A Clinical Case of Right Subclavian Artery Aneurysm

Abstract

A 61-year-old male rectal cancer patient receiving chemotherapy experienced hoarseness. Chest CT revealed a right subclavian artery aneurysm 33 mm in diameter protruding into the pleural cavity. Our surgical approach was via a right collar incision and median sternotomy. The aneurysm was resected after clamping the right carotid, right subclavian, and brachiocephalic arteries. The right subclavian artery was reconstructed with a primary end-to-end anastomosis. The important issues in subclavian aneurysm repair are the method of surgical approach and the maintenance of cerebral blood flow. Therefore, careful preoperative assessment should be undertaken for each case.
