成人椎基底动脉延长扩张症CTA的诊断价值

Diagnostic Value of CTA in Adult Vertebrobasilar Dolichoectasia

目的:探讨多排螺旋CT联合CT血管造影(CTA)在成人椎基底动脉延长扩张症(VBD)中的诊断价值。方法:选取2016年1月至2021年6月收治、经临床明确诊断为VBD且资料完整的患者120例,按照年龄分为青年组(n=32)和中老年组(n=88),比较两组临床及影像学表现特征的统计学差异,并对CT平扫与CT平扫联合CTA两种成像手段的诊断符合率进行统计学比较。结果:中老年组责任临床表现的出现率(100%)明显高于青年组(15.63%)(P<0.05),中老年组阳性影像学征象指标的出现率及严重程度也明显高于青年组(P<0.05),联合成像的诊断符合率(100%)高于单纯CT平扫(90.83%)(P<0.05)。结论:成人VBD患者中老年患者更易出现临床症状,CT平扫联合CTA技术可提高成人VBD诊断的符合率。

Objective:To investigate the diagnostic value of multi-slice spiral CT combined with CT angiography(CTA)in adult vertebrobasilar dolichoectasia(VBD).Methods:A total of 120 patients who were admitted from January 2016 to June 2021 and were clinically diagnosed as VBD with complete data were selected.The patients were divided into the young group(n=)and the middle-aged group(n=)according to their ages,the statistics of the clinical and imaging characteristics and the diagnostic coincidence rates of CT plain scan and CT plain scan combined with CTA of the two groups were compared.Results:The occurrence rate of responsible clinical manifestations in the middle-aged and elderly group(100%)was significantly higher than that in the youth group(15.63%)(P<0.05),and the occurrence rate and severity of positive imaging signs in the middle-aged and elderly group were also significantly higher than those in the youth group(P<0.05).The diagnostic coincidence rate of combined imaging methods(100%)was higher than that in plain CT scan(90.83%)(P<0.05).Conclusion:The middle-aged and elderly patients with adult VBD are more likely to have clinical symptoms.CT plain scan combined with CTA can improve the coincidence rate of the diagnosis.
