1. In a prospective cohort study of 91 patients with anterior circulation ischemic strokes that underwent magnetic resonance imaging (MRI), time of stroke onset was not significantly associated with size of core infarct volume on MRI. 2. The presence of collateral circulation was significantly associated with decreased infarct volume. Evidence Rating...
1. In a prospective study of 178 patients with ischemic stroke, complete reperfusion was seen in less than two thirds of patients with complete recanalization on computed tomography angiography. 2. Predictors of complete reperfusion were lower stroke severity score, lower clot burden, distal thrombus location, and small infarct and ischemic area. Evidence...
1. A diffusion weighted imaging (DWI) parameter of >70mL of infarct volume with a NIHSS score of >20 was a highly specific predictor of poor clinical outcomes at three months following acute ischemic stroke. 2. A perfusion weighted imaging (PWI) parameter of <50 mL of mean transit time (MTT) with a...
1. Patients with acute ischemic stroke presenting with proximal vessel occlusion, adequate collateral circulation, and small infarct size who received rapid endovascular treatment had significantly improved 90-day functional outcomes and reduced mortality when compared to those who received intravenous alteplase alone. Evidence Rating: 1 (Excellent) Study Rundown: Patients with acute ischemic...
1. Among patients with large vessel ischemic stroke and evidence of salvageable brain tissue on computed tomography (CT) perfusion imaging, endovascular thrombectomy following intravenous (IV) alteplase administration improved technical reperfusion and both early clinical and late functional outcomes when compared to IV thrombolytic therapy alone. 2. No significant differences in...
