초록

Purpose: Hepatic pseudoaneurysm (HPA) is a rare but potentially life-threatening sequela of liver trauma. This study aimed to evaluate the number of children diagnosed with HPAs following blunt and penetrating liver trauma at a major trauma center in London over a 5-year period. Methods: A retrospective analysis was conducted of patients aged <18 years with liver injuries admitted to our institution between 2017 and 2022. Patients were identified through the local trauma registry. Data collected included patient demographics, imaging details (including ultrasound scanning and computed tomography [CT]), liver injury grade, and management plans. Results: Thirty-four patients were identified (mean age, 12 years; range, 1-17 years). There were 26 men (76.5%) and 8 women (23.5%). Twenty-three patients (67.6%) sustained blunt injuries, and 11 (32.4%) sustained penetrating liver injuries. Among 30 patients (excluding 4 patients who died), 18 (60.0%) underwent repeat CT imaging. CT imaging identified four HPAs (13.3%), two of which were treated with embolization. Of the 12 patients who did not undergo repeat CT, 6 (50.0%) had follow-up ultrasound scanning. Conclusions: Hepatic pseudoaneurysms following trauma are uncommon. Their management in the pediatric population presents challenges regarding follow-up imaging, particularly the use of CT. Although the absence of standardized protocols complicates surveillance strategies, an individualized approach informed by patient-specific factors is essential. Contrast-enhanced ultrasound may optimize HPA detection while minimizing radiation exposure.
