Abstract only BACKGROUND: In acute thromboembolic stroke, mechanical recanalization with retrieval stents may result in immediate flow restoration. A selection criteria to treatment is a small volume of infarct in baseline CT scan, usually it is identified as an infarct 7). We assess whether evaluation of basal and 24h CT using Alberta Stroke Program Early Computed Tomography Score (ASPECTS) have predictive value for functional independence after stroke on noncontrast CT (NCCT). METHODS: We performed an retrospective analysis of 257 consecutive patients treated with thrombectomy (Solitaire, Trevo) , from April of 2010 to June of 2013, that met inclusion criteria for intervention. Vessel patency pre and post procedural were measured by TIMI and TICI score.Successful recanalization (TICI 2b-3), functional and clinical good outcome (mRankin 0-2) and mortality at day 90 and symptomatic hemorrhage were prospectively assessed. We evaluated baseline NCCT, mean final infarct extension measuring by 24h-ASPECTS and change in ASPECTS from baseline to 24h CT. RESULTS: A total of 168 patients with ischemic stroke of the MCA territory (M1 segment or terminal internal carotid occlusion) were included in this study. We calculated ASPECTS mismatch as 24H NCCT ASPECTS/Baseline NCCT ASPECTS*100. Low percentage represents a reduced infarct and an higher efficacy of the neurointerventionism (TICI 2b-3, p:0.001) . Basal and 24h ASPECTS were dichotomized at >=8 vs =8 in NCCT ASPECTS implied a higher probability of an independent functional outcome at 90 days (mRankin 0-2) when compared to
