Оценка взаимосвязи характера хода позвоночных артерий и вен с морфометрическими и гемодинамическими показателями по результатам ультразвуковых исследований
INTRODUCTION: Vertebral arteries and veins are the most vulnerable part of cerebral hemodynamics and are well accessible for visualization at ultrasound examination. AIM: To determine the relationship between the course and individual anatomical features of the vertebral arteries and veins when performing ultrasound examinations. MATERIALS AND METHODS: Two hundred thirty-three volunteers, aged from 18 to 86 years were examined using diagnostic equipment SonoAce R7, Logiq F6. The data were grouped based on the course of the vessels and the gender of patients; statistical analysis was performed. RESULTS: A straight course of vessels both sides was found in 52 individuals, not straight in 90, and the course did not coincide in 91 cases. The highest systolic blood linear velocity with the straight course of the arteries was on the left. The volume velocity was 84.0 ± 34.9 ml/min in the straight course, 84.9 ± 34.4 ml/min in the non-straight course. CONCLUSION: The smallest difference in diameter of arteries was observed with a bilateral non-straight course. The highest blood volume velocity was recorded in arteries on the left with the straight course. The lowest hemodynamic parameters were noted in vertebral veins with the bilateral non-straight course. The average diameter of veins regardless of the side of visualization did not depend on the course and was 1.4 ± 0.3 mm. In the non-straight course, the volume velocity of venous blood flow was 11.3–12.3 ml/min, in the straight course 17.2 ± 11.7 ml/min.
