title: Budd-Chiari syndrome resulting from intrahepatic IVC compression secondary to blunt hepatic trauma.
abstract: Hepatic venous outflow obstruction (Budd-Chiari syndrome)is a rare sequel of abdominal trauma. Three cases of Budd-Chiari syndrome resulting from obstruction to the intrahepatic IVC by liver injury are reported. The CT findings include extrinsic compression of the intrahepatic inferior vena cava (IVC) by intraparenchymal and/or subcapsular hepatic haematoma, non-visualization or narrowing of one or more main hepatic veins with intravenous contrast-enhanced CT, and accumulation of low attenuation ascites. This entity should be distinguished from intraperitoneal bile leak or hemoperitoneum associated with major liver injury with which it could be confused. Decompression of the IVC and hepatic veins by surgical or percutaneous drainage of intrahepatic or subcapsular hematoma was curative in two of the three patients.
