Objective To investigate the clinical effect of endovascular stent-assisted angioplasty in the treatment of symptomatic stenosis or occlusion of the subclavian artery. Methods Clinical data of 17 patients with symptomatic stenosis or occlusion of the subclavian artery were analyzed retrospectively, who underwent endovascular stent-assisted angioplasty. Results Stent implantation was successful in 16 patients and failed in 1 with subclavian artery occlusion. The success rate was 94%. The subclavian artery steal phenomenon disappeared and clinical symptoms were improved significantly in the patients with successful surgery. No postoperative stent-related complications occurred. The patients were followed up for 6 to 12 months. The vascular ultrasound and CTA examination showed no in-stent restenosis. Conclusion Endovascular stent-assisted angioplasty is a safe and effective treatment method for symptomatic stenosis or occlusion of the subclavian artery.%目的：探讨血管内支架成形术治疗症状性锁骨下动脉狭窄或者闭塞病人的临床疗效。方法回顾性分析17例症状性锁骨下动脉狭窄或者闭塞病人的临床资料，采用血管内支架成形术治疗锁骨下动脉病变。结果16例病人成功植入支架，1例锁骨下动脉闭塞病人支架治疗失败，成功率94%。手术成功病人锁骨下动脉盗血征象消失，临床症状明显改善。术后无支架相关性手术并发症。随访6~12个月，血管超声及CTA检查未见支架内再狭窄。结论血管内支架成形术治疗症状性锁骨下动脉狭窄或者闭塞是安全、有效的治疗方法。
