    Abstract:
    BACKGROUND: Although transarterial embolization (TAE) can powerfully control postpartum hemorrhage (PPH), clinical failure of TAE is not uncommon. PURPOSE: To discover whether any parameters could predict timely clinical failure of TAE, then whether a supplementary intervention could be promptly initiated. MATERIAL AND METHODS: We retrospectively analyzed 118 TAE procedures in 113 patients with PPH performed at our institution between January 2012 and May 2015. The patients were divided into the following groups: clinically successful TAE and failed TAE. Successful TAE was defined as obviation of supplementary embolization or surgical intervention for hemostasis. Gestational conditions, angiographic factors, maternal vital signs, and laboratory data were compared between the two groups. RESULTS: In total, 100 (84.8%) TAEs were clinically successful. Multivariate logistic regression analyses revealed independent risk factors of TAE clinical failure, including the requirement for augmented embolic agents, placental retention, and international normalized ratio > 1.3 ( P = 0.009, 0.001, and 0.005, respectively). The post-TAE shock index was significantly associated with TAE failure, using a cut-off value of 0.8. CONCLUSION: The discovered independent risk factors of TAE clinical failure existed before or during the TAE procedure and could not reflect the post-TAE conditions. Although the post-TAE shock index was not an independent factor, it reflected the conditions after TAE and could indicate TAE clinical failure timely.
