Note: Smokers were defined as active smokers at the time of diagnosis. Patients receiving anticoagulants were those receiving this treatment at the time of acute stroke. Assessment with CT perfusion imaging is subjective with color maps and was not used to exclude patients. Time to imaging diagnosis was measured in minutes from symptom onset until identification of the occluded artery in CT angiography postprocessing. Treatment-related variables and postoperative variables included the presence of symptomatic intracranial hemorrhage and outcome measured by the modified Rankin scale at 90 days.

TICA: terminal internal carotid artery; ASPECT: Alberta Stroke Program Early CT Score; NIHSS: National Institute of Health Stroke Scale; IQR: Interquartile range; SD: Standard Deviation; TICI: thrombolysis in cerebral infarction scale; ICHs: intracranial symptomatic scale; mRS: modified Rankin Scale.
