Emergency uterine artery embolization for the treatment of postcesarean massive hemorrhage caused by placenta previa / 实用放射学杂志

ABSTRACT

Objective To identify the arteriographic manifestations of emergency uterine artery angiography and the efficacy of embolization treatment of postcesarean massive hemorrhage caused by placenta previa.Methods Emergency uterine artery angiogra-phy was performed in 35 patients with massive hemorrhage after cesarean section due to placenta previa.Emergency uterine arterial embolization (EUAE)was conducted using embolic agents such as tricacryl gelatin microsphere (TAGM)and gelatin sponge.Arte-riographic manifestations and effect of the emolotherapy were analyzed retrospectively.Results Contrast extravasations were con-firmed in 27 patients,and uterine artery pseudoaneurysms were in 8.The hemorrhage completely stopped after embolotherapy in all patients.A 12 month follow-up showed no recurrence hemorrhage and any severe complications were observed in all patients,such as necrosis of the uterus and ovary.Conclusion EUAE can be used as a safe,effective and minimally invasive therapeutic option for postcesarean massive hemorrhage caused by placenta previa.It is the key for the success of embolotherapy to choice and use reasona-ble embolic agents.
