Intrathoracic segment of the subclavian artery is an unusual location for peripheral arterial aneurysms. They are normally caused by atherosclerosis, medial degeneration, trauma, and infection. We report a case of a patient with right subclavian artery aneurysm presenting with hoarseness. Chest radiograph demonstrated a superior mediastinal mass. Laryngoscopy showed a fixed right vocal cord. By chest computed tomography, magnetic resonance imaging, and angiography, preoperative diagnosis was established as a saccular aneurysm with afferent loop and efferent loop. Patient underwent complete resection of the aneurysm followed by endto-end anastomosis via median sternotomy. Postoperative pathology was consistent with an atherosclerotic aneurysm filled with thrombus. After surgical operation, hoarseness is still continued.
锁骨下动脉的胸段是周围动脉动脉瘤的不寻常位置。它们通常由动脉粥样硬化、中膜退变、创伤和感染引起。我们报告一例右锁骨下动脉瘤患者出现声音嘶哑。胸部X线片显示上纵隔肿块。喉镜检查显示右侧声带固定。通过胸部计算机断层扫描、磁共振成像和血管造影，术前诊断为带有输入环和输出环的囊状动脉瘤。患者通过正中胸骨切开术接受了动脉瘤的完全切除，随后进行了端端吻合。术后病理与充满血栓的动脉粥样硬化性动脉瘤一致。手术后，声音嘶哑仍持续存在。
