摘要
应用二维超声心动图及彩色多普勒血流显像技术对112例室间隔缺损病例进行定位诊断和缺损孔大小定量并与手术所见对照分析。结果表明,超声心动图对室缺的正确定位诊断有赖于对超声切面的选择,以及辨认室缺与心内特征性解剖结构的空间位置关系;二维超声心动图对小室缺孔径测量存在低估,对较大室缺孔径测量较为准确;彩色多普勒血流显像对小室缺孔径测值存在高估而对大室缺孔径测值则低估。
A study on localization of ventricular septal defect(VSD)and measurement of the diameter of VSD was performed in 112 patients comfirmed operatively by 2D-echocardiography and Color-coded Doppler flow imaging(2D-CDFI),respectively.The results show that correct localization of VSD is de- pendent on identifying the spatial relation between VSD and characteristic intracardiac structures on the proper views;that 2DE underestimates the diameter of small VSDs and accurately estimates that of large VSDs,while CDFI overestimates the size of small VSDs amd underestimates that of large VSDs.
