目的综合分析脑血管疾病(CVD)多层CT血管造影(CTA)与数字减影血管造影术(DSA)影像诊断的临床诊断价值。方法 38例CVD患者作为研究对象,随机分为A、B两组,每组19例。A组应用多层CTA诊断,B组应用DSA诊断。结果 A组CVD患者检查结果 :2例基底动脉瘤,3例大脑前动脉瘤,6例大脑中动脉瘤,6例前交通动脉瘤,3例后交通动脉瘤,其中有1例误诊。B组CVD患者检查结果 :2例基底动脉瘤,3例大脑前动脉瘤,5例大脑中动脉瘤,6例前交通动脉瘤,3例后交通动脉瘤;无一例误诊。A组对脑动脉瘤的特异性以及敏感性分别为96.99%、94.22%,B组对脑动脉瘤的特异性以及敏感性分别为98.26%、95.21%,两组敏感性以及特异性比较差异无统计学意义(P>0.05)。结论 CVD患者应用CTA与DSA影像诊断的临床诊断价值均较高。
Objective To analyze the clinical value of multi-slice CT angiography (CTA) and digital subtraction angiography (DSA) in the diagnosis of cerebrovascular disease (CVD). Methods Thirty-eight patients with CVD were randomly divided into A and B groups, 19 cases in each group. A group using multi-slice CTA diagnosis, B group using DSA diagnosis. Results The results of CVD patients in group A were as follows: 2 cases of basilar artery aneurysm, 3 cases of anterior cerebral artery aneurysm, 6 cases of middle cerebral artery aneurysm, 6 cases of anterior communicating artery aneurysm and 3 cases of posterior communicating artery aneurysm, of which 1 case was misdiagnosed. The results of CVD patients in group B were as follows: 2 cases of basilar artery aneurysm, 3 cases of anterior cerebral artery aneurysm, 5 cases of middle cerebral artery aneurysm, 6 cases of anterior communicating artery aneurysm and 3 cases of posterior communicating artery aneurysm. No case was misdiagnosed. The specificity and sensitivity of group A to cerebral aneurysm were 96.99% and 94.22% respectively. The specificity and sensitivity of group A to cerebral aneurysm were 98.26% and 95.21% respectively. There was no significant difference between the two groups in the sensitivity and specificity Statistical significance (P> 0.05). Conclusion The diagnostic value of CTA and DSA in CVD patients is high.
