目的：分析新的跨大西洋学会共识（TASC II）膝下分类与严重肢体缺血（CLI）患者肢体结局之间的关系。研究方法：对2006年至2013年接受244处膝下病变血管内治疗的166例连续CLI患者（平均年龄71岁; 113例男性）进行了一项单中心回顾性研究。比较了膝下病变的新TASC A/B与C/D分类的患者、手术、血管造影和肢体结局。在随访1、3、6和12个月时，通过多普勒超声确定收缩期峰值流速比>2.0，从而确定二元再狭窄。结果：72例（43.4%）患者有TASC A/B型病变，94例（56.6%）患者有TASC C/D型膝下病变。两组之间的基线人口统计学和组织损失（93% vs 94%，p=0.59）相似。TASC A/B病变较短（53 +/- 35 vs 170 +/- 83 mm，p
Purpose: To analyze the relationship between the new TransAtlantic Inter-Society Consensus (TASC II) infrapopliteal classification and limb outcomes among patients with critical limb ischemia (CLI). Methods: A single-center retrospective study was performed on 166 consecutive CLI patients (mean age 71 years; 113 men) undergoing endovascular treatment of 244 infrapopliteal lesions from 2006 to 2013. Patient, procedural, angiographic, and limb outcomes were compared for the new TASC A/B vs C/D classification for infrapopliteal lesions. Binary restenosis was determined by a peak systolic velocity ratio >2.0 by duplex ultrasound on follow-up at 1, 3, 6, and 12 months. Results: Seventy-two (43.4%) patients had TASC A/B lesions, while 94 (56.6%) had TASC C/D patterns of infrapopliteal disease. Baseline demographics and tissue loss (93% vs 94%, p=0.59) were similar between the groups. TASC A/B lesions were shorter (53 +/- 35 vs 170 +/- 83 mm, p
