Management for delayed diagnosis in cesarean scar pregnancy with hemorrhage intra- or postuterine dilation and curettage.

AIM: This study aimed to examine the characteristics, management, and outcomes of delayed diagnosis of cesarean scar pregnancy (CSP) with hemorrhage intra- or postuterine curettage for early pregnancy termination. METHODS: The retrospective study, cases were identified from the interrogation of the hospital database and clinical data including the success rate of different treatments, vaginal bleeding time, abnormal beta-human chorionic gonadotropin (ß-hCG) time, and menstrual recovery time, preservation of uterus were analyzed. RESULTS: Medical records of 80 confirmed CSP cases with dilation and curettage (D&C) as primary treatment were analyzed; among them, 22 were treated with uterine arterial embolization (UAE) + methotrexate (MTX); 32 with UAE + surgery; 26 with only surgery or resection and repair. Treatment with UAE had less intraoperative blood loss (p < 0.05). UAE + surgery treatment had the highest success rate (96.8%, p < 0.05), the least vaginal bleeding duration after treatment (11.9 ± 9.6 days, p < 0.05), and least ß-hCG normalization time (17.4 ±  7.8 days, p < 0.05). CONCLUSION: UAE + surgery treatment is a favorable and effective option to control massive hemorrhage intra- or post-uterine curettage for early CSP termination.
