Implantation of a pregnancy within the scar of a previous cesarean delivery is the rarest of ectopic pregnancy locations. Only 19 cases have been reported in the English medical literature since 1966. If diagnosed early, treatment options are capable of preserving the uterus and subsequent fertility. However, a delay in either diagnosis or treatment can lead to uterine rupture, hysterectomy, and significant maternal morbidity. Although expectant and medical managements have been reported, termination of a cesarean scar pregnancy by laparotomy and hysterotomy, with repair of the accompanying uterine scar dehiscence, may be the best treatment option.
