应用3D-CTA技术术前评估脑动脉瘤的临床意义

Clinical Significance of 3D-CTA Technology in Evaluating Cerebral Aneurysm before Operation

目的 分析3D-CTA技术术前评估脑动脉瘤的临床意义。方法 回顾分析,收集本院2017年3月至2019年9月收治的65例脑动脉瘤患者的临床资料为研究对象,所有患者均进行DSA及3D-CTA检查。对患者所得图像进行分析,以DSA检查结果为基准,计算3D-CTA技术对脑动脉瘤的检出准确率,以及3D-CTA不同技术显示脑动脉情况。结果 DSA确定65例脑动脉瘤患者共71个,其中≤5mm小动脉瘤有21个,5mm~10mm中等动脉瘤34个,≥10m大m动脉瘤16个;3D-CTA技术对脑动脉瘤的检出准确率为97.18,与手术及DSA检查比较无差异,符合率高(P>0.05);3D-CTA原始图像、MPR对小动脉瘤检出率为0,VR检出最高为90.47%;中等动脉瘤原始图像、MPR检出率最低,SSD、MIP、VR检出率均为100.00%;3D-CTA不同技术显示对大动脉瘤检出率均为100.00%。结论 3D-CTA对脑动脉诊断准确性高,操作简方便,可为临床手术治疗提供更全面的信息。

Objective To analyze the clinical significance of 3D-CTA technology in evaluating cerebral aneurysm before operation. Methods The clinical data of 65 patients with cerebral aneurysm treated in our hospital from March 2017 to September 2019 were collected for retrospective analysis. All patients were examined by DSA and 3D-CTA. The images of the patients were analyzed. The results of the DSA test were used as a benchmark to calculate the accuracy of 3D-CTA in detection of cerebral aneurysms.The condition of cerebral arteries shown by 3D-CTA technique was compared. Results 71 cerebral aneurysms were identified by DSA in 65 cases, including 21 small aneurysms ≤5mm, 34 medium aneurysms 5mm-10mm, and 16 large aneurysms ≥10m. The detection rate of 3D-CTA technology for cerebral aneurysms was 97.18, and Compared with surgery and DSA examination, there was no difference and the coincidence rate was high(P>0.05). The detection rate of 3D-CTA original images and MPR for small aneurysms was 0 and the highest detection rate of VR was 90.47%;The detection rate of original images of medium aneurysms and MPR was the lowest, and the detection rates of SSD, MIP, and VR are 100.00%. Different 3D-CTA technologies showed that the detection rate of aortic aneurysms was 100.00%. Conclusion 3D-CTA has high accuracy in the diagnosis of cerebral arteries,is simple and convenient, and can provide more comprehensive information for clinical surgical treatment.
