Ectopic pregnancy implanted in a previous cesarean section scar: experience in the Brazilian Extreme North

Introduction: Ectopic pregnancies (EP) are challenges in obstetric practice due to the potentially fatal complications, especially massive hemorrhage and uterine rupture. Although in most cases of EG the blastocyst implants in the uterine tube, it is possible to have implantation in several places in the body - called extra-tubal ectopic, occurring implantation in the abdomen, ovary, cervix, peritoneal cavity, among other possibilities. A rare site of implantation is the scar tissue from previous cesarean sections - also called cesarean section pregnancy (CSP) and it represents an incipient concern in our environment because the increase in cases is closely related to the increase in cesarean sections performed. Diagnosis and treatment protocols are not unanimous among medical authorities and there is a scarcity of case reports on this condition and its management, justifying the development of this study. Objective: To report a case of ectopic pregnancy by implantation in the uterine scar of a previous cesarean section, attended in a medical service in Macapá (AP), Brazil. Method: From data collected by consulting the patient's medical records, the case report is structured in order to present and discuss it based on the reading of scientific publications on the same theme.
