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.

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.
