为了解心血管造影定量测量先天性心脏病大血管的准确性及价值 ,对 36例先天性心脏病患者行右心造影和B超检查 ,并测量主、肺动脉及室间隔缺损口径值。结果显示右心造影测得主、肺动脉主干及室间隔缺损口径值分别为(2 1.6 4± 5 .0 5 ) ,(11.41± 4.16 ) ,(12 .90± 3.90 ) mm,B超测得值分别为 (2 5 .77± 5 .2 5 ) ,(11.77± 3.6 1) ,(13.6 0±5 .6 0 ) mm,无明显统计学差异。认为利用血管造影机心脏软件包可准确测量右心造影各大血管及室间隔缺损大小 ,从而为术前评价手术风险性提供参考 To understand the accuracy and value of cardiovascular angiography in the quantitative measurement of large vessels of congenital heart disease, 36 patients with congenital heart disease underwent right ventricular angiography and B-mode ultrasound examination, and measured the diameter of the main pulmonary artery and ventricular septal defect. The results showed that the diameters of the main and pulmonary artery and ventricular septal defect measured by right heart angiography were (2 1.6 4 ± 5 ​​.0 5), (11.41 ± 4.16) and (12.90 ± 3.90) mm, respectively. (2 5 .77 ± 5 .2 5), (11.77 ± 3.6 1), (13.6 0 ± 5.60) mm, no statistically significant difference. That the use of angiography machine cardiac software package can accurately measure the right ventricular angiography of the major vessels and ventricular septal defect size, so as to provide a reference for preoperative evaluation of surgical risk
