Abstract
Objective:To investigate the relationship between badness pregnancy and cytogenetics.Method:Chromosomal karyotypes were analyzed in 545 patients with spontaneous abortion or embryo growth ceasing or bearing malformation child history by using G-banding after periphery blood lymphocyte cultured.Results:There were 29 abnormal chromosomal karyotypes in 545 patients.The rate of abnormal karyotypes was 4.9%,including 26 patients(89.7% in abnormal karyotypes) with spontaneous abortion or embryo growth ceasing and 3 patients(10.3% in abnormal karyotypes) with bearing malformation child history;Aberrance of the Chromosomal in 20 patients(3.7% in 545 patients).Conclusion:Chromosomal abnormalities is an important factor of badness pregnancy,So it is necessary to take the examination of chromosomal in patients who had badness pregnancy history.It is benefit for us to give advises.
