Sažetak
The aim of this preliminary study is to estimate the relationship between radiologically visualized changes of the cervical spine and the haemodynamical changes in vertebral and basilar arteries measured by transcranial Doppler in patients suffering from vertiginous syndrome. The report reviewed 33 patients (16 male and 17 female), 12 of whom had no radiologically diagnosed changes of the servical spine, whereas 21 had such changes. Overall accuracy (ACC) and positive predictive value (PPV) of the radiological diagnosis were calculated to determinate the difference between the patients with normal and changed circulation. Overall accuracy of the radiological diagnosis for the right vertebral artery was 0.66, PPV was 0.71, and the physiological mean velocity range was 36+/-6 cm/sec. ACC for the left vertebral artery was 0.60, with PPV being 0.47 and the physiological mean velocity range 36+/-10cm/sec. Additionally, ACC for the basilar artery was 0.66, PPV was 0.52 and the mean velocity range was 42 + /-13cm/sec.
