ISCHEMIC STROKE
The RESCUE BT trial was a multicenter, randomized, double blinded clinical trial conducted at 55 hospitals in China from October 2018 to October 2021. Details of trial design and topline results have been described previously.For the current post hoc study, additional inclusion criteria were, (6) diagnosis of intracranial large artery atherosclerosis as the mechanism of the index ischemic stroke, and (7) achievement of successful reperfusion at the end of the mechanical thrombectomy procedure. Successful reperfusion was defined as an eTICI grade of 2b50‐3, including 2b50 (substantial reperfusion, 50–89%), 2c (excellent reperfusion, 90–99%), and 3 (completely reperfusion, 100%).
