体外受精—胚胎移植后宫外孕的防治——附3例报告

Prevention and Treatment of Ectopic Pregnancy After in Vitro Fertilization-embryo Transfer.

目的:探讨体外受精—胚胎移植(IVF-ET)后宫外孕的预防及处理。方法;对3例IVF-ET后宫外孕进行临床报告及分析。结果:本组IVF-ET26例临床妊娠,3例宫外孕(发生率11.5％)。3例宫外孕均有输卵管因素而作IVF-ET,通过对移植方法改进后,未再发生宫外孕,IVF-ET后宫外孕因有尿hCG及B超的监测,能及早发现,采取保守治疗可取得较好效果。对存在输卵管因素,需要再作IVF-ET者宜作手术治疗,同时切除对侧输卵管。结论:输卵管因素虽是IVF-ET的重要指征,但也是IVF-ET后宫外孕的常见病因,改进移植方法,可减少宫外孕的发生。

Objective: To study the prevention and treatment of ectopic pregnancy after in vitro fertilization-embryo transfer (I VF-ET). Methods: Three cases with ectopic pregnancy after IVF-ET were clinically reported and analysed. Results:Ectopic Pregnancy occurred in 3 patients out of 26 cases of clinical pregnancy,the incidence rate was 11. 5%. With modifying the transfer methods,ectopic pregnancy did not appear later. When the cases had been closely monitored with urine hCG and ultrasound , ectopic pregnancy might be diagnosed earlier, moreover, the good effect was obtained by protective therapy method. Conclusions: Fallopian tubal factors were the important indication of IVF-ET, however, were also the common causes of ectopic pregnancy. With modifying the transfer methods, the incidence rate of ectopic pregnancy would be decreased.
