Abstract
Background: Futile reperfusion (FR) is becoming an urgent issue for acute ischemic stroke patients who underwent endovascular treatment (EVT). Although the recanalization rate has improved after EVT, it is far from translating to increased tissue reperfusion and functional independence. Summary: Many underlying mechanisms including the “no-reflow” phenomenon, poor collateral flow, venous dysfunction, and inflammation were proposed, but the pathophysiology of FR is still unclear. Clinically, reliable predictors are still yet to be identified, and ongoing trials on shortening the time delay and cytoprotection may provide novel ideas for interventions of FR. Key Messages: This review will summarize the latest advances in FR and hopefully shed light on potential interventions.
