[Abstract] Ischemic stroke (IS) is one of the leading causes of death and disability worldwide. Mechanical thrombectomy (MT) has become a cornerstone in the treatment of large vessel occlusion strokes; however, the risk of recurrence after the procedure significantly impacts patient prognosis. Therefore, accurate prediction and timely intervention of post-thrombectomy recurrence are crucial for reducing recurrence rates, lowering mortality risk, and optimizing treatment outcomes. The present review aims to systematically summarize current imaging approaches used to evaluate the risk of ischemic stroke recurrence after mechanical thrombectomy, analyze their mechanistic basis, technical features, and clinical applicability, with the goal of providing theoretical insights and imaging-based decision support for postoperative risk stratification and precise secondary prevention in stroke patients. Furthermore, this study highlights the limitations of existing research and discusses potential directions for future investigations.
