| The circle of Willis can be divided into 4 types: complete (type I), anterior complete (type II), posterior complete (type III), and anterior and posterior incomplete (type IV). According to the literature, type I was defined as better integrity of the circle of Willis, type II and III were defined as good integrity of the circle of Willis, and type IV was defined as poor integrity of the circle of Willis. slow collateral blood supply to the periphery of ischemic area, fast collateral blood supply to the periphery of ischemic area, slow collateral blood supply to the whole ischemic area, and Level 4: fast collateral blood supply to the whole ischemic area. | ||||
