# A Rare Penetrating Injury to an Aberrant Right Subclavian Artery and the Turbulent Course of Endovascular Repair

## TL;DR

A rare case of a gunshot wound causing injury to an unusual blood vessel in the neck is described, along with the complex treatment process.

## Contribution

This paper presents a rare clinical case involving a penetrating injury to an aberrant right subclavian artery and its endovascular repair challenges.

## Key findings

- A 27-year-old male sustained a gunshot wound causing injury to the esophagus and an aberrant right subclavian artery.
- Endovascular repair of the pseudoaneurysm was complicated by multiple events related and unrelated to stents.
- The case highlights the unique challenges in managing vascular trauma involving an aberrant artery.

## Abstract

Penetrating neck trauma carries high morbidity and mortality due to the involvement of major vascular structures and anatomical complexity. A penetrating injury to an aberrant right subclavian artery (ARSA) is very rare and presents unique management challenges. This case details a 27-year-old male patient with a gunshot wound which resulted in esophageal injury and ARSA pseudoaneurysm. Following endovascular repair of the ARSA pseudoaneurysm, the clinical course was complicated by several events, some related to the stents and others unrelated to them.
