摘　　要：目的探讨实时双平面法评价胎儿单纯室间隔缺损(VSD)的临床价值。方法分别采用常规二维超声和实时双平面法筛查胎儿心脏畸形,重点观察室间隔肌部、膜部及漏斗部有无连续中断,同时联合彩色多普勒观察有无穿隔血束,并对两种方法筛查VSD的敏感性进行比较。结果常规二维超声和实时双平面法的敏感性分别为68.42%、86.49%,差异有统计学意义(P<0.05)。结论实时双平面技术不仅能清晰地显示胎儿心脏结构及心脏大血管血流情况,而且提高了胎儿VSD筛查的敏感性,是胎儿期诊断VSD的重要方法之一。Objective To investigate the clinical value of real-time biplanar echocardiography in evaluating fetal simple ventricular septal defects （VSD）.Methods Cardiac abnormalities were screened by conventional two-dimensional echocardiography and real-time biplanar echocardiography. Whether defects exist in muscular part, membranous part and infundibulum part of interventricular septum was determined with the two methods while whether blood flow exist in the above parts was also determined with the two methods combined with Color Doppler. Then the screening sensitivities of the two methods were compared.Results The screening sensitivities of conventional two-dimensional echocardiography and biplanar echocardiography were 68.42% and 86.49%, respectively. There were signiifcant differences between the two methods in diagnosing fetal simple VSD （P〈0.05）.Conclusion Biplanar echocardiography which plays an important role in diagnosing fetal VSD, not only can clearly display fetal heart structures and blood lfow conditions of cardio great vessels, but also can improve the screening sensitivity of fetal VSD.
