【摘要】：目的分析320排CT动态容积扫描技术在复杂性先天性心脏病右室双出口(DORV)中的诊断价值。方法收集第三军医大学新桥医院经手术证实的DORV 78例,A组病例36例,行320排CT动态容积扫描,采用心脏节段分析法分析CT图像,B组病例42例,行传统64层CT扫描;比较两种方法的诊断准确率。结果 320排CT动态容积扫描诊断36例右室双出口,与手术结果一致。43例对照组B组的诊断准确率为90.7%,与A组比较差异无统计学意义(P0.05)。78例DORV均合并有室间隔缺损,合并肺动脉狭窄56例,房间隔缺损34例,肺动脉高压21例,动脉导管未闭16例,主动脉缩窄9例。结论 320排CT动态容积扫描对诊断先天性心脏病DORV具有重要的价值。
[Abstract]:Objective to analyze the diagnostic value of 320-slice CT dynamic volume scan in the diagnosis of right ventricular double outlet volume (DORV) of complex congenital heart disease.Methods Thirty-six patients in group A of 78 cases of DORV proved by operation in Xinqiao Hospital of third military Medical University were examined by dynamic volumetric scan of 320 slice CT. 42 cases of group B were analyzed by cardiac segmental analysis, and the traditional 64-slice CT scan was performed.The diagnostic accuracy of the two methods was compared.Results Thirty six cases of right ventricular double outlet were diagnosed by 320 slice CT dynamic volumetric scanning. The accuracy of diagnosis in 43 cases of control group B was 90.7. There was no significant difference between group A and group A (P 0.05). 78 cases of DORV complicated with ventricular septal defect (VSD).There were 56 cases of pulmonary artery stenosis, 34 cases of atrial septal defect, 21 cases of pulmonary hypertension, 16 cases of patent ductus arteriosus and 9 cases of coarctation of aorta.Conclusion 320-slice CT dynamic volume scan is of great value in the diagnosis of congenital heart disease (DORV).
