Clinical and Perfusion Mismatch Criteria Both Are Reliable in Identifying Patients Who Will Benefit from Endovascular Therapy.

Since 2015, when multiple clinical trials were published showing the efficacy of endovascular thrombectomy (EVT) for large vessel occlusion within six hours of stroke onset, additional criteria have been developed to identify those patients who will benefit from EVT beyond six hours. The AURORA investigators collected patient data from six large clinical trials and performed a meta-analysis to determine if a clinical mismatch or an imaging mismatch protocol was better at predicting good outcomes in patients treated between six hours and 24 hours after the onset of clinical stroke symptoms.
