The results show that transvaginal sonography offers highly accurate diagnoses of heterotopic cesarean scar pregnancy during the first trimester. Careful exclusion of cesarean scar pregnancy is of great clinical importance for patients with a history of cesarean section after in vitro fertilization\u2010embryo transfer, even when an intrauterine pregnancy has been detected. We recommend single embryo transfer for patients with a history of cesarean section. Expectant management may provide the opportunity for a live cesarean scar pregnancy to develop, albeit at high risks of placenta accreta and hemorrhage, and this needs further verification in the future.<\/jats:p>","DOI":"10.1002\/jum.15610","type":"journal-article","created":{"date-parts":[[2021,1,20]],"date-time":"2021-01-20T14:22:42Z","timestamp":1611152562000},"page":"2239-2249","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Heterotopic
