胎儿股骨短小的临床诊疗分析(附276例病例报告)

How to diagnose and deal with the pregnancies with short femurs in fetuses(with 276 cases report)

目的分析总结临床常见的胎儿股骨短小的诊断思路。方法结合2005年1月至2007年4月间,我院产前超声测得的胎儿股骨径对应的孕周比实际孕周小1w以上的276份病例,对比分析其妊娠结局。结果276份病例中,最常见的是正常胎儿合并轻度的股骨短(≤2w),其次见于胎儿发育迟缓(FGR),占24.28%。我们还发现了26例致死性骨发育不良和5例非致死性骨发育不良引起的严重股骨短小。我们观察的病例中,有3例21-三体胎儿仅仅表现为股骨短小。结论产前发现胎儿股骨短小,需结合多项指标、病史综合考虑,从而做出正确判断和准确处理。

Objective： To analyze and summarize how to diagnose and deal with the pregnancies with short femurs in fetus. Methods ： To review 276 cases whose femurs were short for their age （≥1 week） found in our hospital from January 2005 to April 2007. We compared the results of postnatal following - up with prenatal diagnosis. Results： In our report cases, most fetuses were normal and their femurs were slightly short （≤2w）. 24. 28 % cases were caused by FGR. We also found that 26 cases with lethal skeletal dysplasia and 5 cases with non - lethal skeletal dysplasia accompanied seriously short femurs. There were 3 fetuses with tirsomy 21. Conclusion： When we find a fetus＇s femurs is short for it＇s age, we should consider multiple indexes and synthesize the history, the results of other examination, then we can judge and deal with the case correctly.
