目的探讨64层螺旋CT对寰椎椎动脉沟环综合征的诊断价值.方法收集因常规颈椎正侧位X线检查发现的寰椎椎动脉沟环患者48例,进行64层螺旋CT容积扫描后,进行容积重建和多平面重建,多方位显示寰椎结构形态及寰枢关节间隙,并探讨其与临床症状之间的关系.结果 48例寰椎椎动脉沟环患者中,右侧完整环型24例,孔径(6.59±0.50)mm,左侧完整环型36例,孔径(6.19±0.49)mm,右侧不完整环型24例,左侧不完整环型12例.30例诊断为寰椎椎动脉沟环综合征,均有寰枢关节不稳及不同程度头颈转动性眩晕症状.结论 64层螺旋CT能清晰显示寰椎后弓桥的解剖结构和测量寰椎椎动脉沟环的孔径,结合对枕颈失稳的判断,对寰椎椎动脉沟环综合征具有重要的诊断价值.

Objective To explore the diagnostic value of 64-slice spiral CT on atlas vertebral artery sulcus ring syndrome.Methods The 48 atlas vertebral artery sulcus ring patients who were found by conventional anterior posterior and lateral X-ray film were collected.The 64-slice spiral CT volume scan and following volume restitution(V R)and multiplanar reconstruction(MPR)were underwent,and multi-directional structural morphology was displayed.Their relationship with clinical features were analyzed.Results Among 48 cases of atlas vertebral artery sulcus ring,24 cases were shown with right complete bridge[pore size(6.59±0.50)mm],36 cases with left complete bridge[pore size(6.19±0.49)mm],24 cases with right incomplete bridge and 12 cases with left incomplete bridge.Thirty cases were diagnosed as atlas vertebral artery sulcus ring syndrome,and all had the atlantoaxial joint asymmetry and vertigo of different degree when head and neck rotated.Conclusions The 64-slice spiral CT can clearly display the anatomical features of posterior bridge of atlas and measure the pore size of atlas vertebral artery sulcus ring,and it has important diagnostic value for atlas vertebral artery sulcus ring syndrome.
