Cesarean scar ectopic pregnancy (CSEP) is a rare type of ectopic pregnancy when the fetal egg attaches to the scar tissue of the uterus after a previous cesarean section (CS).
This review presents the data on the etiology, pathogenesis and incidence of CSEP.  The present study analyzed the risk factors associated with CS surgery and invasive procedures within the uterine cavity following CS. The morphologic forms of CSEP are described. Current methods for diagnosing and treating CSEP with their advantages and disadvantages are presented. The most frequent diagnoses observed in CSEP are vaginal bleeding, large masses on the anterior surface of the uterus, cervico-isthmic pregnancy, missed miscarriage with low location of the fetal egg, incomplete abortion, etc. These findings were obtained from a review of medical literature. This paper describes the complications of this pathology, the most common of which is profuse bleeding. It also studies preventive measures and methods of rehabilitation for this type of ectopic pregnancy.
Conclusion: CSEP is a rare but potentially life-threatening complication following CS. Understanding the etiology and pathogenesis of this condition should be relevant today for a practicing obstetrician-gynecologist and doctors of other specialties. Therefore, it is essential to ensure the accuracy of pregnancy diagnosis, minimize performing unreasonable CS, provide reliable treatment, and be sure to carry out rehabilitation after CSEP.
