1、糖尿病足潰瘍治療新概念足背動脈旁路手術對預防大截肢的作用,張耀中外科部 心血管中心 台中大甲李綜合醫院 台灣,2,背景,糖尿病增加週邊動脈疾病(PAD)的風險週邊動脈疾病是糖尿病足潰瘍患者截肢的重要危險因子有關糖尿病足潰瘍的處置在不同科別間，差異很大 整合、協調的處置對於患者的助益、生活品質及成本效益上相當重要,3,有關糖尿病足潰瘍的一些事實,糖尿病患者，終其一生發生足潰瘍的危險值估計約為15%(Palumbo P,et al.1985)糖尿病患者比非糖尿病患者有1540倍的截肢風險非外傷截肢糖尿病佔50%截肢會降低患者的身體機能及生活品質截肢部位(Reiber GE et al.1995)趾

3、儘速施行血管旁路手術續發步驟:清創、截趾、皮膚移植、皮瓣重建輔助步驟:高壓氧治療、局部生長因子、特殊敷料、照紅外線由哈佛大學 Dr LoGerfo 修訂,8,病人及方法,最近10年超過800例的遠端肢體旁路手術(遠端血管吻合處：足背動脈、脛後動脈、及側足底動脈)分析最早120位患者的136例手術，完成5年追蹤，並在此次大會上發表,9,10,F-U arteriogram:1 year later after OP(1999),11,12,13,手術適應症(N=136),14,手術適應症在最近的病例，超過90%的患者多係台灣其他醫學中心建議要膝上或膝下截肢的。,15,旁路手術的禁忘症,1.長期臥
