Role of Interventional Radiology in Solid Organ Trauma

Abstract

This review describes the current role of diagnostic and interventional radiology in the management of solid organ trauma, particularly the role of non-operative endovascular interventions such as angioembolization (AE). We will also provide a brief highlight of interventions available for thoracic trauma. There has been a paradigm shift over the past 2 decades in the management of solid organ injuries from surgical management to non-operative management, especially in cases of minor injuries. Many factors, including the advances in multidetector contrast enhanced CT (MD-CECT) imaging, demands of cost-effective healthcare, and innovation of minimally invasive interventions with lower complication rates than surgical laparotomy have all contributed to this shift. Interventional radiology now plays a crucial role in the management of solid organ trauma, focusing on less invasive endovascular therapies. In addition, the grading and triaging of patients with stable solid organ traumatic injuries has become more reliant on MD-CECT findings. This review article highlights the common imaging findings, grading systems, and most current management guidelines for solid organ trauma with a brief highlight of thoracic trauma.
