Objectives

This study investigated whether there was a relationship between steno-occlusion of the vertebral artery (VA) segments and the dominant VA side.

Materials and methods

Angiography results of 215 patients (146 men; 69 women) were retrospectively analyzed in this study. The patients were divided into three groups: dominant, non-dominant and co-dominant. These groups were compared according to the presence of steno-occlusion in the vertebral artery segments. The results were evaluatedusing X², Mann-Whitney U and Kruskal-Wallis tests. For correlation analysis, Spearman's Rho test was used.

Results

The findings showed that 55 of 215 patients (25.6%) had a right dominant VA, and 103 (47.9%) had left dominant VA. There was no significant relationship between dominance and age or gender (p > 0.05). More vertebral artery stenosis (VAS) was found on the dominant side. However, a significant relationship only in the right dominant V1 segment (p = 0.044) was noticed. Hypoplastic VA was detected in 13 patients (6%). Most of the VAs (98.4%, n = 423) arose from the subclavian artery.

Conclusions

In conclusion, we found more vertebral artery stenosis on the dominant side than the co-dominant side, especially on the origin of the vertebral arteries. However, it was only significant on the right dominant V1 segment, regardless of age and gender of the patients (p > 0.05).

椎动脉优势与椎动脉节段狭窄闭塞之间的关联：一项回顾性血管造影研究

目标

这项研究调查了椎动脉 (VA) 段的狭窄闭塞与主要 VA 侧之间是否存在关系。

材料和方法

本研究回顾性分析了 215 名患者（146 名男性；69 名女性）的血管造影结果。将患者分为三组：显性、非显性和共同显性。这些组根据椎动脉节段中狭窄闭塞的存在进行比较。使用X ²、Mann-Whitney U 和Kruskal-Wallis 检验评估结果。对于相关性分析，使用了 Spearman 的 Rho 检验。

结果

结果显示，215 名患者中有 55 名 (25.6%) 为右侧优势 VA，103 名 (47.9%) 为左侧优势 VA。优势与年龄或性别之间没有显着关系（p > 0.05）。在优势侧发现更多的椎动脉狭窄（VAS）。然而，仅在正确的主导 V1 段 (p = 0.044) 中才注意到显着关系。在 13 名患者 (6%) 中检测到发育不全的 VA。大多数 VA（98.4%，n = 423）来自锁骨下动脉。

结论

总之，我们发现优势侧的椎动脉狭窄多于共同优势侧，尤其是在椎动脉的起源处。然而，无论患者的年龄和性别如何，它仅在右侧显性 V1 节段上显着（p > 0.05）。
