Pre-treatment MRI-defined brain frailty and thrombectomy outcomes: a multicenter study using STRIVE-2 criteria
Background: Mechanical thrombectomy (MT) is the standard of care for large vessel occlusion (LVO) stroke, yet nearly half of patients fail to achieve functional independence. Cerebral small vessel disease (CSVD) represents a marker of brain frailty that may impair recovery. Objective: We aimed to evaluate whether compr...
