The understanding of the basic anatomy of the occipital artery (OA) is crucial, and computed tomography angiography is an effective tool for this purpose. In the present study, a comparison between healthy subjects and patients with internal carotid artery (ICA) stenosis and occlusion was made. The following parameters were measured: Age, sex, diameters and lengths of the OA in different locations, distance from the edge of the foramen magnum to the OA and the distance from the midline to the OA at the level of the superior nuchal line. A total of 205 participants who met the inclusion criteria were selected for further investigation. In addition, 50 healthy subjects (100 sides, left and/or right) were selected as the control group. A total of 155 patients (180 sides, left and/or right) were selected as the stenosis and occlusion groups, including the mild and moderate ICA stenosis group (50 sides, left and/or right), severe ICA stenosis group (80 sides, left and/or right) and the ICA occlusion group (50 sides, left and right). General information, measured parameters and statistical analysis results are provided for these groups. No significant differences were observed in the anatomical parameters of the OA among these groups. Thus, in addition to providing anatomical data, the present study demonstrates that stenosis and the occlusion of the ICA do not significantly alter the anatomy of the OA.
了解枕动脉（OA）的基本解剖结构至关重要，计算机断层血管造影是实现这一目的的有效工具。在本研究中，对健康受试者与颈内动脉（ICA）狭窄和闭塞患者进行了比较。测量了以下参数：年龄、性别、不同位置OA的直径和长度、枕骨大孔边缘至OA的距离以及在项上线水平从正中线至OA的距离。共选择了205名符合纳入标准的参与者进行进一步研究。此外，选择50名健康受试者（100侧，左侧和/或右侧）作为对照组。共选择155例患者（180侧，左侧和/或右侧）作为狭窄和闭塞组，包括轻度和中度ICA狭窄组（50侧，左侧和/或右侧）、重度ICA狭窄组（80侧，左侧和/或右侧）和ICA闭塞组（50侧，左侧和右侧）。提供了这些组的一般信息、测量参数和统计分析结果。这些组之间在OA的解剖参数上未观察到显著差异。因此，除了提供解剖学数据外，本研究还表明ICA的狭窄和闭塞不会显著改变OA的解剖结构。
