Clinical outcome after large-vessel occlusive strokes depends on admitting clinical condition, successful recanalization, and robust collateral circulation. However, predicting successful recanalization and quantifying collateral status in the acute setting remain elusive. Successful recanalization has many predictive factors. ⋯ Patients with large-vessel occlusive strokes have variable clinical responses to fibrinolysis and thrombectomy. Independent predictive variables that can possibly alter clinical outcome appear to be successful recanalization and robust collateral circulation. Future studies that allow for better prediction of successful recanalization and quantification of collateral status may help clinical decision-making when evaluating large-vessel occlusions.
