“…This study showed that patients in the complete circle of Willis group had better neurological recovery, which was consistent with the study results of Chuang et al 23 However, Chuang et al investigated patients with acute noncardiac cerebral infarction who received intravenous thrombolysis. The enrolled subjects had to satisfy specific inclusion criteria.…”

“…First, a complete circle of Willis has better collateral circulation and higher compensatory capacity in the case of cerebral ischemia, enabling a greater chance of collateral reperfusion to the ischemic penumbra and minimizing neurological impairments. Second, a complete circle of Willis indicates that more blood flow is available to form collateral pathways via the circle of Willis, creating the conditions for reperfusion to the cerebral ischemic lesions 23 and helps to improve the hemodynamics of artery anastomoses in the pia mater, improving the compensatory capacity of collateral anastomoses in the pia mater to the infarct vessels. Third, a complete circle of Willis reduces cerebral ischemia-reperfusion injury 24 and counteracts the hemodynamic changes of cerebral ischemia and reperfusion, reducing brain damage.…”

“…[23] Patients with better collaterals were not prone to having hemorrhagic complications after acute reperfusion therapy. [24,25] Moreover, the brain histopathological changes after stroke onset may be different between both circulation territories. Previous studies have suggested a delayed blood–brain barrier disruption in posterior circulation compared with anterior circulation.…”

“…recovery level of patients in occlusive vascular diseases may be explained with some variations in the circle of Willis. Chuang et al found that patients with a complete circle of Willis were more likely to have early improvement than the incomplete group in ischemic stroke patients (7). stroke is one of the most serious cerebrovascular diseases in Turkey, and the frequency of stroke in the posterior circulation is greater among people from Asian races compared to the west.…”
