摘　　要：目的分析在脑动脉瘤的诊断中采用多排螺旋CT血管成像(CTA)与数字减影血管造影(DSA)在临床上的实际应用价值。方法本研究通过临床筛选2019年4月至2023年4月在我院收治的疑似脑动脉瘤患者50例,均行CTA及DSA检查,手术确诊40例,其余10例未检出。对比2组患者脑动脉瘤的分布情况、动脉瘤测量情况,2种诊断方式的诊断效能与诊断时间。结果颅内微小动脉瘤、小动脉瘤采用CTA诊断的检出率为20.0%、17.5%,采用DSA诊断的检出率为2.5%、0,CTA检出率较高;CTA诊断敏感性、特异性、准确率分别为94.2%、87.5%、93.3%,均高于DSA诊断的73.1%、62.5%、70.0%(P<0.05);2种诊断方式对中等动脉瘤、大动脉瘤、巨大动脉瘤的检出率差异无统计学意义;动脉瘤瘤颈平均大小、瘤体长径、瘤体短径在研究组的结果中表现为(3.2±0.5)mm、(10.6±1.3)mm、(5.5±0.6)mm,与对照组的(3.7±0.4)mm、(11.0±1.6)mm、(5.4±0.4)mm比较无统计学意义(P>0.05)。结论CTA在临床诊断中具有较高的灵敏度和特异度和准确度,可在临床推广应用。Objective To analyze the clinical value of multi-slice spiral CT angiography(CTA)and digital subtraction angiography(DSA)in the diagnosis of cerebral aneurysms.Methods In this study,50 patients with suspected cerebral aneurysm admitted to our hospital from April 2019 to April 2023 were clinically screened,And they were detected by DSA and CTA.The distribution of cerebral aneurysms,the measurement of aneurysms,the diagnostic efficiency and diagnostic time of the two diagnostic methods were compared between the two groups.Results The detection rates of CTA and DSA were 20.0%and 17.5%,respectively.The detection rates of DSA were 2.5%and 0,respectively.The diagnostic sensitivity,specificity and accuracy of CTA were 94.2%,87.5%and 93.3%,respectively,which were higher than those of DSA(73.1%,62.5%and 70.0%)(P<0.05).There were no differences in the detection rate of medium aneurysm,large aneurysm and giant aneurysm between the two diagnostic methods.The average aneurysm neck size,tumor length diameter and tumor short diameter were(3.2±0.5)mm,(10.6±1.3)mm,(5.5±0.6)mm in the study group,and(3.7±0.4)mm,(11.0±1.6)and(5.4±0.4)mm in the control group.There were no statistical significances between 2 groups(P>0.05).Conclusion CTA has higher application value in clinical diagnosis,not only has higher detection rate and accuracy,but also has higher sensitivity and specificity,which can be popularized in clinical application.
