摘要
目的:观察多层螺旋CT血管内成像(MSCTA)检查在颈动脉狭窄(CAS)诊断中的效能.方法:选取 2020 年 6 月至2022 年 5 月该院收治的 112 例疑似CAS患者进行横断面研究,所有患者均给予MSCTA检查、彩色多普勒超声(CDUS)检查,以数字减影血管造影(DSA)检查结果为"金标准",比较MSCTA检查与CDUS检查诊断CAS的效能,及对不同狭窄程度CAS的检出率.结果:经DSA检查结果显示,112 例疑似CAS患者中阳性 87 例,其中轻度狭窄 18 例、中度狭窄 17 例、重度狭窄 38 例、闭塞 14 例;阴性25例,其中脑梗死15例,颈动脉瘤10例.MSCTA检查结果显示,阳性87例,阴性25例;CDUS检查结果显示,阳性82例,阴性30例.MSCTA检查与CDUS检查诊断CAS的特异度、误诊率、阳性预测值比较,差异均无统计学意义(P>0.05);MSCTA检查诊断CAS的灵敏度、准确度、阴性预测值均高于CDUS检查,差异有统计学意义(P<0.05).MSCTA检查与CTA检查诊断轻中度狭窄CAS的检出率比较,差异无统计学意义(P>0.05);MSCTA检查诊断重度狭窄或闭塞CAS的检出率高于CDUS检查,差异有统计学意义(P<0.05).结论:CTA检查诊断CAS的效能高于CDUS检查.
Abstract
Objective:To observe efficiency of multi-spiral CT angiography(MSCTA)in diagnosis of carotid artery stenosis(CAS).Methods:A cross-sectional study was conducted on 112 patients with suspected CAS admitted to the hospital from June 2020 to May 2022.All patients were given MSCTA examination and color Doppler ultrasound(CDUS)examination.Using the results of digital subtraction angiography(DSA)as the'gold standard',the efficiency of MSCTA and CDUS in the diagnosis of CAS,and the detection rates of CAS with different degrees of stenosis were compared.Results:DSA showed that 87 of 112 patients with suspected CAS were positive,including 18 cases of mild stenosis,17 cases of moderate stenosis,38 cases of severe stenosis and 14 cases of occlusion.There were 25 cases were negative,including 15 cases of cerebral infarction and 10 cases of carotid aneurysm.MSCTA showed that 87 cases were positive and 25 cases were negative.CDUS examination showed that 82 cases were positive and 30 cases were negative.There were no significant differences in the specificity,the misdiagnosis rate and the positive predictive value between MSCTA and CDUS(P>0.05).The sensitivity,the accuracy and the negative predictive value of MSCTA in the diagnosis of CAS were higher than those of CDUS,and the differences were statistically significant(P<0.05).There was no statistically significant difference in the detection rate of mild to moderate stenosis CAS between MSCTA examination and CTA examination,the difference was not statistically significant(P>0.05).Further,the detection rate of CAS in the diagnosis of severe stenosis or occlusion by MSCTA was higher than that by CDUS,and the difference was statistically significant(P<0.05).Conclusions:The diagnostic efficiency of MSCTA in the diagnosis of CAS is higher than that of CDUS.
