BACKGROUND AND PURPOSE: Modified Thrombolysis in Cerebral Infarction (mTICI)2b/3 has been considered the criterion for successful reperfusion in endovascular treatment. This study aimed to compare the therapeutic safety and efficacy of mTICI2b and mTICI3 recanalization, and to analyze the factors related to outcomes in everyday clinical practice.
MATERIALS AND METHODS: This is a single-center retrospective analysis of 224 patients who underwent successful thrombectomy (achieving a mTICI score ≥2b). The primary outcomes included a modified Rankin score (mRS) of 0-2 at 90-day, mortality, and symptomatic intracranial hemorrhage.
RESULTS: A total of 111 patients achieved mTICI2b status (49.6%), and 113 achieved mTICI3 status (50.4%). The comparison between mTICI2b and 3 reperfusions showed no differences in short-term outcomes, 90-day mRS, complications, and mortality. There was a trend toward more passes in mTICI2b patients, although the difference was not significant. The univariate analysis showed that poor outcomes after endovascular treatment were associated with older age, previous history of coronary heart disease, atrial fibrillation, diabetes, tandem occlusions, high National Institutes of Health Stroke Scale (NIHSS) score on admission, and general anesthesia. A previous history of coronary heart disease, a high NIHSS score on admission, and the use of general anesthesia were independent factors that affected the therapeutic effects.
CONCLUSION: The superiority (efficacy and safety) of mTICI3 reperfusion was not significant compared with that of mTICI2b reperfusion. Prolonged efforts to achieve mTICI3 after achieving mTICI2b should be considered prudently for those with difficulty achieving 100% reperfusion.
