Napkin-ring sign plaques are associated with clinical outcome in patients with acute ischemic stroke after endovascular therapy

1

The study investigates the association between carotid artery napkin ring sign (NRS) plaques and outcomes in acute ischemic stroke patients undergoing endovascular therapy.
2

Higher total NRS plaques and areas were found on the symptomatic side compared to the contralateral side in patients with acute ischemic stroke.
3

Patients with poor outcomes exhibited a high percentage of total NRS plaques on both sides, indicating a correlation with adverse clinical results.
4

NRS plaque areas were significantly larger in patients with poor outcomes and effectively discriminated the presence of poor outcomes.
5

The presence and areas of NRS plaques were associated with reduced recanalization rates and increased symptomatic intracranial hemorrhage in patients after EVT.
