  1. BMI: body mass index; CAD: coronary artery disease; DM: diabetes mellitus; HTN: hypertension; Hx: history; CVA: cerebral vascular accident; H&N RT: head and neck radial therapy; CCA: common carotid artery; TICI: the thrombolysis in cerebral infarction; ICA: internal carotid artery; ECA: external carotid artery.
  2. *Symptomatic disease: a hemispheric transient ischemic attack (distinct focal neurologic dysfunction) or monocular blindness persisting less than 24 h or a stroke with persistence of symptoms or signs for more than 24 h within the previous 120 days before the index procedure.
  3. #Cases with contralateral ICA total occlusion or ipsilateral ECA total occlusion were excluded in the related analysis.
  4. P value of comparing CANO patients with and without full collapse.
