Abstract 3: Effect of BP Goal on Outcome post Mechanical Thrombectomy: Multicenter Study

Introduction: Current AHA/ASA guidelines recommend keeping blood pressure (BP) <180/105 after successful recanalization with MT. However, due to a concern of reperfusion injury, different BP goals are utilized across various endovascular centers. In this study, we compared functional and hemorrhagic outcomes between different BP goals. Methods: This was a multicenter international retrospective study that included 7 comprehensive stroke centers. Inclusion criteria were anterior circulation large vessel occlusion (LVO) that was treated with MT, and successful recanalization at the conclusion of the procedure. Patients were divided into three groups based on systolic BP (SBP) goals in the first 24 hours post MT. Group 1) included patients with SBP goal ≤140 mm Hg or ≤120 mm Hg; group 2 included patients with SBP goal ≤160 mm Hg; group 3) included patients with SBP goal ≤220 mm Hg or ≤180 mm Hg. Successful recanalization was defined as TICI 2b-3. Outcome measures included symptomatic intracerebral hemorrhage...
