ABSTRACT
OBJECTIVE@#To explore the relationship between chromosome anomaly and spontaneous abortion, and to provide useful information for genetic counseling and prenatal diagnosis in reproductive clinic.@*METHODS@#A total of 1 780 patients who had a history of spontaneous abortion before 24 weeks of gestation were enrolled. The lymphocyte culture and harvest were performed according to standard methods. Karyotypes were analyzed by G-banding in all cases and C- banding in some cases in addition.@*RESULTS@#Altogether 57 abnormal karyotypes were found and the overall incidence of chromosomal abnormalities was 3.20% (women 3.32%; men 2.12%). Among them 23 cases were the balanced translocation; 14 cases were the Robertsonian translocation, 3 cases were the complex chromosomal rearrangement, and the other 17 cases were the other abnormalities. In women with 1, 2, 3 or more spontaneous abortion, the incidence of chromosomal abnormalities was 1.7%, 2.3%, and 5.8%, respectively.@*CONCLUSION@#Translocations are the major abnormal karyotpes associated with spontaneous abortions. The chance of finding chromosomal aberration increases with the number of abortions. Chromosomal abnormalities are more common in women with 3 or more spontaneous abortions.
