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.
