背景：目前对颅内椎动脉发育不全（VAH）血管壁特征的研究很少。本研究的目的是通过三维容积各向同性快速自旋回波采集（3D VISTA）图像确定VAH的壁特征，并区分获得性动脉粥样硬化狭窄和VAH。方法：回顾性分析2014年1月至2015年2月30例经影像学检查可疑VAH患者的临床资料。基于3D VISTA图像，患者被分类为“获得性动脉粥样硬化性狭窄”或“VAH”。根据室壁特征判断是否存在动脉粥样硬化病变，并将患者分为两个亚组（伴动脉粥样硬化的VAH和正常室壁的VAH）。基底动脉和椎动脉的血管壁特征也进行了评估。比较两组患者的临床表现及室壁特征。结果：30例可疑VAH患者中，5例经3D VISTA图像确诊为获得性动脉粥样硬化狭窄。25例患者最终诊断为VAH，其中动脉粥样硬化16例（64.00%），室壁正常9例（36.00%）。16例动脉粥样硬化患者中，9例有斑块，6例有轻度管壁增厚，1例有血栓及管壁增厚。与室壁正常的VAH患者相比，合并动脉粥样硬化的VAH患者基底动脉和优势椎动脉粥样硬化的发生率更高（P = 0.000）。结论：三维VISTA图像能够区分获得性动脉粥样硬化性狭窄和VAH。VAH也容易发生动脉粥样硬化过程。
Background:There are few studies for evaluating wall characteristics of intracranial vertebral artery hypoplasia (VAH). The aim of this study was to determine wall characteristics of VAH with three-dimensional volumetric isotropic turbo spin echo acquisition (3D VISTA) images and differentiate between acquired atherosclerotic stenosis and VAH. Methods:Thirty patients with suspicious VAH by luminograms were retrospectively enrolled between January 2014 and February 2015. The patients were classified as “acquired atherosclerotic stenosis” or “VAH” based on 3D VISTA images. The wall characteristics of VAH were assessed to determine the presence of atherosclerotic lesions, and the patients were classified into two subgroups (VAH with atherosclerosis and VAH with normal wall). Wall characteristics of basilar arteries and vertebral arteries were also assessed. The clinical and wall characteristics were compared between the two groups. Results:Five of 30 patients with suspicious VAH were finally diagnosed as acquired atherosclerotic stenosis by 3D VISTA images. 25 patients were finally diagnosed as VAH including 16 (64.00%) patients with atherosclerosis and 9 (36.00%) patients with normal wall. In the 16 patients with atherosclerosis, plaque was found in 9 patients, slight wall thickening in 6 patients, and thrombus and wall thickening in 1 patient. Compared with VAH patients with normal wall, VAH patients with atherosclerosis showed atherosclerotic basilar arteries and dominant vertebral arteries more frequently (P = 0.000). Conclusions:Three-dimensional VISTA images enable differentiation between the acquired atherosclerotic stenosis and VAH. VAH was also prone to atherosclerotic processes.
