Post-Traumatic False Aneurysm of the Left Subclavian Artery in a 17-Year-Old: A Rare Case Report

We report the case of a 17-year-old male who presented with a left supraclavicular mass, seven months after sustaining a stab wound to the base of the neck. Doppler ultrasound and computed tomography angiography (CTA) revealed a pseudoaneurysm of the proximal segment of the left subclavian artery. Endovascular repair using a 6 mm × 50 mm covered stent was performed successfully. The postoperative course was uneventful, with complete exclusion of the pseudoaneurysm and preserved patency of the arterial lumen. This case highlights the importance of suspecting vascular injury in cases of penetrating trauma and discusses the increasing role of endovascular therapy in managing subclavian artery lesions.
