摘　　要：目的探讨高频超声检查胎儿尸体心脏的方法与价值。方法应用高频超声对71例引产后胎儿尸体心脏进行多切面扫查,并采用辅助方法即经胎儿脐静脉或直接用注射器向心腔内注水后再次行超声扫查。对比分析胎儿尸体心脏高频超声检查及尸检结果。结果在71例胎儿尸体标本中高频超声检查成功36例,成功率为50.7%(36/71),其中17例检测出心脏畸形(共37处心脏结构异常),与产后尸体解剖结果相比较30处相符,产后尸体高频超声正确诊断率81.08%(30/37),漏误诊率18.92%(7/37)。结论可应用高频超声检查胎儿尸体心脏,必要时可采用辅助方法,如心脏检查成功,诊断准确率较高。对由于家属拒绝尸检者,判断胎儿心脏产前超声诊断准确性具有非常重要的意义。Objective To explore the method and value of the high frequency ultrasound on the postnatal fetus with corpse heart. Methods The mutli-cross-section screening method was used to examine the induced abortion fetus corpse hearts before and after affusion into heart intracavitary through umbiliean vein. The results were compared with the autopsy results. Results The 36 fetus hearts in total 71 cases were successfully examined and the achievement ratio was 50.7%. The cardiac anomalies were found in 17 cases of the 36 eases. There were 37 cardiac constretion abnormalities in 17 eases. Compared with the results autopsy, the aecuracy of diagnosis was 81.08% （30/37）and the misdiagnosis was 18.92% （7/37）about the postnatal high frequency ultrasound examination. Conclusions A high accuracy was approved with the method even though the 50.7% of postnatal high frequency was achieved. It is meaningfully important to evaluate the accuracy of prenatal ultrasound examination of fetus heart for the ones who refuse autopsy .
