摘要
目的探讨容积CT数字减影血管成像在后循环脑梗死椎动脉狭窄中的应用。方法选取2015年5月至2017年5月我院收治的后循环脑梗死患者40例,所有患者均接受CT血管造影(CTA)检查和数字减影血管造影(DSA)检查,对CTA和DSA检查结果进行统计分析。结果 40例患者中,CTA检查椎动脉异常38例,异常率为95%,发育不良型狭窄8例,椎动脉狭窄30例(60支),其中狭窄42支,狭窄率为70%,起始部狭窄26支,双侧狭窄16例,双侧狭窄率为40%;DSA检查椎动脉异常38例,异常率为95%,发育不良型狭窄8例,椎动脉狭窄30例(60支),其中狭窄46支,狭窄率为77%,起始部狭窄28支,双侧狭窄16例,双侧狭窄率为40%。CTA检查和DSA检查椎动脉异常率、狭窄率、双侧狭窄率之间的差异均无统计学意义(P>0.05)。以DSA检查结果为金标准,CTA检查诊断椎动脉狭窄的敏感度为89%(48/54),特异度为92%(24/26),准确性为90%(72/80),阳性预测值为96%(48/50),阴性预测值为80%(24/30)。结论容积CT数字减影血管成像在后循环脑梗死椎动脉狭窄中的应用价值高。
Objective To investigate the application of volume CT digital subtraction angiography in the vertebral artery stenosis of posterior circulation cerebral infarction.Methods A total of 40 cases of patients with posterior circulation cerebral infarction admitted to our hospital from May 2015 to May 2017 were randomly selected.All patients received CTA examination and DSA examination,and the results of CTA examination and DSA examination were statistically analyzed.Results Among the 40 cases of patients,CTA examination of vertebral artery abnormalities 38 cases,the abnormal rate was 95%,dysplasia stenosis 8 cases,vertebral artery stenosis 30 cases(60),of which stenosis 42 branches,the stenosis rate was 70%,initial part of stenosis 26 branches,bilateral stenosis 16 cases,the bilateral stenosis rate was 40%;DSA examination of abnormal vertebral artery 38 cases,the abnormal rate was 95%,dysplasia stenosis 8 cases,vertebral artery stenosis 30 cases(60 branches),of which stenosis 46 branches,the stenosis rate was 78%,initial part of stenosis 28 branches,bilateral stenosis 16 cases,the bilateral stenosis rate was 40%.The differences of abnormal rates,stenosis rates and bilateral stenosis rates of vertebral artery between CTA examination and DSA examination were not significant(P>0.05).DSA examination were taken as gold standard,the sensitivity of CTA in the diagnosis of vertebral artery stenosis was 89%(48/54),the specificity was 92%(24/26),the accuracy was 90%(72/80),the positive predictive value was 96%(48/50),and the negative predictive value was 80%(24/30).Conclusion The volume CT digital subtraction angiography is of high application value in the vertebral artery stenosis of posterior circulation cerebral infarction.
