自然流产的原因之一是染色体异常。六十年代初期Carr指出:胎儿染色体异常是造成胚胎早期坏死的重要原因。现将1980年以来查到的国内资料加以归纳,并进行分析,讨论,有助于了解我国习惯性流产夫妇染色体异常的核型。资料来自1980年以来国内文献报道62种异常核型(未包括尚未定号、未定位、微小变化及正常变异在内),以其所牵涉到的染色体的最小号次为序,归纳 One of the causes of spontaneous abortion is chromosomal abnormalities. Carr pointed out early in the sixties: fetal chromosomal abnormalities is an important cause of early embryonic necrosis. At present, the domestic data obtained since 1980 are summarized, analyzed and discussed, which helps to understand the karyotype of chromosomal abnormalities in couples with habitual abortion in our country. Data from the domestic literature since 1980 reported 62 kinds of abnormal karyotype (not yet included Dingding, not positioning, small changes and normal variation included), with the chromosomes involved in the order of the smallest number, summarized
