摘要
目的：探讨术前准确确定因下肢动脉缺血需行截肢的平面的方法。方法：回顾性研究澳大利亚Ａｕｓｔｉｎ医学中心２０２例病人的２３２条下肢截肢的ＤＳＡ资料，建立一个“分数”标准，对下肢远端流出道动脉进行评分，以确定合适的截肢平面。结果：膝上截肢者分数＜１２分，截肢６５条；膝下截肢者分数为１２～１９分，截肢７４条；半足截肢２０～２５分，截肢６６条；截趾＞２５分，截趾２７趾。结论：用此标准可在术前较准确地预测截肢平面。鉴于该标准是建立于回顾性研究基础之上，尚需进行前瞻性研究。
Objective: To explore a appropriate method to determine precisely the amputation level in patients with ischemic lower limb(s). Methods: A“scoring system”for distal runoff blood vessel patency as shown by preoperative angiogram was used to determine the appropriate amputation level. The records of 202 patients undergoing 232 ischemic lower extremity amputation at Austin Medical Center, Australia from Jan 1996 through Dec 2000 were analysed retrospectively. Results: The lower the score, the higher the level of amputation(P<0.005). In patients with a score less than 12, an above knee amputation above knee should be applied; for a score of 12～19, a below knee amputation; for a score of 20～25, a forefoot amputation would be sufficient and for a score of over 25, a toe amputation would be all that was required. Conclusions: The scoring system by means of preoperative angiogram is a direct and practical method to assess the runoff blood vessel status and predict the level of amputation in an ischemic lower limbs.
