摘要
胚胎移植是人类辅助生殖技术中的重要环节,最佳胚胎放置位置的选择是影响试管婴儿妊娠率的关键因素。二维超声引导下胚胎移植已成为目前标准化的移植技术,但不能确认胚胎在宫腔的空间位置;三维超声可观察宫腔形态,明确胚胎放置位置;四维超声则可实时指导胚胎移植,选择个性化的移植位点,进一步提高移植技术。综述超声引导下胚胎移植与胚胎放置位置的文献,以利于指导胚胎移植并选择最佳移植位点。
Embryo transfer (ET) is one of the most important elements of assisted reproductive technology (ART), and the optimized location of embryo placement is the key influencing factor of the pregnancy rate of test tube baby. ET guided by two-dimensional (2D) ultrasound has become the currently standardized transfer technology. However it couldn't make sure the location of embryo in uterine cavity. Three-dimensional (3D) ultrasound could observe cavity morphous and make sure the embryo location. And the four-dimensional (4D) sonography could further improve transfer technology with the instruction of ET real time and the select of individual site of transfer. This article reviews the papers about ultrasound-guided ET and embryo location in order to promote the instruction of ET and the select of the optimized ET site.
