Flores A, Ustrell X, Sero L, et al. - The present study was conducted to distinguish factors related to partial or complete recanalization (REC) at comprehensive stroke center (CSC) arrival in patients with a documented large vessel occlusion (LVO) in primary stroke center (PSC) transferred for endovascular treatment (EVT) assessment to better characterize the workflow at CSC of this group of patients. Between January 2017 and June 2019, researchers performed an observational, multicenter study from a prospective, government-mandated, population-based registry of stroke patients with documented LVO at PSC transferred to CSC for EVT. They assessed the relationship between baseline, treatment variables, and time intervals with the presence of REC. A total of 589 patients were included in the study. The data exhibited that REC at CSC arrival occurs exceptionally in patients with a documented LVO on PSC. The results exhibited that in most patients, repeating a second vascular study before EVT would not be necessary. The results demonstrated that despite its modest impact, tPA treatment at PSC was an independent prognosticator of REC.
