Anatomic dissection and measurements of the vertebral artery relative to the medial margin of the longus colli and the anterior margin of the vertebral body from C6 to C3 were performed in this study. The average angle of the vertebral artery relative to the midline was 4.3 +/- 2.6 degrees overall. The average distance between the medial margin of the longus colli and medial margin of the vertebral artery gradually decreased from the C6 level (11.5 +/- 1.0 mm) to the C3 level (9.0 +/- 1.3 mm). The average distance between anterior margin of the vertebral body and anterior margin of the vertebral artery gradually increased from the C6 level (7.2 +/- 1.9 mm) to the C3 level (9.6 +/- 2.1 mm). The distance between medial borders of the longus colli muscles gradually decreased from the C6 level (13.8 +/- 2.2 mm) to the C3 level (7.9 +/- 2.2 mm). Relative to the medial margin of the longus colli muscle and the anterior margin of the vertebral body, the vertebral artery is more lateral and anterior at the C6 level but more medial and posterior at C3 level. This knowledge may facilitate effective decompression of the lateral cervical canal and improve the margin of safety of the surgeon.
本研究对椎动脉相对于颈长肌内侧缘和椎体前缘从C6至C3进行了解剖及测量。椎动脉相对于中线的平均角度总体为4.3±2.6度。颈长肌内侧缘与椎动脉内侧缘之间的平均距离从C6水平（11.5±1.0毫米）至C3水平（9.0±1.3毫米）逐渐减小。椎体前缘与椎动脉前缘之间的平均距离从C6水平（7.2±1.9毫米）至C3水平（9.6±2.1毫米）逐渐增加。颈长肌内侧缘之间的距离从C6水平（13.8±2.2毫米）至C3水平（7.9±2.2毫米）逐渐减小。相对于颈长肌内侧缘和椎体前缘，椎动脉在C6水平更偏外侧和前方，但在C3水平更偏内侧和后方。这一知识可能有助于有效减压颈椎外侧管并提高外科医生的安全边际。
