BackgroundNonoperative management (NOM) has become the standard treatment of blunt hepatic injury (BHI) for stable patients. Contrast extravasation (CE) on computed tomography (CT) scan had been reported as a sign that is associated with NOM failure. The goal of this study was to further investigate the risk factors of NOM failure in patients with CE on CT scan.MethodsFrom January 2005 to September 2009, patients with CE noted on a CT scan as a result of BHI were studied retrospectively. Physiological parameters, severity of injury, amount of transfusion, type of contrast extravasation, as well as treatment outcome were compared between patients with NOM failure and NOM success.ResultsA total of 130 patients were enrolled. Injury severity scores, amount of blood transfusion before hemostatic procedure, and grade of liver injury were significantly higher in NOM failure than in NOM success patients. There was no statistical difference in the NOM success rate between patients with contrast leakage into the peritoneum and those with contrast confined in the hepatic parenchyma.ConclusionsHigher injury severity score, more blood transfusion, and higher grade of liver injury are factors that correlate with NOM failure in patients with BHI. Contrast leakage into the peritoneum is not always a definite sign of NOM failure in BHI. Early and aggressive angioembolization is an effective adjunct of NOM in BHI patients, even with contrast leakage into peritoneum.Copyright © 2012 Elsevier Inc. All rights reserved.
