Objectives

Narrative objectives1

For adult blunt liver injuries, the presence of contrast extravasation and/or pseudoaneurysm on contrast-enhanced CT at initial evaluation is considered an indication for transcatheter arterial embolization (TAE) (Japanese Guidelines for IVR in Hepatic Trauma 2016, recommendation grade C1). In particular, TAE is recommended for patients who are hemodynamically stable and do not show clinical signs of hemorrhagic shock (recommendation grade B). However, recent reports have suggested that even when extravasation or pseudoaneurysm is detected on initial contrast-enhanced CT, conservative management without angiography may achieve similar success rates in hemodynamically stable patients, and may even reduce complication rates associated with angiography and embolization. In Japan, based on the above-mentioned guidelines, angiography is frequently performed when extravasation or pseudoaneurysm is observed on contrast-enhanced CT, but we identified this issue as a research question to re-evaluate its potential benefits and harms.
