Traumatic Intraparenchymal Pseudoaneurysm on Initial Imaging Predicts Injury Progression in Patients with Nonoperative Major Blunt Liver Injury
Abstract Objective: Identify factors that would predict which patients would benefit from repeat imaging after major blunt liver injury. Summary of Background Data: Most patients who present with hemodynamic stability and no evidence of peritonitis after blunt liver injury are successfully managed nonoperatively. Little information is available regarding the utility of reimaging major blunt liver injuries for patients who are managed nonoperatively. Methods: A retrospective review of patients admitted to a level I trauma center with major blunt liver injuries (AAST grades 3 5) was conducted. Inclusion criteria were those admitted from July 2012 to June 2014 with blunt liver trauma who survived the first 24 hours and underwent repeat imaging. Data included demographics, procedures performed and computerized tomography (CT) scan findings. Findings on the second CT scan were categorized as Unchanged, Worse, Improved, or Negative. Results: 128 patients had blunt major liver injuries; 66 patients underwent rep.
