Risk of symptomatic intracranial hemorrhage (sICH) according to thrombolysis in cerebral infarction (TICI). Data on sICH was available in 308/311 patients. SICH occurred in 5/33 patients (15.2%) with TICI0/1, in 8/66 patients (12.1%) with TICI2a, in 14/187 patients (7.5%) with TICI2b and did not occur in 22 patients with TICI3. There was a decreased risk of sICH with higher TICI grade (adjusted odds ratio [aOR] per grade increase derived from logistic regression analysis: aOR, 0.43; 95% confidence interval, 0.20 to 0.94). TICI scores used were before administration of intra-arterial fibrinolytics in cases of rescue of TICI0-2b reperfusions. In other cases (treatment of emboli in new territory or administration during first retrievals at the operator’s discretion) final TICI scores were used.
