PurposeThis study was designed to evaluate the clinical efficacy and safety of transcatheter arterial embolization (TAE) with n-butyl cyanoacrylate (NBCA) for intramuscular active hemorrhage of varied etiologies and anatomic sites.MethodsEighteen patients who demonstrated hematoma with pseudoaneurysm and/or active extravasation of contrast media underwent TAE with NBCA. Etiologies of hematoma included trauma, postoperative complication, and coagulopathy (due to underlying disease or anticoagulation therapy). Sites of embolization included chest wall, abdomen wall, retroperitoneum, and extremity. TAE was performed by using 1:3 to 1:5 mixtures of NBCA and iodized oil, either solely (n = 15) or in combination with microcoil (n = 3). The technical and clinical success rate, procedure-related complications, and clinical outcomes were evaluated.ResultsThe technical and clinical success rates were 100% and 83% (15/18), respectively. Two patients expired while admitted due to other comorbidities. One patient expired due to recurrent bleeding at another site. There were no serious complications relating to the embolization procedure.ConclusionsTAE with NBCA is effective and safe treatment modality for intramuscular active hemorrhage.
