Abstract：
METHODS: A prospective study.
OBJECTIVE: To investigate the incidence of vertebral artery (VA) occlusion and whether anterior spinal artery (ASA) is occluded in cervical facet dislocation.
METHODS: University hospital, China.
METHODS: During a 2-year period, 21 conventional patients with cervical facet dislocation were prospectively enrolled. All patients received computed tomography angiography (CTA) to assess the patency of the VA, anterior radiculomedullary arteries (ARAs), and ASA at the time of injury. Clinical data were documented, including demographics, symptomatic vertebrobasilar ischemia, American Spinal Injury Association Impairment Scale (ASIA) grades, and ASA and VA radiological characteristics.
RESULTS: VA unilateral occlusion occurred in 5 of 21 patients (24%), including 2 with unilateral facet dislocation and 3 with bilateral facet dislocation. No ASA occlusion was found in all 21 patients, including 5 with VA unilateral occlusion. No patients had symptomatic vertebrobasilar ischemia.
CONCLUSIONS: VA occlusion occurs in approximately one-fourth of cervical facet dislocations, with infrequent symptomatic vertebrobasilar ischemia. ASA is not occluded following cervical facet dislocation, even with unilateral VA occlusion.

摘要：
方法：前瞻性研究。
目的：探讨颈椎小关节脱位时椎动脉（VA）闭塞的发生率及脊髓前动脉（ASA）是否闭塞。
方法：大学医院，中国。
方法：在2年内，前瞻性纳入21例颈椎小关节脱位的常规患者。所有患者均接受计算机断层扫描血管造影（CTA）以评估VA的通畅性，神经根前动脉（ARAs），和受伤时的ASA。记录了临床数据，包括人口统计，症状性椎基底动脉缺血，美国脊髓损伤协会减损量表（ASIA）等级，ASA和VA放射学特征。
结果：21例患者中有5例（24％）发生了VA单侧闭塞，其中单侧小关节脱位2例，双侧小关节脱位3例。在所有21例患者中均未发现ASA闭塞，其中5例伴有VA单侧闭塞。没有患者出现症状性椎基底动脉缺血。
结论：VA闭塞发生在大约四分之一的颈椎关节突脱位中，很少有症状的椎基底动脉缺血。颈椎小关节脱位后ASA未闭塞，即使是单侧VA闭塞。
