TASC classification of the aortic and iliac lesions [permission to reproduce the image obtained from Elsevier through Rightslink license 3877131206925 dated 27 May 2016].

Type A lesions	(i) Single stenosis ≤ 10 cm in length; (ii) Single occlusion ≤ 5 cm in length
Type B lesions	(i) Multiple lesions (stenoses or occlusions), each ≤5 cm; (ii) Single stenosis or occlusion ≤ 15 cm not involving the infrageniculate popliteal artery; (iii) Single or multiple lesions in the absence of continuous tibial vessels to improve inflow for a distal bypass; (iv) Heavily calcified occlusion ≤ 5 cm in length; (v) Single popliteal stenosis
Type C lesions	(i) Multiple stenoses or occlusions totaling > 15 cm with or without heavy calcification; (ii) Recurrent stenoses or occlusions that need treatment after two endovascular interventions
Type D lesions	(i) Chronic total occlusions of CFA or SFA (>20 cm, involving the popliteal artery); (ii) Chronic total occlusion of popliteal artery and proximal trifurcation vessels

CFA: common femoral artery; SFA: superficial femoral artery. Adapted from the TASC II Consensus Document. Eur J Vasc Endovasc Surg 2007, 33:S1–S70.
