Tasc

TASC is an acronym for "TransAtlantic Inter-Society Consensus" group. In 2000, this group presented a consensus document of vascular specialists based on sound data on epidemiology, diagnostics and therapy of PAVK. The classification of lesions was based on their localization (aorto-iliac, femoropoliteal, infrapopliteal), the extent of the lesions (stenosis, occlusion, single vs. multiple lesions) and the extent of the lesions (in centimeters).

Each vascular segment is assigned lesion types from A to D: Type A lesions are to be treated interventionally radiologically, type B lesions primarily interventionally, type C lesions without high surgical risk mainly vascular surgery and type D lesions vascular surgery.

The assessment of lesions in the course of the vessel refers only to one localization.
