A rare case of right proximal subclavian artery aneurysm: a case report

Aneurysms in the subclavian artery are rare. In this article, chest pain and dyspnea were reported as the first symptoms of a giant right subclavian artery true aneurysm. A 75-year-old female patient was admitted because of intermittent chest pain and dyspnea for 2 weeks. Computed tomography revealed a large gourd-shaped right proximal subclavian artery aneurysm (SAA). She had the signs of right chest pain which is identified as pre-rupture of aneurysm. Additionally, the patient was experiencing obvious symptoms of airway obstruction. A variable-diameter-covered stent was implanted through the right common carotid artery and brachiocephalic artery by an emergency surgery. After 26 months's follow-up, the patient was living well with no symptom of chest pain or dyspnea. A descending diameter covered stent implanted through right common carotid artery approach would be a proper method for the treatment of giant SAA.
