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 &gt;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\u00b135 vs 170\u00b183 mm, p&lt;0.001), less severely stenosed (77%\u00b124% vs 93%\u00b114%, p&lt;0.001), had a larger target vessel diameter (2.9\u00b10.5 vs 2.6\u00b10.5 mm, p&lt;0.001), and were less frequently chronic total occlusions (24% vs 64%, p&lt;0.001) compared with the TASC C\/D group. Three-year freedom from both amputation (85% vs 67%, p=0.02) and major adverse limb events (79% vs 61%, p=0.02) were significantly higher in the TASC A\/B group. Technical success rates (95% vs 80%, p&lt;0.001) and 1-year primary patency (58% vs 51%, p=0.04) were higher in the A\/B group. Overall 3-year survival was similar between the groups (96% A\/B vs 88% C\/D, p=0.2). Conclusion: TASC C\/D infrapopliteal lesions are associated with higher amputation and major adverse limb events rates and lower primary patency compared with TASC A\/B infrapopliteal lesions. Further studies are needed to assess the association between TASC C\/D infrapopliteal lesions and clinical outcomes in patients with CLI.<\/jats:p>","DOI":"10.1177\/1526602817704643","type":"journal-article","created":{"date-parts":[[2017,4,19]],"date-time":"2017-04-19T05:25:36Z","timestamp":1492579536000},"page":"321-330","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":35,"title":["Midterm Outcomes After Infrapopliteal Interventions in Patients With Critical Limb Ischemia Based on the TASC II Classification of Below-the-Knee Arteries"],"prefix":"10.1177","volume":"24","author":[{"given":"Gagan D.","family":"Singh","sequence":"first","affiliation":[{"name":"Division of Cardiovascular Medicine and Vascular Center, University of California Davis Medical Center, Sacramento, CA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ellen K.","family":"Brinza","sequence":"additional","affiliation":[{"name":"VA Eastern Colorado Healthcare System, Denver, CO, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Justin","family":"Hildebrand","sequence":"additional","affiliation":[{"name":"Division of Cardiovascular Medicine and Vascular Center, University of California Davis Medical Center, Sacramento, CA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stephen W.","family":"Waldo","sequence":"additional","affiliation":[{"name":"VA Eastern Colorado Healthcare System, Denver, CO, USA"},{"name":"Division of Cardiovascular Medicine, University of Colorado School of Medicine, Denver, CO, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"T.
