Unstable carotid plaque resembling carotid web: a diagnostic challenge in acute ischaemic stroke with rapid response to tenecteplase.

We present the case of an African American man in his mid-to-late 40s with no prior vascular risk factors who developed an acute ischaemic stroke. Imaging revealed an unstable carotid plaque with an associated floating thrombus, resembling a carotid web. The patient demonstrated near-complete neurological recovery within 30 min following intravenous tenecteplase administration.

Anterior ischemic stroke: Analysis of the multivariable CT-based models for prediction of clinical outcome.

Objective: To determine the predictive value of multiple CT-based measurements, individually and collectively, including arterial collateral filling (AC), tissue perfusion parameters, as well as cortical venous (CV) and medullary venous (MV) outflow, in patients with acute ischemic stroke (AIS).

Methods: We retrospectively reviewed a database of patients with AIS in the middle cerebral artery distribution, who underwent evaluation by multiphase CT-angiography and perfusion. AC pial filling was evaluated using a multiphase CTA imaging.

Appearance of medullary and cortical veins on multiphase CT-angiography in patients with acute ischemic stroke.

Objective: We sought to determine if interhemispheric asymmetry of cortical and medullary veins evaluated on CT angiography can provide a more accurate prediction of outcome in patients with acute ischemic stroke when compared to hemispheric asymmetry of cortical or medullary vein drainage alone.

Methods: We retrospectively reviewed a database of patients with anterior circulation distribution acute ischemic stroke, who were evaluated by multiphase CTA. Cortical veins were evaluated using the adopted Prognostic Evaluation based on Cortical vein score difference In Stroke (PRECISE) system.
