experiment were performed. The study results showed the significant changes of mean velocity in verte-bral arteries and basilar arteries intracranial parts, in patients comparing them to healthy group. The circulation velocity changes were more significant in the patients suffering from the vertebrobasilar disorders evident after assuming the head provoking positions than in the group of patients who had them resting. The result analysis obtained in the group of the patients with vertebrobasilar disorders, who were in the provoking position, suggest that the circulation disor-ders are related to the head positions and can be detected applying the Doppler circulation velocity measuring in the vertebral arteries, whereas the radiological finding of the neck spine showed far less visible changes in comparison to the healthy group. In the group of the vertebrobasilar patients, who were resting, the result analysis did not show any correlation between the disorders and circulation changes, that can be detected by Doppler circulation velocity mea-suring nor was the radiological neck spine finding of any importance, when we differentiated the sick ones from the healthy ones. The electronistagmographic finding and heat experiment did not help to detect and divide the patients with the vertebrobasilar disorders.
