TICI score
Also written as: TICI — Thrombolysis in Cerebral Infarction
Thrombolysis in Cerebral Infarction scale rating cerebral reperfusion success from 0 (no reperfusion) to 3 (complete reperfusion).
Full Definition
The Thrombolysis in Cerebral Infarction (TICI) score is a standardized angiographic grading system used to assess the degree of reperfusion achieved during endovascular stroke interventions. The scale ranges from 0 (no perfusion) to 3 (complete perfusion), with TICI 2b-3 considered successful recanalization. This scoring system is critical for evaluating procedural success and predicting patient outcomes in acute stroke interventions. The TICI score has largely replaced older classification systems and is now the standard endpoint in most stroke intervention trials.
Usage
Usage note: Always capitalize as TICI when used as acronym; use specific grade notation (e.g., TICI 2b, TICI 3).
In Context
- "The procedure achieved TICI 3 recanalization with complete restoration of flow to the middle cerebral artery territory." — Neurointerventional procedure report
- "Primary endpoint was defined as TICI 2b or greater reperfusion at 90 minutes post-procedure." — Clinical trial protocol
