摘要
目的：研究畸形胎儿尸体高频超声检查准确性与可靠性。方法：对2006年12月～2007年10月在我院行产前超声检查诊断为严重畸形或染色体检查异常并在该院引产且其父母同意尸体解剖的71例引产胎儿行产后高频超声检查，并将结果与尸体解剖对比。结果：产后超声诊断与尸体解剖的符合率为91．49％（129／141），产后超声漏误诊12处（8．51％），从不破坏尸体完整性、操作的简便性、获得结果的快捷性方面进行评估，产后超声优于尸体解剖17处（12．06％）。产前超声与产后超声诊断准确率差异有统计学意义，P〈0．05。产后超声较产前超声多发现畸形29处（20．57％），产后超声纠正产前超声误诊的11处（7．80％）。结论：产后超声可以作为尸体检查的选择方法之一，或在胎儿尸体解剖遇到障碍时代替运用，或在尸体解剖前运用作为尸体解剖思路、步骤、方法等的指导。
Objective：To approach file accuracy and reliability of postmortem fetus ultrasound （PMFU） by comparing results with that from autopsy. Methods： 71 fetuses, who were performed prenatal ultrasound examination in Shenzhen Maternity and Child Heahhcare Hospital from December 2006 to October 2007 and were diagnosed of malformation or clrromesome abnormalities, were terminated there and their parents agreed to anatomy. These fetuses were performed PMFU and the results were compared with those from autopsy. Re- sults：The coincidence rate was 91.49% （129/141） for PMFU and autopsy, among which 17 malformations PMFU did better than autop- sy, Considering the integrity of corpse and the convenience of operation, the time-consuming of autopsy results. The other 8.51% were misdiagnosed. The difference of fetus malformations detection rate between PMFU and Pre-U was of statistic value, P 〈 0. 005. PMFU found 29 malformations more titan PU and corrected 11 malformations. Conclusion： PMFU can serve as a alternative manner of corpse exantination. PMFU can be used when autopsy is confused or to guide autopsy.
