Validation of CT perfusion-based vascular territory mapping: correlation to visual pial grading and outcome measures.

Vascular territory mapping (VTM) software estimates which intracerebral vessel provides peak arterial flow to a brain voxel. This observational study was performed to assess the hypothesis that the VTM algorithm may correlate to visual measurements of leptomeningeal grading and stroke outcome measures in acute middle cerebral artery (MCA) occlusion. VTM software assigned regions of the brain to an estimated feeding intracerebral vessel.

Post-Thrombectomy Mild Hypercapnia State Prevents Poor Outcome by Reducing Infarct Progression.

Objective: In endovascular therapy (EVT) for stroke, futile recanalization contributes to poor prognosis. Mild hypercapnia may enhance cerebral blood flow and prevent ischemia, but its impact on prognosis in successfully recanalized EVT patients is unclear.

Methods: We retrospectively analyzed 237 patients from the INSPIRE database who underwent successful recanalization at our center (October 2018-March 2022).

The standardized letter of evaluation (SLOE) in emergency medicine: The internal validity of the SLOE 2.0.

Background: The standardized letter of evaluation (SLOE) is a crucial component of emergency medicine (EM) residency applications. Initially developed in 1995 and revised to electronic SLOE (eSLOE) 2.0, this tool aims to provide a standardized evaluation of medical students.

Late Endovascular Treatment for Ischemic Stroke with Moderate to Large Infarct Volume is Associated with a better Clinical Prognosis.

Objective: The concept of "time is brain" is crucial for the reperfusion therapy of ischemic stroke. However, the Infarct Growth Rate (IGR) varies among individuals, which is regarded as a more powerful factor than the time when determining infarct volume and its association with clinical outcomes. For stroke patients with a similar infarct volume, a longer time from stroke Onset to Imaging (OTI) correlates with a lower IGR, which may indicate a better prognosis.
