High-resolution MRI study of stroke recurrence in patients with symptomatic atherosclerotic middle cerebral artery occlusion

Motivation: <ul _msthidden="1"><li _msttexthash="25570389" _msthash="119">The risk of stroke recurrence is high in patients with Symptomatic atherosclerotic middle cerebral artery occlusion(sAMCAO). Stratification of high-risk patients is crucial for reducing the risk of stroke recurrence. Goal(s): To identify the imaging features associated with stroke recurrence in patients with sAMCAO. Approach: <ul _msthidden="1"><li _msttexthash="19165211" _msthash="134">lThe patients were categorized into a recurrence group and a non-recurrence group, and factors associated with stroke recurrence were evaluated using multivariate logistic regression. Results: Plaque enhancement, the anterior circulation of the Willis circle (COW-A), and deep tiny flow voids (DTFV) were independently found to be associated with stroke recurrence. Impact: Plaque enhancement degree, incomplete anterior Circle of Willis circulation, and absent DTFV are independently linked to stroke recurrence in sAMCAO patients. HR-MRI evaluation of the occluded vessel aids in identifying imaging markers predictive of recurrence.
