Table 2.
Comparisons of the vertebral artery parameters between the 2 groups.
| VAs in patients (n=60) | VAs in controls (n=60) | P value | |
|---|---|---|---|
| LD (mm) | 3.25±0.51 | 3.51±0.41 | 0.003 |
| FV (ml/min) | 176±61.68 | 208±49.75 | 0.002 |
| PSV (cm/s) | 56.85±13.09 | 62.68±12.61 | 0.014 |
| EDV (cm/s) | 21.52±7.33 | 22.78±5.16 | 0.276 |
| RI | 0.62±0.09 | 0.63±0.08 | 0.536 |
Data expressed as mean ± standard deviation. VAs – vertebral arteries; LD – lumen diameter; FV – flow volume; PSV – peak systolic velocity; EDV – end-diastolic velocity; RI, (PSV-EDV)/PSV – resistive index.
