卵巢妊娠是一种罕见的异位妊娠亚型，其机制尚不清楚。我们报告一例卵巢妊娠，支持囊胚迁移机制。在一个新的非供体周期中，在体外受精后进行单个囊胚移植后，不孕妇女怀孕了。经阴道超声显示右侧卵巢黄体附近有一个孕囊样结构，内含一个活动胎儿。腹腔镜检查发现卵巢内一个红色肿胀的着床部位，通过楔形切除完全切除，未损伤剩余的实质。本病例表明，移植到子宫内膜腔内的新鲜囊胚通过输卵管迁移，植入卵巢表面，形成卵巢妊娠。
Ovarian pregnancy is a rare subtype of ectopic pregnancy, and its mechanisms have not been clarified. We report a case of ovarian pregnancy that supports a blastocyst migration mechanism. An infertile woman became pregnant after a single blastocyst transfer following in vitro fertilization during a fresh non-donor cycle. Transvaginal ultrasound revealed a gestational sac-like structure containing an active fetus that was located adjacent to the corpus luteum of the right ovary. Laparoscopy identified a red, swollen implantation site in the ovary, which was completely removed by wedge resection without damaging the remaining parenchyma. This case demonstrated that a fresh blastocyst transferred into the endometrial cavity migrated through the fallopian tube, implanted on an ovarian surface, and formed an ovarian pregnancy.
