法鲁氏四联症(Fallot’s tetrad,以下简称FT)的传统确诊方法是进行右心导管及X 线心血管造影检查.上述方法为创伤性检查,不便于重复应用.近年来,国内外已相继开展应用二维超声心动图结合声学造影的方法诊断FT.本文应用二维超声心动图结合双氧水声学造影对27例FT 患儿进行检查,并与心导管、X 线心血管造影及手术资料进行了对比分析,现将结果报告如下. Fallot’s tetrad (hereinafter referred to as FT) is the traditional diagnosis of right heart catheterization and X-ray angiography. The above method is traumatic examination, inconvenient for repeated use. In recent years, both at home and abroad have been To carry out the application of two-dimensional echocardiography combined with acoustic contrast method to diagnose FT.Two-dimensional echocardiography combined with hydrogen peroxide acoustic imaging in 27 cases of FT were examined and with cardiac catheterization, X-ray angiography and surgical data were Comparative analysis, the results are reported below.
