OBJECTIVE: To identify a proximal anterior circulation occlusion for effectively administering immediate mechanical thrombectomy by developing a novel, simple diagnostic scale to predict the occlusion, to compare its validity with available scales, and to assess its utility. METHODS: AA was applied to a prospective cohort of 259 patients from 3 stroke centers for external validation. The utility of the scale as an in-hospital triage was compared for the temporal factors of 158 patients with the occlusion. CONCLUSION: AA scale showed high sensitivity and specificity when an optimal cutoff score was used and was useful as an in-hospital triage tool.

Ohta et al. (2019) conducted a cohort in Proximal anterior circulation large vessel occlusion (n=259). GAI2AA diagnostic scale vs. Available clinical scales was evaluated on Prediction and in-hospital triage of proximal anterior circulation large vessel occlusion (p=<0.001). The GAI2AA clinical scale demonstrated high sensitivity and specificity for predicting large vessel occlusion and was useful as an in-hospital triage tool in 259 patients (P<0.001).
