Abstract:
ObjectiveTo investigate the difference in the outcomes in patients with acute anterior circulation stroke having achieved the Thrombolysis in Cerebral Infarction (TICI) 2b and TICI 3 recanalization after mechanical thrombectomy.MethodsThe patients with acute anterior circulation stroke having achieved successful recanalization after mechanical thrombectomy were enrolled retrospectively.They were divided into TICI 2b (almost complete recanalization) group and TICI 3 (complete recanalization) group.The good outcome was defined as the modified Rankin Scale score 0-2 at 3 months after onset.ResultsA total of 83 patients were enrolled in the study, including 38 patients (45.8%) with TICI 2b and 45 (54.2%) with TICI 3;49 (59.0%) had good outcome, and 34 (40.9%) had poor outcome.The good outcome rate in the TICI 3 group was significantly higher than that in the TICI 2b group (68.9% vs.47.4%;χ2=3.946, P=0.047).After adjusting for age, hypertension, diabetes, baseline systolic blood pressure, triglyceride, intravenous thrombolysis, and ASITN/SIR collateral grades, TICI 3 was an independent predictor for good outcome at 3 months after onset (odds ratio [OR] 3.759, 95% confidence interval [CI] 1.098-12.871;P=0.035), while the higher baseline National Institutes of Health Stroke Scale score (OR 0.820, 95% CI 0.715-0.941;P=0.005) and higher fasting glucose (OR 0.610, 95% CI 0.410-0.906;P=0.014) were the independent predictors for poor outcome at 3 months after onset.ConclusionsThere are difference in the outcomes in patients with successful recanalization in anterior circulation stroke treated with mechanical thrombectomy.The outcome is substantially better in TICI 3 than TICI 2b patients.
