Cesarean Scar Pregnancy: A Case Series of Diagnosis, Treatment, and Results

The aim was to collect cases of cesarean scar pregnancy (CSP) and describe the evolution of diagnosis, treatment modalities, and outcome. A retrospective cohort study was conducted of patients who had been diagnosed with CSP. Treatment decision was made according to the type of CSP, levels of beta human chorionic gonadotropin (hCG), and estimated vascularity. Forty cases with CSP were recorded. Overall success of the primary treatment was recorded among 30 of 40 cases (75%) and significantly correlated with degree of vascularity, type of CSP, and beta hCG levels. The treatment methods included serial methotrexate in 20 cases; 15 of them (75%) were successful. In this specific group, we found type 2 scar and high vascularity to be significantly associated with treatment failure. In conclusion, cases with type 2 CSP, high vascularity, and high beta hCG levels should be considered high risk, and extra caution should be taken in choosing treatment modality and follow-up.
