宫腔镜在胚胎反复种植失败病例中的临床应用价值

胚胎反复种植失败(repeated implantation failure,RIF)已成为实施体外受精-胚胎移植(in vitro fertilization embryo transfer,IVF-ET)技术中的难点。在RIF中,胚胎因素只占不到40%,子宫内膜因素占60%以上,而宫腔镜作为诊断宫腔病变的金标准,除能直视宫腔病变外,还能对病变部位进行活检和处理,改善宫腔内环境,从而提高RIF患者的胚胎种植率和临床妊娠率。

Repeated implantation failure(RIF)has become the technical difficulty of IVF-ET.In RIF,endometrial factors account for more than 60%,while embryo factors account for less than 40%.As the gold standard for diagnosing uterine lesions,hysteroscopy can not only offers direct visualization of lesions in the uterine cavity,but also can perform biopsy and treatment,which has great value in improving the embryo implantation rate and clinical pregnancy rate.
