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 ,P < 0. 001 ). The total limbs salvage rate was 89. 4%( 101/113 ),and amputation rate was 10. 6%( 12/113 )(x2 = 9. 381 ,P <0. 001 ). The 30 day mortality rate was 4.7%( 5/107 ). Conclusion:Arterial embolectomy remains an effective treatment option for patients with a-cute arterial embolism of lower extremity. Early diagnosis and early embolectomy are conducive to improve limb salvage rate and to lower the mortality rate.%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≤48 h接受取栓手术的95例患者中有7例截肢,病程>48 h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).30 d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.
