Thrombus enhancement as a predictor of embolic in acute basilar artery occlusion.

ABSTRACT: Thrombus enhancement sign (TES) is a potential imaging biomarker for differentiating embolic large vessel occlusion (embo-LVO) from intracranial atherosclerosis-related LVO (ICAS-LVO) in basilar artery occlusion (BAO). This study evaluates the association between TES and BAO etiology and its predictive value in distinguishing embo-LVO from ICAS-LVO. We conducted a prospective, two-center cohort study of acute ischemic stroke (AIS) patients with BAO who underwent EVT between January 2020 and September 2024. TES was assessed using thin-section maximum intensity projection (TS-MIP) CTA. Patients were classified as embo-LVO or ICAS-LVO based on post-EVT angiography. Logistic regression, receiver operator characteristic curve (ROC) and DeLong test were used to assess TES's diagnostic accuracy.
