TICI
Also written as: TICI — Thrombolysis in Cerebral Infarction
Thrombolysis in Cerebral Infarction scale, used to grade arterial recanalization success following endovascular stroke treatment.
Full Definition
The Thrombolysis in Cerebral Infarction (TICI) scale is a standardized grading system used to assess the degree of arterial recanalization achieved during endovascular stroke treatment. The scale ranges from 0 (no recanalization) to 3 (complete recanalization), with TICI 2b representing near-complete recanalization with filling of ≥50% of the downstream territory. TICI 2b-3 recanalization is considered successful reperfusion and is associated with improved clinical outcomes. This grading system is essential for procedural documentation, quality metrics, and research standardization in endovascular stroke care.
Usage
Usage note: Always specify numerical grade (e.g., TICI 2b) for precise communication of recanalization success.
