Clinical efficacy and safety of endovascular treatment for patients with wake-up stroke with large vessel occlusion guided by NCCT-ASPECTS

Objective: To evaluate the clinical efficacy and safety of 6 to 24 h endovascular therapy (EVT) in patients with wake-up stroke (WUS) with acute large vessel occlusion (LVO) of the anterior circulation guided by noncontrast computed tomography-Alberta stroke program early CT score (NCCT-ASPECTS).

Methods: Fifty-three patients with WUS with acute LVO of the anterior circulation who were treated at the Sir Run Run Shaw Hospital of Zhejiang Medical College from January 2018 to March 2021 were retrospectively analyzed. The patients were divided into NCCT-ASPECTS or CT perfusion groups. Baseline data, perioperative data, and 90-d prognostic information were compared between the two groups. Multivariable logistic regression analysis was used to determine the independent factors influencing outcomes.

Results: There were no significant differences in the good prognosis, symptomatic intracranial hemorrhage, and mortality rates between the two groups (P > 0.05). Multivariate logistic regression analysis showed that the puncture-recanalization time was an independent factor for good prognosis.

Conclusion: Based on NCCT-ASPECTS guidance, EVT in patients with WUS for acute LVO of the anterior circulation within 6 to 24 h may be safe and effective.
