下肢慢性动脉闭塞性疾病的外科血管旁路移植与腔内介入治疗

目的 按泛大西洋协作组织(Trans Atlantic Inter-Society consensus,TASC)分型对传统手术与腔内介入治疗的效果进行分析比较. 方法对2005年10月至2008年10月应用血管旁路移植术与腔内介入治疗下肢慢性动脉缺血患者201例的临床资料进行回顾性分析.其中男137例,女64例,男女之比为2.14:1.平均年龄(67±12)岁,其中>70岁患者共101例(占50.2%).结果 (1)腔内介入治疗术后6、12、24个月股浅动脉支架植入通畅率(100.0%、89.8%、75.0%)优于单纯扩张(82.4%、62.5%、35.7%),两者差异有统计学意义(P<0.05).(2)手术旁路移植术后24个月二期通畅率88.0%优于介入支架70.7%,两者差异有统计学意义(X2=6.232,P<0.05).结论 血管旁路移植适宜于TASC C、D型股浅动脉长段闭塞,腔内介入适宜于TASC A、B型股浅动脉短段闭塞,且支架植入优于单纯扩张;尽管腔内介入通畅率低于传统手术,但其具有的安全、快捷、可重复性高的特点,使其在下肢动脉闭塞症的治疗中占有重要地位.

A comparison for the patency rate between arterial bypass and interventional therapy of chronic lower limb ischemia

Objective To compare the long term outcome between traditional arterial bypass and interventional therapy for chronic lower limb ischemia according to the TASC classification. Method A retrospective study was undertaken on 201 cases receiving graft bypass or interventional therapy for CLI (chronic limb ischemia) from December 2005 to December 2008. Result The patency rate at 6 month. 12 month and 24 month after operation by femoral artery stent angioplasty in therapy group (100%, 89.8%, 75%) is higher than that of angioplasty group(82.4%, 62.5%, 35.7%), P <0.05. The 2nd term patency rate(88%) of operation group (24 months after operation) is higher than that of interventional group (70.7%), P<0.05. Conclusion Arterial bypass has higher long term patency rate and is applicable for femoral artery long segment obliterate classified as TASC C, D, while for the short segment femoral artery obliterate classified as TASC A, B interventional therapy especially stenting is an alternative despite of low patency rate.
