围产期死亡是受社会、环境、产科和遗传因素的影响。染色体异常是遗传因素中重要的组成部份,但是这方面的资料不多。作者报告了500例围产期死亡的染色体分析结果。作者从1978年11月至1981年3月,根据死亡时期分类收集标本:(1)妊娠20～28周死胎130例,完成染色体分析106例,异常4例(3.8%);(2)围产期死亡即妊娠大于28周的死胎或生后7天以内死亡416例,完成染色体分析357例,异常17例(4.8%);
Perinatal deaths are affected by social, environmental, obstetric and genetic factors. Chromosomal abnormalities are an important part of the genetic factors, but there is not much information on this. The authors report the chromosome analysis of 500 perinatal deaths. From November 1978 to March 1981, the authors collected specimens according to their age of death: (1) 130 stillbirths from 20 to 28 weeks of gestation were completed and chromosome analysis was performed in 106 and 4 cases (3.8%); (2) Perinatal 416 cases of stillbirth, or stillbirth of more than 28 weeks of gestation, or death within 7 days of birth, 357 cases of complete chromosome analysis and 17 cases of abnormality (4.8%) were completed.
