# Successful Hybrid Endovascular and Open Approach for Exclusion of a Left Subclavian Artery Aneurysm

## TL;DR

A 78-year-old man successfully underwent a hybrid surgical approach to treat a rare left subclavian artery aneurysm.

## Contribution

A novel hybrid endovascular and open surgical technique is presented for treating subclavian artery aneurysms.

## Key findings

- The aneurysm was successfully excluded using a stent graft and direct ligation.
- Postoperative imaging confirmed complete exclusion of the aneurysm.
- The hybrid approach avoided the need for invasive open surgery.

## Abstract

Subclavian artery aneurysms are rare and challenging to treat owing to their anatomical location and proximity to critical branches, including the vertebral artery. We report the case of a 78-year-old man with a left subclavian artery aneurysm. The aneurysm was located in the mediastinum and measured 31 mm in diameter. The proximal side of the aneurysm was sealed with a stent graft, while the distal side was accessed through a supraclavicular incision and directly ligated. Postoperative imaging confirmed complete exclusion. This hybrid approach avoided invasive open surgery and provided a favorable outcome.
