Diffusion weighted magnetic resonance imaging's (MRI) role in predicting subsequent strokes beyond the validated Canadian TIA Score in in transient ischemic attack (TIA)/minor stroke patients with normal CT scans is unknown. In this study, we assessed the incidence of acute cerebral infarction on MRI in these patients, overall and stratified by the Canadian TIA Score levels and then we assessed subsequent stroke rates at 7, 30 and 90 days based on the presence of acute infarct on MRI. ⋯ Combining the Canadian TIA Risk Score with follow-up MRI improves stroke risk assessment. MRI enhance the accuracy of diagnosis TIA, especially when CT is negative. The risk score helps prioritize MRI, benefiting medium-risk patients most, while high-risk patients need prompt management regardless of MRI results. Low-risk patients benefit from MRI for determining further investigations.

Perioperative Stroke Following Implantation of Left Ventricular Assist Device: A Retrospective Cohort Study.
Stroke is common following left ventricular assist device (LVAD) implantation, although comprehensive data on perioperative strokes in this uncommon population is lacking. The current study aim was to characterize the presentation, features, and outcomes of perioperative cerebrovascular ischemia post-LVAD implantation at the authors' institution. ⋯ LVAD patients carry a high risk of perioperative stroke. They experience delayed recognition and diagnosis, limited intervention, and poor outcomes. Frequent neurological assessment and a low threshold for neuroimaging are prudent.

Postinterventional Petechial Hemorrhage Associated With Poor Functional Outcome After Successful Recanalization Following Endovascular Therapy.
Endovascular therapy (EVT) has emerged as the standard for treating patients with acute ischemic stroke due to large vessel occlusion. The aim of this study was to investigate the relationship between early petechial hemorrhage and patient outcomes after successful EVT of anterior circulation. ⋯ In patients with anterior large vessel occlusion who underwent successful EVT, petechial hemorrhage was associated with poor functional outcome and 90-day mortality when adjusted for complete recanalization, pre-EVT National Institute of Health Stroke Scale/Score, and Alberta Stroke Program Early Computed Tomography Score. Despite the relatively lower rate of a favorable 90-day outcome with petechial hemorrhage compared with no petechial hemorrhage, the absolute rate of a favorable outcome exceeds the natural history of medical management for this condition.
