    PurposeTo assess the safety and efficacy of transcatheter arterial embolization (TAE) for the management of secondary postpartum hemorrhage (PPH) and to determine the factors associated with the clinical outcomes.Materials And MethodsA retrospective analysis of 52 patients (mean age, 31.6 y; range, 25-40 y) undergoing TAE for secondary PPH was performed. Clinical data, including maternal characteristics, delivery details, embolization details, and transfusion requirements, were obtained. Univariate analyses were performed to determine the factors related to clinical outcomes.ResultsThe major cause of bleeding was retained placental tissue (44.2%; 23 of 52). Actively bleeding foci were observed in 25 (48.1%) patients. Technical and clinical successes were achieved in 100% and 90.4% (47 of 52) of patients, respectively. Gelatin sponge particles with (n = 10) or without (n = 38) permanent embolic materials, such as microcoils or N-butyl cyanoacrylate, were most commonly used (92.3%; 48 of 52), whereas permanent embolic materials alone were used in 7.7% (4 of 52) of patients. In five patients, embolization failed, and these patients were managed by hysterectomy (n = 3), repeat TAE (n = 1), or conservative management (n = 1). Bleeding control was eventually achieved in all five patients. No maternal risk factors were related to clinical results. The median and mean follow-up periods were 3 months and 12.6 months (range, 1-62 mo). Regular menstruation resumed in all 44 patients with available follow-up, and 5 of the patients became pregnant.ConclusionsTAE for secondary PPH is safe and effective and showed technical and clinical success in 100% and 90.4% of patients, respectively. Approximately half of these patients showed a positive bleeding focus, and the use of permanent embolic materials was also common.Copyright © 2014 SIR. Published by Elsevier Inc.
