目的探讨染色体异常与不良妊娠的关系。观察遗传因素在不良妊娠患者中的重要性。方法检测1500例妊娠不良患者外周血淋巴细胞染色体核型。采用外周血淋巴细胞培养,常规制片,G显带,染色体核型分析。结果检出染色体多态核型71例。结论染色体形态异常与不良妊娠有关。 Objective To investigate the relationship between chromosomal abnormalities and adverse pregnancy. Observe the importance of genetic factors in patients with adverse pregnancy. Methods The karyotypes of peripheral blood lymphocytes in 1500 cases with poor pregnancy were detected. Using peripheral blood lymphocyte culture, conventional production, G banding, chromosome karyotype analysis. Results Chromosome polymorphism karyotype detected in 71 cases. Conclusion Chromosome abnormalities are associated with adverse pregnancy.
