Pronunciation: task
Also written as: TASC — Trans-Atlantic Inter-Society Consensus
Classification system for peripheral arterial disease lesions that guides treatment recommendations based on anatomy and complexity.
Full Definition
TASC (Trans-Atlantic Inter-Society Consensus) is a standardized classification system used to categorize peripheral arterial disease lesions according to their anatomical characteristics and complexity. The system divides lesions into four categories (A through D) based on factors such as lesion length, location, and morphology. TASC A lesions are simple and typically treated with endovascular methods, while TASC D lesions are complex and usually require surgical bypass. This classification helps clinicians make evidence-based treatment decisions and standardizes reporting in vascular medicine literature.
