TIMI, thrombolysis in myocardial infarction grading system.NIHSS, National Institutes of Health stroke scale.When recanalisation is partial the Mori classification is more refined in giving prognostic information. In both TIMI and Mori grading systems, reopening the artery was an independent predictor of a favourable clinical outcome (p50% (Mori 3) than in those with reperfusion <50% (Mori 2) (p = 0.008).Ĭonclusions: Both TIMI and Mori grading systems are useful for predicting outcome after stroke and IAT. Recanalisation was categorised as TIMI grade 0 in 17 patients (12%), TIMI 1 in 16 (11%), TIMI 2 in 83 (56%), and TIMI 3 in 31(21%). After three months the outcome was favourable (defined as modified Rankin scale score (mRS) ⩽2) in 85 patients (58%) and poor (mRS 3 to 5) in 44 (30%) 18 patients (12%) were dead. Results: The median NIHSS score on admission was 15 and the mean time from symptom onset to IAT was 242 minutes. Associations of the thrombolysis in myocardial infarction (TIMI) grading system and the Mori grading system with clinical outcome were compared. Methods: Clinical and angiographic findings and outcome were analysed in 147 patients with M1 or M2 segment occlusion of the middle cerebral artery treated with IAT. Background: Different grading systems of arterial recanalisation have never been compared in large series of stroke patients treated with intra-arterial thrombolysis (IAT).
