Efficacy of Transcatheter Arterial Embolization for Hemorrhage Control in Traumatic Hepatic Injury With Celiac Axis Stenosis

TL;DR

This study shows that transcatheter arterial embolization is a safe and effective treatment for controlling bleeding in liver injuries complicated by celiac axis stenosis.

Contribution

The study demonstrates the efficacy of TAE in traumatic liver injury patients with celiac axis stenosis, a rare and complex condition.

Findings

All nine patients achieved technical success with TAE.

A clinical success rate of 77% was observed with no 30-day mortality.

Medial arcuate ligament compression was identified as a common cause of celiac axis stenosis.

Abstract

Purpose: This study aimed to evaluate the safety and efficacy of transcatheter arterial embolization (TAE) for hemorrhage control in patients with traumatic liver injury complicated by celiac axis stenosis (CAS).

Methods: Nine patients diagnosed with CAS who underwent TAE between January 2012 and December 2024 were included in this retrospective study. Imaging studies were used to assess the vascular anatomy, and clinical outcomes were analyzed, focusing on technical and clinical success rates and complications.

Results: All patients achieved technical success with TAE, with a clinical success rate of 77%, and no 30-day mortality. Seven patients had medial arcuate ligament compression, which was identified as the cause of CAS, while two patients had atherosclerosis.

Conclusion: TAE is a safe and effective intervention for managing hemorrhage in traumatic liver injury complicated by CAS. Thorough assessment of computed tomography images is crucial for diagnosing the underlying causes of CAS and optimizing catheterization strategies.
