Massive hemoptysis caused by a ruptured subclavian artery aneurysm.

We report a case of left subclavian artery aneurysm, which ruptured and penetrated through the left upper lung parenchyma causing massive hemoptysis and a left hemothorax. Through sternothoracotomy, tangential aneurysmorrhaphy under proximal control and left upper pulmonary lobectomy were performed. The patient is doing well after nearly three years of follow-up.
