COMPARISON OF THE ASPECT SCORING SYSTEM ON NONCONTRAST CT AND ON BRAIN CT ANGIOGRAPHY IN ISCHEMIC STROKE.

The ASPECTs scoring system has been used to prognosticate, for example the score is a strong predictor of functional outcome in acute anterior circulation ischemic stroke. The effectiveness of thrombolysis and thrombectomy in patients with middle cerebral artery occlusion shows effect modification by the Alberta Stroke Program Early CT Score. We compared the ASPECTs scoring system on noncontrast CT and on brain CT angiography (arterial phase-ASPECTAs) for predicting functional outcomes in acute anterior circulation ischemic stroke. 81 consecutive patients with acute anterior circulation ischemic stroke treated with thrombectomy during 2019-2020 were included. Two independent radiologists evaluated score by using the Alberta Stroke Program Early CT methodology on NCCT and CTA. Good and extremely poor outcomes at 3 months were defined by modified Rankin Scale scores of 0-2 and 5-6 points, respectively. Factors associated with outcome on univariable analysis were ASPECT, ASPECTAS, lower NIHSS scores, and time to recanalization. On multivariable logistic regression ASPECTAS ≥5 were independent predictors of good outcomes. ASPECTs scoring system on brain CT angiography (arterial ASPECTs) is superior than non contrast ASPECT for predicting of good outcome in pacients with acute anterior circulation ischemic stroke.
