TASC classification
Pronunciation: task
Also written as: TASC — Trans-Atlantic Inter-Society Consensus
Standardized system for categorizing peripheral arterial disease lesion complexity to guide treatment selection between endovascular and surgical approaches.
Full Definition
The Trans-Atlantic Inter-Society Consensus (TASC) classification is a widely accepted system for categorizing peripheral arterial disease lesions based on anatomical complexity, length, and location. The classification grades lesions from A to D, with Type A lesions being simple and suitable for endovascular treatment, while Type D lesions are complex and typically require surgical bypass. This standardized approach helps clinicians select appropriate treatment strategies, compare outcomes across studies, and communicate lesion complexity effectively among multidisciplinary teams.
Usage
Usage note: Specify anatomical location (aortoiliac vs femoropopliteal) when using TASC classification.
In Context
- "The TASC B lesion in the superficial femoral artery was successfully treated with balloon angioplasty." — Interventional procedure report
- "Given the TASC D classification, surgical bypass was recommended over endovascular intervention." — Treatment planning discussion
