Morphologic and hemodynamic characteristics of vertebral arteries in men and women

Introduction: Men and women differ in diameters and MBFVs in VAs. Aim: to compare morphology and hemodynamics of VAs between sexes.Patients and methods: We examined 155 subjects using a linear 7.5 MHz probe (Aloka Prosound SSD-5500). Measurements were obtained at the V2 segment of VAs. Criteria: VA diameter of 2-4mm, systolic MBFVs of 0.35-0.70m/s, normal resistance pattern. Investigated parameters: diameters of VAs, MBFVs in VAs, sum of VA diameters, sum of MBFVs in VAs, diameter of the narrower and wider VA, and age.Results: 68 men and 87 women ; 88 with a dominant left VA (56% of men and 58% of woman), 11 (7%) showed no dominance. Group differences: men had both VAs wider, and a larger diameter of the “ wider” VA. There were no differences in MBFVs between men and women.Conclusion: Left VA is dominant in both sexes. There was no difference in MBFVs among sexes. Men have a wider VA than women.
