Effect of maternal age and miscarriage number on karyotype analysis of chorionic villus in recurrent spontaneous abortion
摘要
Abstract
Objective;To investigate the chromosomal aberration in the abortus of re-current spontaneous abortion. Methods: From Jan. 2008 to Dec. 2011, chromosomal analysis was performed on products of conception of 235 pregnancies with early pregnancy loss. The frequen-cy and type of chromosomal anomalies in recurrent spontaneous abortion and sporadic abortion were compared. The frequency of embryonic chromosomal anomalies in relation to the number of miscarriage were analyesd. Results; Chromosomal abnormality rate in recurrent spontaneous a-bortion group was lower compared with sporadic abortion group (47. 2% vs 70. 9% ,P<0. 05). The frequency of trisomy in recurrent spontaneous abortion group was higher than that of spo-radic abortion group (66. 1% vs 44. 8% ,P<0. 05 ) . The frequency of abnormal embryonic kar-yotypes significantly decreased with the number of spontaneous abortion ( X2 = 15. 266, P= 0.004). The abnormal embryonic karyotype in women aged ≥35 years old was higher than that in women aged<35 years old (P<0.05). Conclusion: Chromosomal anomaly is a major reason of recurrent spontaneous abortion. The frequency of abnormal embryonic karyotype significantly decreases with the number of abortion. Advancing maternal age is a risk factor for abnormal em-bryonic karyotype.关键词
