Abstract

BACKGROUND AND PURPOSE

The vertebral artery (VA) is important for the development of the transverse foramen (TF). Most studies of these structures have focused on anatomical anomalies. Therefore, we investigated quantitatively the association between the relative sizes of the TF and VA.

METHODS

We recruited a consecutive series of subjects who underwent CT angiography to estimate the relative sizes of the VA and TF in axial source images. Two neurologists independently reviewed the axial CT images of 208 patients who had no history of transient ischemic attack or stroke. Averaged areas of the VA and TF were defined by the sum of the areas at each level from C3 to C6, divided by 4. Correlation analyses were adjusted for age, sex, and vascular risk factors.

RESULTS

The mean age of the subjects was 53 years. The interobserver and intraobserver reliabilities of TF size were good. There was a linear relationship between the sizes of the VA and TF on each side (right side: r(2)=0.58, p<0.001; left side: r(2)=0.62, p<0.001). The area of the VA was significantly associated with that of the TF after adjusting for vascular risk factors.

CONCLUSIONS

The size of the VA is strongly and linearly correlated with the size of the TF. These findings suggest that measurement of the TF and VA with CT angiography is a reliable method for evaluating VA diseases, and may provide new insight into the differentiation between VA hypoplasia and atherosclerosis of the VA.

摘要

背景与目的

椎动脉（VA）对于横突孔（TF）的发育很重要。大多数关于这些结构的研究都集中在解剖学异常上。因此，我们定量研究了 TF 和 VA 相对大小之间的关系。

方法

我们招募了一系列连续接受 CT 血管造影的受试者，以在轴位源图像上估计 VA 和 TF 的相对大小。两名神经科医生独立审查了 208 名无短暂性脑缺血发作或中风病史的患者的轴向 CT 图像。VA 和 TF 的平均面积通过 C3 至 C6 每个水平的面积之和除以 4 来定义。相关性分析调整了年龄、性别和血管危险因素。

结果

受试者的平均年龄为 53 岁。TF 大小的观察者间和观察者内可靠性良好。每侧 VA 和 TF 的大小之间存在线性关系（右侧：r²=0.58，p<0.001；左侧：r²=0.62，p<0.001）。在校正血管危险因素后，VA 的面积与 TF 的面积显著相关。

结论

VA 的大小与 TF 的大小呈强线性相关。这些发现表明，使用 CT 血管造影测量 TF 和 VA 是评估 VA 疾病的可靠方法，并可能为 VA 发育不良和 VA 粥样硬化的鉴别提供新的见解。
