Abstract
Objectives: Assessment indication of evt based on clinical, simple images versus new information of Rapid ai software in ischemic stroke within 24 hour from onset. Subjects and methods: Including 61 patients with acute ischemic strokes admitted to the hospital within a time window of 24 hours from onset at the Stroke Center-Phu Tho Provincial General Hospital, from June 2021 to June 2022. Results: The majority of patients with unknown time of onset accounted for 41%, the rate of patients admitted within 6 hours was similar to the rate of patients admitted within 6-24 hours, respectively: 27, 9% and 31.1%. As the group of NIHSS scores increased, the Tmax > 6s also increased. There was no significant difference between volume mismatch and NIHSS score groups. There is a relationship between infarct core volume with ASPECT score and collateral circulation score with p < 0.01. Conclusion: ASPECT score ≥ 6 and collateral circulation score of moderate and good can predict infarct core volume in patients with extended treatment window. The NIHSS clinical grade scale is not related to the volume of penumbra, but is linearly correlated to the volume of infarct.
