Subclavian artery aneurysm is an extremely rare condition with potentially life-threatening complications, including rupture and embolization. This condition is generally the result of atherosclerosis, medial degeneration, trauma, or infection. We report the case of an 83-year-old man who developed hemoptysis due to the rupture of a saccular aneurysm at the origin of the left subclavian artery. This case highlights the importance of early recognition and emergency management of subclavian artery aneurysms, which, despite their rarity, carry significant morbidity and mortality risks.
