  • Note.—Cases of stents placed for intracranial carotid stenoses according to etiology of the stenoses (A indicates atherosclerosis; D, dissection); whether the stent was placed urgently (U) or electively (E); whether the case had prestent perfusion abnormality on imaging; whether the poststent perfusion abnormality normalized (2), improved (1), or did not change (0). The circle of Willis (COW) anatomy in each case is indicated by the presence or absence of anterior communicating artery (Acom) and number of posterior communicating arteries (Pcom). The presence of a functional COW means that there is either a competent Acom or presence of a Pcom ipsilateral to the stenosis. Time of imaging follow-up is the number of days from the procedure that the follow-up perfusion imaging was performed. Time of clinical follow-up is the number of months from the procedure that the IQ-CODE was administered. L indicates left; R, right; ICA, internal carotid artery.
