【摘要】 目的 分析颈性眩晕的影像学特点，并评价彩色超声多普勒(CDUS)联合CT血管成像(CTA)、增强磁共振血管成像(CEMRA)在颈性眩晕中的应用价值。方法 62例临床诊断为颈性眩晕患者作为病例组，其中39例行颈部血管超声和颈部CTA检查，23例行颈部血管超声和颈部CEMRA。选取30例正常志愿者作为对照组，其中18例行颈部血管超声和颈部CTA检查，12例行颈部血管超声和颈部CEMRA。评价2组间椎动脉血流动力学及形态学的情况。比较CDUS与CTA/CEMRA对椎动脉形态学检测的差异。结果 (1)在形态学方面：颈性眩晕组中椎动脉狭窄率(46.77%)及变异率(29.03%)均高于对照组椎动脉狭窄率(23.33%)及变异率(6.67%),差异有统计学意义(均P<0.05)。颈性眩晕组椎动脉迂曲发生率(11.29%)与对照组(13.33%)比较，差异无统计学意义(P>0.05)。(2)在血流动力学方面：CDUS显示颈性眩晕组血流下降发生率(66.13%)高于对照组(10.00%),差异有统计学意义(P<0.05)。颈性眩晕组椎动脉狭窄(86.21%)及变异者(72.22%)血流速度下降发生率明显高于椎动脉迂曲(28.57%)及椎动脉正常者(12.50%)。结论 应用CDUS联合CTA/CEMRA,可从责任血管形态学、血流动力学方面综合评价颈性眩晕的病因，对颈性眩晕的诊治具有重要意义。更多还原

【Abstract】 Objective To analyze the imaging characteristics and to evaluate the application value of color doppler ultrasonography(CDUS) combined with CT angiography(CTA) and contrast-enhanced magnetic resonance angiography(CE-MRA) in patients with cervical vertigo.Methods 62 patients diagnosed with cervical vertigo clinically were enrolled.Neck CDUS and neck CTA were performed on 39 patients.Neck CDUS and neck CE-MRA were performed on 23 patients.Neck CDUS and CTA/MRA were performed on 30 normal volunteers,which were chosen as control group.Neck CDUS and neck CTA were performed on 18 normal volunteers.Neck CDUS and neck CE-MRA were performed on 12 normal volunteers.Hemodynamics and morphology were evaluated and compared between the two groups.Results In aspect of morphology:The incidence of vertebral artery(VA) stenosis(46.77%) and VA variation(29.03%) in cervical vertigo group were higher than VA stenosis(23.33 %) and VA variation(6.67%) in control group with significant difference(all P<0.05).The incidence of tortuous VA showed no statistics difference between cervical vertigo group(11.29%) and control group(13.33%)(P>0.05).In aspect of hemodynamics:The decline incidence of peak systolic velocity detected by CDUS in cervical vertigo group(66.13 %) was higher than that in control group(10.00%) with statistically significant difference(P<0.05).The peak systolic velocity decline incidence of VA stenosis(86.21 %) and VA variation(72.22%) were higher than that of VA tortuous(28.57%) and VA normal(12.50%) patients in cervical vertigo group.Conclusion The application of CDUS combined with CTA or CE-MRA could provide valuable diagnostic and therapeutic information for cervical vertigo in the aspects of change in vascular morphology and cerebral hemodynamics,which could further provide objective basis for clinical diagnosis and treatment.更多还原
