动脉切开取栓术治疗急性下肢动脉栓塞的临床分析

Clinical analysis of acute arterial embolism in lower extremity treated by arterial embolectomy

目的:探讨动脉切开取栓术治疗急性下肢动脉栓塞的疗效。方法:回顾性分析2005年8月至2010年8月应用下肢动脉切开取栓术治疗107例(113条肢体)急性下肢动脉栓塞患者的临床资料。结果:患者平均踝肱指数从术前的(0.39±0.20)提高至(0.89±0.22)(t=13.216,P<0.001)。保肢率89.4%(101/113),截肢率10.6%(12/113);病程≤48h接受取栓手术的95例患者中有7例截肢,病程>48h接受取栓手术的12例患者中有5例截肢,差异有统计学意义(χ2=9.381,P<0.001)。30d病死率4.7%(5/107)。结论:下肢动脉切开取栓术是治疗下肢动脉栓塞的一种有效的方法,早期诊断、早期手术取栓有利于提高保肢率和降低病死率。

Aim：To analyze the therapeutic effects of arterial embolectomy on acute arterial embolism in lower extremity.Methods：From August 2005 to August 2010,arterial embolectomy was performed in 107 cases of acute arterial embolism（113 lower extremities）.The clinical data were reviewed.Results：The average ankle-brachial index of the patients increased from（0.39±0.20） before operation to（0.89±0.22） after operation（t=13.216,P0.001）.The total limbs salvage rate was 89.4%（101/113）,and amputation rate was 10.6%（12/113）（χ2=9.381,P0.001）.The 30 day mortality rate was 4.7%（5/107）.Conclusion：Arterial embolectomy remains an effective treatment option for patients with acute arterial embolism of lower extremity.Early diagnosis and early embolectomy are conducive to improve limb salvage rate and to lower the mortality rate.
