胎儿颜面部畸形高频超声尸体解剖学研究

目的研究胎儿尸体颜面部畸形产后高频超声检查的准确性。方法对产前超声检查诊断为严重畸形或染色体检查为异常而引产、且其父母同意尸体解剖的71例引产胎儿颜面部行产后高频超声检查，并将结果与尸体解剖对比。结果产后超声发现71例中共有24例胎儿存在颜面部畸形，共有颜面部畸形51处，经尸体解剖证实，PMFU灵敏度、准确率均达100％。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，51处颜面部畸形中，PM—FU在22处优于尸体解剖。结论产后超声检查为胎儿尸体解剖学检查开辟了新领域，可以作为尸体检查的选择方法之一，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。

Study on high frequency ultrasound autopsy of fetal facial malformations

Objective To discuss the reliability of postmortem fetal ultrasound (PMFU) examination of facial malformations. Methods Seventy-one fetuses that diagnosed malformations or chromosome abnormalities,by prenatal diagnosis were terminated, and the results of PMFU were compared with autopsy. Results A total of 51 facial malformations were found in 24 fetuses with PMFU, the sensitivity was 100%, and the coincidence rate was 100%, compared with autopsy. Considering the integrity of corpse and the convenience of operation the time-consuming of autopsy results, PMFU was better than autopsy in the examinations of 22 malformations. Conclusion PMFU opens up a new territory of fetal corpse examination. PMFU can serve as an alternative of corpse examination in the diagnosis of fetal facial malformations.
