Observational StudyGood Clinical and Radiological Correlation from Standard Perfusion Computed Tomography Accurately Identifies Salvageable Tissue in Ischemic Stroke.
It has been debated whether the penumbral pattern, as identified using multimodal imaging, is a specific marker of tissue viability in ischemic stroke. We assessed whether perfusion computed tomography (PCT) accurately identifies salvageable tissue and helps predict postreperfusion outcomes. ⋯ PCT provides accurate markers of viability of tissue in acute ischemic stroke and could help predict the degree of improvement following reperfusion.

Comparative StudyA Retrospective Cohort Study on the Use of Intravenous Thrombolysis in Stroke Mimics.
The urgency of intravenous thrombolysis in acute ischemic stroke can lead to inadvertent thrombolysis of patients with nonstroke diagnoses (stroke mimics), increasing the risk of adverse events. The objectives of this study were to compare thrombolysed acute ischemic stroke and stroke mimic cases based on demographic factors, physiological parameters, radiological findings, and clinical presentation, and to evaluate the clinical implications of thrombolysing stroke mimics. ⋯ Despite similarities in clinical presentation, thrombolysed stroke mimics are of a different physiological and demographic population, and are associated with fewer adverse events compared with thrombolysed acute ischemic stroke patients.

Incidence and Risk Factors of Perioperative Stroke in Noncardiac, and Nonaortic and Its Major Branches Surgery.
Perioperative stroke, defined as a stroke that occurs during an operation until 30 days postoperatively, is an uncommon but devastating complication. Studies regarding perioperative stroke in noncardiac and nonmajor vessels surgery are scarce. ⋯ The incidence of perioperative stroke found was comparable to the previous similar studies. Advanced age, pre-existing valvular heart disease, previous stroke, emergency surgery, and postoperative hypotension were the significant risk factors determined in this study.
