Further, podiatry experts and experts of evidence-based medicine were included.  \nEndovascular Today: What are the most significant differences between the recommendations presented in TASC 2000 and those in TASC II 2007? Which lesion types were affected most, and why?  \nDr. Norgren: In principle, diabetes and its vascular complications were more extensively discussed in TASCII. There is great focus on prevention. In addition, concerning treatment, the TASC classification of lesions has been kept as such, but modified to reflect increased evidence for endovascular treatment of more extensive lesions.  \nEndovascular Today: When developing the recommendations, what factors were considered?  \nDr. Norgren: At this occasion, the level of evidence was considered to grade recommendations. Those levels have been graded “A” when randomized controlled trials are available,“B” when other well-performed studies exist, and “C” for other evidence, such as consensus or expert statements.  \n“   the TASC classification of lesions has been kept as such, but modified to reflect increased evidence for endovascular treatment of more extensive lesions.”  \nEndovascular Today: What developments led to the new recommendations?  \nDr. Norgren: Little has been shown regarding the treatment of peripheral arterial disease, especially critical limb ischemia, while there is a technical development that justifies more endovascular treatment than was the case with the original TASC guidelines. Great emphasis has been put on diabetes, which has clearly increased as a risk factor and is now at the same level as smoking. Clear recommendations have now been given to perform ankle-brachial indices in some categories of subjects, such as all patients older than 70 years, with or without risk factors.  \nEndovascular Today: What do these changes indicate regarding the trends we are seeing in modern vascular care?  \nJUNE 2007 I ENDOVASCULAR TODAY I 53  \n COVER STORY  \n\n|  |  |\n| --- | --- |\n| PREFERRED OPTIONS FOR TREATING FEMOROPOPLITEAL LESIONS |  |\n| TASC 2000 |  |\n| | TASC TYPE A\u003Cbr>• Single stenosis \u003C3 cm in length, not at the origin of the superficial femoral artery (SFA) or the distal popliteal artery\u003Cbr>Endovascular therapy is the treatment of choice.\u003Cbr>TASC TYPE B\u003Cbr>• Single stenoses or occlusions 3 cm to 5 cm long not involving the distal popliteal artery\u003Cbr>• Heavily calcified stenoses up to 3 cm in length\u003Cbr>• Multiple stenoses or occlusions, each \u003C3 cm\u003Cbr>• Single or multiple lesions in the absence of continuous tibial runoff to improve inflow for distal surgical bypass\u003Cbr>Endovascular therapy is more often used, but there is insufficient evidence to make a firm recommendation.\u003Cbr>TASC TYPE C\u003Cbr>• Single stenoses or occlusions longer than 5 cm\u003Cbr>• Multiple stenoses or occlusions, each 3 cm to 5 cm, with or without heavy calcification\u003Cbr>Surgical treatment is more often used, but there is insufficient evidence to make a firm recommendation. |\n| | TASC TYPE D\u003Cbr>• Complete common femoral artery or SFA occlusions, or complete popliteal artery and proximal trifurcation vessels occlusion\u003Cbr>Surgery is the treatment","cbCaiuM9vsJ09FUB","https://ap.wps.com/l/cbCaiuM9vsJ09FUB","pdf",366628,"English","# COVER STORY\n## TASC II 2007: What Has Changed?\n## Committee Formation and Membership\n## Key Differences Between TASC 2000 and TASC II 2007\n## Evidence Grading for Recommendations\n## Developments Leading to the New Recommendations\n## Trends in Modern Vascular Care\n## Preferred Options for Treating Femoropopliteal Lesions","[{\"question\":\"How did the committee membership change from TASC 2000 to TASC II 2007?\",\"answer\":\"TASC II expanded working group membership from 14 to 16 societies and broadened representation beyond North America and Europe to include Japan, Australia, and South Africa.
