Effect of Uterine Artery Ligation and Uterine Artery Embolization on Postpartum Hemorrhage Due to Uterine Asthenia after Cesarean Section and Its Effect on Blood Flow and Function of Uterine and Ovarian Arteries

Objective. To investigate the efficacy of uterine artery ligation (UAL) and uterine artery embolization (UAE) in the treatment of uterine asthenia postpartum hemorrhage (PPH) after cesarean section and its effect on uterine and ovarian artery blood flow and function. Methods. 100 patients with uterine asthenia PPH after cesarean section in our hospital from January 2018 to November 2020 were randomly divided into 50 cases in the UAL group and 50 cases in the UAE group. They were followed up for 12 months. The bleeding volume, operation time, immediate hemostasis rate, and hemostasis effective rate; lochia clearance time and menstrual rehydration time; RI and S/D; and serum FSH, E2, and LH levels were compared between the two groups. Results. Compared with the UAL group, the amount of bleeding in the UAE group was significantly increased and the operation time was significantly shortened ( $p<0.05$ ). There was no significant difference in the immediate hemostatic rate and hemostatic effective rate between the two groups ( $p>0.05$ ). There was no significant difference in lochia clearance time and menstrual rehydration time between the two groups ( $p>0.05$ ). There was no significant difference in RI and S/D between the two groups ( $p>0.05$ ). Compared with before the operation, the levels of FSH and LH in the two groups decreased significantly, and the level of E2 increased significantly ( $p<0.05$ ). There was no significant difference between the two groups ( $p>0.05$ ). Conclusion. The efficacy of UAL and UAE in the treatment of PPH with uterine asthenia after cesarean section and its effect on the blood flow and function of uterine and ovarian arteries are equivalent, but the amount of bleeding in UAL is less and the operation time of UAE is shorter. The appropriate operation method can be selected according to the actual situation.
