A technique of fetoscopy and fetoscopic blood sampling is described that makes maximum use of ultrasound scanning. A particle size analyser is also an integral part of the procedure. The results are based on 170 fetoscopies, 85 of which were performed for diagnostic reasons. The anterior placenta is rarely a cause of failure and in many instances makes fetal blood sampling easier. Pure fetal blood is obtainable from the umbilical cord insertion in 95% of cases sampled after 18 weeks' gestation. Fetal mortality may be as low as 3% and long-term adverse sequelae have not yet been discovered.
本文描述了一种充分利用超声扫描的胎儿镜检查和胎儿镜采血技术。粒度分析仪也是该操作不可或缺的一部分。结果基于170例胎儿镜检查，其中85例是出于诊断目的进行的。前置胎盘很少导致手术失败，在许多情况下反而使胎儿采血更容易。妊娠18周后采样的病例中，95%可从脐带插入处获取纯胎儿血。胎儿死亡率可能低至3%，尚未发现长期不良后遗症。
