Johannes Lammer, Vienna, Austria, told CX 33 delegates that an “endovascular first” strategy for all TASC lesions was recommended in the proposed update to the TASC II guidelines.,大連醫(yī)科大學附屬一院,2008年1月-2010年2月 143例 失訪：30例 死亡：5例 二次手術：39例 截肢：6例,腔內治療的2年保肢率：94.2%；一期通暢率：59.8%。,期待更多中心聯(lián)合的結果！,TASC C&D Lesions for SFA,腔內治療的方法 內膜下成型術：a.順行 b.逆行 c.順+逆行 器械輔助內膜下成型術：a.導絲穿刺 b.球囊輔助 c.
