The number of pregnancies, number of miscarriages, human chorionic gonadotropin (HCG) before curettage, duration of medication before UAE, and hemorrhage after UAE were not significantly correlated with the occurrence of moderate to severe pain after UAE (P > 0.05). The volume of gestational sac and days of gestation were responsible for the occurrence of moderate to severe pain after UAE (P < 0.05), with the former being the main influencing factor, and these explained 8.3% of the total variance.Conclusion: Moderate to severe pain occurred commonly in patients with CSP undergoing UAE. In clinical care of patients with CSP who are going to undergo UAE, data concerning the volume of gestational sac and days of gestation should be considered for anticipatory pain assessment, and interventions should be implemented as early as possible to reduce the pain and improve the experience of care.Keywords: cesarean scar pregnancy, uterine artery embolization, moderate to severe pain, research
