目的:评价SilverHawk斑块切除术治疗下肢动脉硬化闭塞症的临床疗效及安全性。方法:应用SilverHawk斑块切除系统治疗42例下肢动脉硬化闭塞症患者,共44条肢体。术后采用CTA或彩超对管腔通畅情况进行评估随访。结果:43条肢体经腔内开通成功,1例因术中动脉破裂置入覆膜支架,技术成功率(97.7%)。1例术后行小腿截肢术。随访1～6个月,动脉管腔通畅。结论:SilverHawk斑块切除技术是治疗下肢动脉硬化闭塞症的一种安全有效的新方法,近期效果满意。

Objective To evaluate the clinical effieaey and security of plaque excision witil SilverHawk in treating arteriosclerosis obliterans of lower extremity. Methods 44 lower extremities in 42 patients with arterioselerosis oblilerans of lower extremity were treated with SilverHawk directional alhereetomy. Pateney was evalualed by color duplex sonography or CTA besides clinical examinalion during follow-up. Results 43 lower exlremities were reeanalizaled successfully via intraluminal approach. The technical sueeess rate was 97.7% with I ease of interventional failure, and 1 case with leg amputation clue to the lower limb gangrene. After 1-6 months of follow-tap, the pateney rate was 100%. Conclusion SilverHawk dreetional athereetomy was a safe and effective way for treating lower arteriosclerosis obliteran.
