Open heart surgery for posttraumatic inferior vena caval thrombosis.

A 40-year-old woman was diagnosed as intrahepatic hematoma after blunt abdominal trauma. One month later computed tomography (CT) revealed the inferior vena caval thrombus extending into the right atrium. Emergency thrombectomy was performed under cardiopulmonary bypass. We believe that the thrombus, which was derived from laceration of the hepatic vein, extended through the inferior vena cava into the right atrium, and was the eve of pulmonary embolization. CT study should be repeated, once the intrahepatic hematoma was recognized. We emphasize that we should recognize the existence of such complication to prevent the catastrophic result.
