摘　　要：目的分析双绒毛膜三胎妊娠行减胎术后的妊娠结局。方法回顾性分析2007年1月至2011年1月在广西医科大学第三附属医院生殖中心经辅助生殖技术治疗受孕的20例多胎妊娠的临床资料,其中双绒毛膜三胎妊娠7例（A组）,三绒毛膜三胎妊娠13例（B组）均于移植后33～56 d行减胎术,减灭1胎,保留2胎。比较两组自然胎儿丢失率、分娩率、婴儿畸形率。结果 A组的自然胎儿丢失率、婴儿畸形率显著高于B组（64.3%比19.2%,40.0%比0%）,差异有统计学意义（P〈0.05）,两组分娩率（42.9%比83.3%）比较差异无统计学意义（P〉0.05）。结论为了避免对妊娠结局的不良影响,双绒毛膜三胎妊娠减胎时宜减灭单绒毛膜双胎,保留单绒毛膜单胎。Objective To analyze the outcome of triplet pregnancies after trans-vaginal multifetal reduction. Methods Clinical data of 20 patients with multiple pregnancies under assisted reproductive technology in Reproduction Center of the Third Affiliated Hospital of Guangxi Medical University from Jan. 2007 to Jan.2011 were analyzed retrospectively. Among all the cases,7 cases were dual-chorionic triplet pregnancies（ group A）,and 13 cases were triple-chorionic triplet pregnancies（ group B）. The rates of spontaneous pregnancy reduction,delivery and baby abnormality of the two groups were compared. Results The rates of spontaneous pregnancy reduction and baby abnormality of group A were higher than group B（ 64. 3% vs 19. 2%,40. 0% vs 0%）,the differences were statistically significant（ P 0. 05）. The delivery rate of group A was obviously lower than group B（ 42. 9% vs 83. 3%）,but the difference was not statistically significant（ P 0. 05）. Conclusion In order to avoid the adverse effects on pregnancy outcome,it is better to reduce monochorionic twin pregnancies,and keep the mono-chorionic single pregnancy for the dual-chorionic triplet pregnancies.
