Subclavian artery (SA) aneurysms (SCAA) are relatively uncommon but carry a significant risk of rupture, thrombosis and embolism if left untreated. We describe the etiology, mode of presentation and outcome of surgical management of 10 patients presenting with SCAA between January 1990 and December 2010. The mean age was 43.7 years. There were seven men and three women. Five patients had aneurysms due to trauma, four had it due to thoracic outlet syndrome and one had it secondary to atherosclerosis. Five patients presented with ischemic symptoms of the distal upper extremity, while the rest presented with a pulsatile neck mass. All patients were treated surgically. Six patients were approached with combined supra- and infraclavicular incisions. Aneurysm resection with reconstruction using saphenous vein or synthetic grafts was done in eight patients. There was no perioperative mortality. The early patency rate was 100%. Surgical treatment is effective and recommended for most patients with SCAA.
锁骨下动脉（SA）动脉瘤（SCAA）相对少见，但如果不治疗，破裂、血栓形成和栓塞风险很大。我们描述了1990年1月至2010年12月期间10例SCAA患者的病因、临床表现方式及手术治疗结果。平均年龄为43.7岁。男性7例，女性3例。5例患者因创伤导致动脉瘤，4例因胸廓出口综合征导致，1例继发于动脉粥样硬化。5例患者出现上肢远端缺血症状，其余患者表现为搏动性颈部肿块。所有患者均接受手术治疗。6例患者采用锁骨上和锁骨下联合切口。8例患者行动脉瘤切除并用大隐静脉或人工血管重建。围手术期无死亡病例。早期通畅率为100%。手术治疗有效，推荐用于大多数SCAA患者。
