Patients (4) with blunt abdominal trauma did not have surgical treatment for intrahepatic hemorrhage and hematoma. Two patients were diagnosed 24 h after injury as having significant active hemorrhage and were treated by superselective transcatheter occlusion of the hepatic artery. Two patients were diagnosed 1 wk after injury as having quiescent intrahepatic hematoma and recovered without complication. Nonoperative management of selected patients with an intrahepatic hematoma is reasonable and safe. Patients should be observed periodically with radioisotope scans, ultrasound or computerized tomography until the hematoma resolves.
