摘　　要：目的:通过比较自然受孕和辅助生殖技术(ART)受孕先兆流产患者的妊娠结局,探讨影响ART妊娠成功率的相关因素。方法:选取2006年1月～2009年12月因早孕先兆流产住院的患者,根据不同受孕方式分为自然受孕组和ART受孕组两组,对其临床资料进行回顾性分析。结果:ART受孕组的年龄较自然受孕组大,差异有统计学意义(P<0.05);ART受孕组宫腔操作次数较自然受孕组多(P<0.05);ART受孕组的双胎妊娠率较自然受孕组高(P<0.05);ART受孕组妊娠成功率较自然受孕组低(P<0.05);ART受孕组妊娠晚期并发症、剖宫产率较自然受孕组高(P<0.05)。结论:年龄、多胎妊娠、多次宫腔操作是影响ART妊娠成功率及妊娠晚期并发症的主要因素。在辅助生殖技术中要减少多胎妊娠的发生,规范临产操作技术,注意宫颈机能的保护。有多次宫颈操作史者,妊娠期应严密监测宫颈情况,必要时行宫颈环扎术。Objective：To explore the related effect factors of pregnancy success rate of assisted reproductive technology（ART） by comparing the pregnancy outcomes of patients with threatened abortion of natural conception and ART.Methods：The patients with threatened abortion were selected from the hospital from January 2006 to December 2009,then they were divided into natural conception group and ART conception group according to different conception modes,and their clinical data were analyzed retrospectively.Results：The maternal age of ART conception group was older than that of natural conception group（P0.05）;the times of intrauterine operation in ART conception group was more than that in natural conception group（P0.05）;the rate of twin pregnancy in ART conception group was higher than that in natural conception group（P0.05）;the success rate of pregnancy in ART conception group was lower than that in natural conception group（P0.05）;the incidence of complications during the third trimester of pregnancy and the rate of cesarean section in ART conception group were higher than those in natural conception group（P0.05）.Conclusion：Age,multiple pregnancy and repeated intrauterine operation are the main effect factors of success rate of pregnancy and incidence of complications during the third trimester of pregnancy of cases adopting ART.In ART conception group,the occurrence of multiple pregnancy should be reduced,the lying-in operation techniques should be normalized,and the cervical function should be protected.For the cases with the history of repeated intrauterine operation,the cervical situation should be monitored closely,cervical cerclage may be performed if necessary.
