摘　　要：目的探讨三维超声心动图(3DE)在圆锥动脉干畸形(CTD)室间隔缺损(VSD)定量研究中的准确性及其临床意义。方法2000年5月至2003年11月在上海儿童医学中心住院且二维超声心动图(2DE)、经胸3DE、心血管造影及手术等定量测量结果完整的CTD患儿共63例,将3DE测量结果与2DE、造影及手术测值对比。结果方差分析、SNK均数间两两比较及相关分析显示,3DEVSD长径测值为1.69cm(从右室面)和1.63cm(从左室面),虽较手术测值(1.84cm)低估,但低估程度小于2DE测值(1.27cm)及造影测值(1.12cm);3DE与手术测值的相关性(r=0.74)明显高于2DE(r=0.39)及造影测值(r=0.25)。3DEVSD短径测值与造影测值相接近,两者比较无统计学差异(P>0.05)。3DEVSD短径测值与2DE及造影测值的相关性(r=0.45,r=0.54)高于3DEVSD长径测值与2DE及造影测值的相关性(r=0.37,r=0.44)。3DEVSD面积测值与手术测值呈良好相关(r=0.57)。结论3DE可作为CTDVSD定量分析的又一无创手段,能提供较2DE更准确的定量诊断。Objective To evaluate the accuracy and clinical value of transthoracic three-dimensional echocardiographic (3DE) quantitative analysis in ventricular septal defect (VSD) of conotruncal defects (CTD).Methods From May 2000 to November 2003 in Shanghai Children Medical Center,there were 63 inpatients of CTD with all quantitative findings measured by 3DE,two-dimensional echocardiography (2DE),angiocardiography and surgical findings.Their measurements of VSD sizes and areas with 3DE were compared with those with 2DE,angiocardiography and surgical findings.Results From the analysis of variance,Student-Newman-Keuls (SNK) test and correlation analysis,the measurements of VSD long diameter (mean 1.69cm in en-face view of ventricular septa from right ventricle and 1.63 cm in en-face view of ventricular septa from left ventricle) with 3DE was less than the measurements of VSD diameter (mean 1.84 cm) with surgical findings,but they were better correlated with those with surgical findings ( r =0.74) than the measurements of VSD diameter (mean 1.27 cm) with 2DE ( r =0.39) and those (mean 1.12 cm) with angiocardiography ( r =0.25).However,the measurements of VSD short diameter with 3DE was close to those with angiocardiography,and there was no significant difference ( P >0.05) between them.The measurements of VSD short diameter with 3DE were better correlated with those with 2DE and angiocardiography than the measurements of VSD long diameter with 3DE.Meanwhile,the measurements of VSD area with 3DE were well correlated with the measurements of VSD diameter with surgical findings (r=0.57) .Conclusion 3DE can provide more accurate quantitative diagnosis in CTD VSD than 2DE.
