摘　　要：目的 :研究颈椎横突孔骨折患者椎动脉损伤的发生率及椎动脉损伤的临床特征。方法 :选择2 0 0 0年 8月 - 2 0 0 3年 6月 ,CT证实的 2 5例急性颈椎横突孔骨折患者进行颈部动脉磁共振血管造影(MRA)检查。结果 :12例患者发生椎动脉损伤 (48% ) ,其中 8例为单侧损伤 ,4例为双侧损伤 ;椎动脉损伤的发生率在横突孔骨折伴小关节绞锁脱位组与横突孔骨折无小关节绞锁脱位组之间有统计学差异(P =0 0 3)。 2例椎动脉损伤患者出现椎基底动脉缺血症状。结论 :急性颈椎横突孔骨折患者椎动脉损伤的发生率较高 ,尤其伴小关节绞锁脱位者 ;大多数椎动脉损伤患者无特异性临床表现。Objective:To study the incidence and clinical features of vertebral artery injury after cervical transverse foramen fracture.Methods:From August 2000 to June 2003,25 patients with fracture of the cervical transverse foramen were studied by means of magnetic resonance angiography(MRA).Results:Vertebral artery injuries were found in 12 patients(48%).Four patients had bilateral vertebral artery injuries,and 8 patients had unilateral vertebral artery injuries.The incidence of vertebral artery injury after cervical transverse foramen fracture had statistical significance between locked and unlocked facet dislocation groups.Two patients had symptoms of vertebrobasilar ischemia.Conclusion:The incidence of vertebral artery injury after cervical transverse foramen fracture is quite high,particularly those associated with locked facet dislocation.Most cases of vertebral artery injury have no symptoms of vertebrobasilar ischemia.
