The role of internal iliac artery intraoperative vascular clamp temporary occlusion in abnormally invasive placenta.

ABSTRACT

OBJECTIVE: To investigate the efficacy of internal iliac artery intraoperative vascular clamp temporary occlusion in the treatment of abnormally invasive placenta. METHOD: This retrospective study enrolled 153 patients diagnosed with abnormally invasive placenta between January 2018 and December 2021. The patients were divided into a study group (n = 88, undergoing cesarean section followed by internal iliac artery vascular clamp temporary occlusion) and a control group (n = 65, receiving routine cesarean section). The general situation, intraoperative conditions, postoperative complications, and neonatal outcomes were compared between the two groups. RESULTS: The hysterectomy rate in the study group was significantly lower than that in the control group. However, there were no significant differences in intraoperative blood loss, blood transfusion, postoperative intensive care unit transfer rate, or neonatal outcome between the groups. Further subgrouping showed that in patients with placenta increta, the hysterectomy rate and intraoperative bleeding amount were significantly lower in the occlusion group. Nevertheless, these advantages were not significantly different between the groups in patients with placenta percreta. CONCLUSION: Vascular clamp temporary occlusion of internal iliac artery is an effective method for controlling hemorrhage and decreasing the incidence of hysterectomy in patients with placenta increta. For patients with placenta percreta, the benefit is limited.
