摘　　要：目的探讨Silverhawk斑块旋切系统治疗下肢动脉硬化闭塞症的安全性及近期疗效。方法对术前超声及MRA检查诊断为下肢动脉硬化闭塞症的10例患者行Silverhawk斑块旋切治疗,术后行常规抗凝治疗,定期彩色多普勒超声复查随访。结果 10例患者下肢动脉均再通成功,技术成功率100%,术后即刻缺血症状改善明显,术后平均踝肱指数为0.87±0.06,高于术前的0.26±0.06(P<0.0001)。住院期间无并发症发生,随访3～15个月,中位随访时间9个月,患肢均保肢成功。结论使用Silverhawk斑块旋切系统治疗下肢动脉硬化闭塞症及支架内再狭窄、闭塞病变创伤小,安全性高,近期疗效显著。Objective To explore the security and short term efficacy of atherectomy using Silverhawk plaque excision system in treatment of arteriosclerosis obliterans in lower extremity.Methods Atherectomy with Silverhawk plaque excision system was performed in 10 patients with arteriosclerosis obliterans in lower extremity confirmed by ultrasound and MRA.Routine anticoagulation treatment was performed after the operation.Following up was carried out with color Doppler ultrasound.Results Revascularization was obtained in all patients.The technically successful rate was 100%.Iischemic symptoms relieved significantly immediately after the operation.The postoperative ankle/brachial index（ABI） was 0.87±0.06,which was higher than that of before operation（0.26±0.06,P0.0001）.No obvious complication occurred during the hospitalization.The follow-up range was 3—15 months（median=9 months）,limb salvage was successful.Conclusion Atherectomy with Silverhawk plaque excision system is minimal invasive,safe,having significant short-term efficacy for the treatment of arteriosclerosis obliterans in lower extremity,as well as for restenosis/reocclusion after stenting.
