本文对172例经心导管检查或手术证实有VSD、ASD、PDA及5例误诊者的二维彩色多普勒血流显像(2DCFI)作回顾性分析,结果表明2DCFI是诊断VSD、ASD、PDA的敏感方法,并能迅速显示心内分流的方向、位置及分流束宽度,在VSD及ASD的分型与手术对照上有较高的符合率,通过测量分流束宽度可作半定量诊断。同时分析漏诊及误诊原因,总结2DCFI在LVRAC、PDA鉴别诊断中的作用,指出多个切面及节段性探查可避免漏诊,结合二维超声心动图(2DE)清晰显示心脏解剖结构及追踪异常彩色血流起源可避免误诊。
In this paper, we retrospectively analyzed 172 cases of 2DCDI with VSD, ASD, PDA and 5 cases misdiagnosed by transcatheter catheterization or surgery. The results showed that 2DCFI was a good method to diagnose VSD, ASD, PDA and can quickly display the direction, location and shunt beam width of the shunt in the heart. There is a high coincidence rate between VSD and ASD classification and surgical control. The shunt beam width can be used for semi-quantitative diagnosis. At the same time, the causes of misdiagnosis and misdiagnosis were analyzed. The role of 2DCFI in the differential diagnosis of LVRAC and PDA was summarized. It was pointed out that multiple sections and segmental exploration could avoid misdiagnosis, and 2DE could clearly display cardiac anatomy and abnormal color tracking The origin of blood flow can avoid misdiagnosis.
