Ectopic pregnancy is a well-known complication of in vitro fertilization/embryo transfer (IVF-ET). Although ectopic pregnancy after IVF-ET in patients with prior bilateral salpingectomy is uncommon, it can occur and may be a cornual implantation. Because of the possibility of early rupture with severe hemorrhage, special attention to cornual pregnancy after IVF-ET is warranted.
Three cases of cornual pregnancy occurred after IVF-ET. Two of these patients had prior bilateral salpingectomy, whereas another had prior tuboplasty for tubal disease.
Patients who had prior salpingectomy or tuboplasty with cornual patency undergoing IVF-ET are at risk for cornual pregnancy. Close monitoring of pregnancies in these patients is important to prevent a deleterious delay in treatment of a cornual pregnancy.
异位妊娠是体外受精/胚胎移植（IVF-ET）的一种众所周知的并发症。虽然既往双侧输卵管切除术患者在IVF-ET后发生异位妊娠并不常见，但仍可能发生，且可能为宫角妊娠。由于早期破裂并伴有严重出血的可能性，IVF-ET后宫角妊娠值得特别关注。
3例IVF-ET后宫角妊娠。其中2例患者既往有双侧输卵管切除术，另一例曾因输卵管疾病行输卵管成形术。
既往有输卵管切除术或输卵管成形术且宫角通畅的患者在接受IVF-ET时有发生宫角妊娠的风险。密切监测这些患者的妊娠情况对于防止宫角妊娠治疗的有害延迟很重要。
