摘　　要：目的分析经头颈部CT血管造影(CTA)联合三维重建技术对脑血管疾病的特点及对脑血管疾病动脉狭窄的诊断作用。方法选择我院在2021年8月至2022年8月期间收治的脑血管疾病动脉狭窄患者118例进行观察,所有患者均进行经头颈部CTA检查,将获取的图像,完成最大密度投影和血管三维重建,将数字减影血管造影(DSA)检查结果作为“金标准”,分析经头颈部CTA联合三维重建的诊断特点,对脑血管疾病动脉狭窄患者的诊断价值。结果以DSA检查结果作为“金标准”,经头颈部CTA联合三维重建技术对脑血管动脉狭窄患者的灵敏度、特异度、准确率、阳性及阴性预测值更高,118例脑血管动脉狭窄患者显示982条血管,经头颈部CTA联合三维重建技术与DSA检查的符合率为86.97%(854/982),118例脑血管动脉狭窄患者显示颅内侧支动脉1422条,经头颈部CTA联合三维重建技术与DSA检查的符合率为97.54%(1387/1422)。结论针对脑血管疾病动脉狭窄患者,以经头颈部CTA联合三维重建技术进行检查,对患者血管病变的分布情况、动脉狭窄程度的检查效果较好,能够有效分辨患者侧支循环等级,为后续的治疗提供参考依据。Objective Analyze the characteristics of cerebrovascular diseases and the diagnostic value of CT angiography(CTA)combined with 3D reconstruction technology in the diagnosis of arterial stenosis in cerebrovascular diseases.Methods 118 patients with cerebral vascular disease arterial stenosis admitted to our hospital between August 2021 and August 2022 were selected for observation.All patients underwent head and neck CTA examination,and the obtained images were subjected to maximum density projection and vascular 3D reconstruction.The results of digital subtraction angiography(DSA)were used as the"gold standard"to analyze the diagnostic characteristics of head and neck CTA combined with 3D reconstruction,Diagnostic value for patients with cerebral vascular disease arterial stenosis.Results Using DSA examination results as the"gold standard",the combination of head and neck CTA and 3D reconstruction technology has higher sensitivity,specificity,accuracy,positive and negative predictive values for patients with cerebral vascular artery stenosis.118 patients with cerebral vascular artery stenosis showed 982 blood vessels,and the conformity rate between head and neck CTA combined with 3D reconstruction technology and DSA examination was 86.97%(854/982).In 118 patients with cerebral vascular artery stenosis,1422 medial cranial branches were displayed,and the conformity rate between head and neck CTA combined with 3D reconstruction technology and DSA examination was 97.54%(1387/1422).Conclusions For patients with cerebral vascular disease and arterial stenosis,the use of head and neck CTA combined with 3D reconstruction technology for examination can effectively distinguish the distribution of vascular lesions and the degree of arterial stenosis,and provide reference for subsequent treatment.
