Abstract 081: Circle of Willis Arterial Size is Associated with Symptomatic Status in Chronic Carotid Occlusions

Patients with chronic carotid occlusion (CCO) may present as either symptomatic or asymptomatic, with significant differences in prognosis and treatment strategies between these groups. Anterograde collateral circulation, particularly through the Circle of Willis (CoW), is essential for sustaining adequate cerebral blood flow in CCO patients. This study aimed to evaluate the association between collateral pathways within the CoW and the symptomatic status of patients with CCO.
