Staphylococcus aureus-associated infected subclavian artery pseudoaneurysm treated with dual bare-metal stent implantation: a case report

Year: 2026

Type: article

Abstract: Infected subclavian artery aneurysms are exceedingly rare, life-threatening vascular lesions associated with high risks of rupture and mortality. We report a 70-year-old male presenting with intermittent hemoptysis, who was diagnosed with a pseudoaneurysm of the left subclavian artery adjacent to the dominant vertebral artery. Blood cultures confirmed methicillin-sensitive Staphylococcus aureus infection. The patient underwent endovascular repair with dual bare-metal stents to preserve vertebral artery perfusion. Hemoptysis completely resolved post-intervention. Complete thrombosis and occlusion of the aneurysm sac were achieved at the 3-month follow-up, with remarkable sac shrinkage observed at 6 months. This case suggests that dual bare-metal stents may represent a feasible potential treatment alternative for highly selected patients with infected subclavian artery aneurysms. Long-term safety and efficacy remain to be further verified. Long-term antimicrobial therapy and close surveillance remain mandatory.
