孕早期产前诊断的发展正为大家所重视。如在孕6～12周确诊胎儿异常,进行治疗性流产只需施行简单的吸刮术便可,既减轻母体精神上和身体上的负担,又避免某些中期妊娠引产时可能引起的严重的并发症。六十年代末,已有人试图以绒毛组织为材料进行孕早期产前诊断。但这些早期的尝试由于不能安全、可靠地获得绒毛组织而中断。近年来,随着产前诊断技术的发展及超声设备的迅速普及,产前诊断有向孕早期发展的趋势。现将有关研究综述如下。 Prenatal diagnosis of early pregnancy is for everyone’s attention. If pregnant 6 to 12 weeks confirmed fetal abnormalities, the treatment of abortion, simply the implementation of simple suction curettage can not only reduce the mental and physical burden on the mother, but also to avoid some of the mid-pregnancy induced labor may cause serious complication. In the late 1960s, an attempt was made to use villous tissue as a material for the first trimester of prenatal diagnosis. However, these early attempts were interrupted by the inability to obtain villus tissue safely and reliably. In recent years, with the development of prenatal diagnostic techniques and the rapid popularization of ultrasound equipment, prenatal diagnosis tends to develop in early pregnancy. The relevant research is summarized as follows.
