All patients diagnosed with liver injury, either through arteriogram films or computed tomography, will be identified through a search of our radiology information system.  Films will be reviewed for the size of laceration and grade of liver injury.  This will be correlated to the indication for emergency surgical intervention or interventional radiology intervention.  The type of radiologic interventions will be categorized and the outcomes assessed through chart review.  The raw data will be retained without identifiers following the chart review and statistics will be generated for the different types of liver injuries and the incidents and impact of surgical and radiologic intervention.
