Abstract

INTRODUCTION - The pathomechanism of ischemic lesions in the vertebrobasilar territory is different from those of the carotid territory: the role of haemodynamical changes is very important. The frequency of developmental abnormalities is much more higher here than in the carotid territory. PATIENTS AND METHODS - The diameter and flow velocities of both vertebral arteries in 1100 adults on duplex scan were measured between the transverse process of the C5-6 vertebras. RESULTS - Normal anatomical structure and haemodynamic conditions were found in 980 cases. The mean diameter of the vertebral artery on the right side was 3.94±0.4 mm, on the left side 4.11±0.3 mm, measuring between the transverse processes of the C5-6 vertebras. Larger diameter was found in all age groups in men than in women. The blood flow velocity was higher on the left side. The mean systolic velocity on the right and left side was 44.6±7.7 and 45.4±7.6 cm/s, respectively, the mean diastolic velocity was 13.6±3.3 and 14.3±3.4 cm/s, respectively. Negative correlation was found between the age and velocity but the differences were not significant between the age groups. In 101 patients (9.2%) diameter was smaller than 3 mm, suggesting hypoplasia; flow disturbances occurred in 120 patients (11%): retrograde flow was present in 4 cases, increased flow in 11 cases, decreased flow was measured in the remaining cases. CONCLUSIONS -Our results provided normal parameters in a large population and called attention to the presence of frequent abnormalities of these vessels. Duplex ultra-sound was found to be useful in the examination of vertebral artery disturbances.
