Combined Efficacy of Balloon Occlusion and Uterine Artery Embolization on Coagulation Function in Patients with High-Risk Placenta Previa during Cesarean Section

Abstract

Purpose. The present study was performed in order to investigate the conbined effect of balloon occlusion and uterine artery embolization on coagulation function in patients with high-risk placenta previa during cesarean section. Methods. There involved a total of 38 patients with high-risk placenta previa undergoing cesarean section in our hospital from August 2019 to January 2021. The patients enrolled were randomly divided into study group (19 cases, receiving balloon occlusion combined with uterine artery embolization) and control group (19 cases, receiving conventional cesarean section). The operation time, intraoperative blood loss, plasma injection volume and hospital stay of the two groups were recorded. Moreover, the postoperative coagulation function indexes, including thrombin time (TT), fibrinogen (FBI), activated partial thromboplastin time (APTT) and prothrombin time (PT), were monitored and compared. Neonatal Apgar score and postoperative complications of the two groups were regarded as parameters for comparison. Results. The intraoperative blood loss, plasma injection volume and hospital stay of the study group were significantly lower compared with the control group ( $P<0.05$ ), whereas the operation time of the two groups was comparable ( $P>0.05$ ). Compared with the control group, the levels of TT, APTT and PT were lower while the level of FBI was higher in the study group ( $P<0.05$ ). The Apgar 1-min and 5-min scores of newborns were compared between the two groups ( $P>0.05$ ). However, the incidence of postoperative complications in the study group showed evidently lower outcomes compared with the control group ( $P<0.05$ ). Conclusion. The combined approach of balloon occlusion and uterine artery embolization offered potential for improving the coagulation function of patients with high-risk placenta previa during cesarean section. In addition, the approach reduced the amount of blood loss and plasma injection, shortened the length of hospital stay, which was believed available for wide clinical application.
