During the enrollment process, demographic variables, vascular risk factors, baseline NIHSS score, treatment information, and workflow measures were recorded. To ensure consistency and reliability in the evaluation process, all imaging data were reviewed by the imaging core laboratory of the RESCUE BT. The determination of the occlusion site was made based on the findings from CT or MR angiography conducted upon admission, with specific classification into distinct categories including internal carotid artery (ICA), middle cerebral artery M1 segment (M1 MCA), or middle cerebral artery M2 segment (M2 MCA). The extent of ischemic injury was quantified by employing the widely recognized Alberta Stroke Program Early CT Score (ASPECTS). The evaluation of reperfusion status during the final angiography utilized the expanded Thrombolysis in Cerebral Ischemia (eTICI) score [
