Temporary Internal Iliac Artery Blockage versus Uterine Artery Embolization in Patients After Laparoscopic Pregnancy Tissue Removal Due to Cesarean Scar Pregnancy.

Objective: This study aims to evaluate the clinical value of laparoscopic temporary internal iliac artery blockage (TIIAB) compared with uterine artery embolization (UAE) in type III cesarean scar pregnancy (CSP).

Methods: A total of 76 patients with type III CSP admitted to the Department of Gynecology the First Affiliated Hospital of Zhengzhou University between September 2017 and June 2019 were selected for this retrospective study. Thirty-six of them in the study group received TIIAB, and the rest in control group received UAE. Laparoscopic pregnancy tissue was removed from all patients, and the uterine defects were repaired. The absence of remnants was then confirmed using ultrasonography. Follow-ups were performed in the two groups for six months, and the factors of intraoperative blood loss, operation and menelipsis time, 24-h human chorionic gonadotropin decline rate, postoperative complications, hospitalization days, hospitalization costs, peri-operative hormone levels, and ovarian function indicators were compared between the two groups and within each group.

Results: There were statistically significant differences in the hospitalization cost, menelipsis time, and postoperative complication incidence between the two groups (p < 0.05). There were statistically significant differences between ovarian function at one month and three months after surgery (p < 0.05) as well as among the follicle-stimulating hormone, luteinizing hormone, and estradiol levels at one, three, and six months after surgery in the control group (p < 0.05).

Conclusion: Compared with uterine artery embolization, laparoscopic TIIAB has the advantages of a low hospitalization cost, lower postoperative complication rate, and shorter menelipsis time. Moreover, it avoids ovarian function damage. It is a safe method worthy of clinical popularization.
