TASC classification
Also written as: TASC — Trans-Atlantic Inter-Society Consensus
A standardized system for categorizing peripheral arterial disease lesions by complexity and morphology to guide treatment decisions.
Full Definition
The Trans-Atlantic Inter-Society Consensus (TASC) classification system categorizes arterial lesions into four types (A through D) based on length, location, and complexity. TASC A and B lesions are typically suitable for endovascular treatment, while TASC C and D lesions may require surgical intervention. This classification helps standardize treatment approaches and enables comparison of outcomes across different studies and institutions.
Usage
Usage note: Always specify whether referring to original TASC or updated TASC II classification system.
In Context
- "The patient presented with a TASC D lesion requiring surgical bypass rather than endovascular intervention." — Clinical documentation
