Efficacy and influence factors of uterine artery embolization in treatment of intractable postpartum hemorrhage / 实用放射学杂志

ABSTRACT

Objective To investigate the efficacy and influence factors of uterine artery embolization (UAE)in treatment of intractable postpartum hemorrhage (PPH).Methods 126 patients with intractable PPH were treated by UAE in our hospital.We analyzed the influence factors of failed UAE treatments according to the amount of bleeding,the stability of hemodynamics,with disseminated intravascular coagulation(DIC)or not and active extravasation detected in angiography.Results In 126 intractable PPH patients,13 cases (10.3%) failed to stop bleeding after UAE and the other 113 cases (89.7%)successfully got hemostasis.Logistic regression analysis showed that DIC was a significant factor in failed UAE group (P=0.033,OR 0.107,95%CI 0.014-0.835).Conclusion UAE is an effective method of treating intractable PPH.DIC may be the main cause of the failure of UAE in treatment of intractable PPH.
