SilverHawk斑块切除治疗动脉粥样硬化导致的下肢缺血14例报告

目的探讨SilverHawk斑块切除术的安全性和有效性。方法 2010年10月～2011年4月对14例动脉粥样硬化导致的下肢缺血施行SilverHawk斑块切除,支架后再闭塞或狭窄内膜切除9例,单纯下肢动脉斑块切除5例。采用同侧顺行股动脉穿刺6例,对侧股动脉逆行穿刺6例,左侧腋动脉穿刺1例,左侧腋动脉和左股动脉逆行穿刺1例。结果 14例手术均成功,出院时所有患者的再通血管保持通畅。7例间歇性跛行行走距离均增加到500 m以上,静息痛5例全部缓解,1例足趾溃疡面积由术前的3 cm×4 cm缩小为2 cm×2 cm,坏疽1例保持干燥出院。术后ABI 4例0.7～0.8,4例0.81～0.9,6例0.91以上。14例随访1～5个月,平均3.5月,1例间歇性跛行4个月后症状复发,1例坏疽因足部骨髓炎而膝下截肢,1例溃疡面愈合,静息痛无复发。结论 SilverHawk斑块切除技术是一种安全有效的方法,但疗效尚需要远期的随访结果验证。
