Compared with the symmetric group, the AA1 and AA2 groups had a significantly larger ICA diameter on the dominant side and a significantly smaller ICA diameter on the non-dominant side. Similarly, significant differences in bilateral ICA flow were also found in the AA1 and AA2 groups (Fig. 3b). The average bilateral ICA flow volume difference percentages of the AA1, AA2, and AA3 groups were 42.9, 30.7, and 29%, respectively (Table 2). A greater asymmetry between the bilateral A1 segments tended to be associated with a larger difference between the bilateral ICA flow volume.\nFig. 3 Vessel diameter and flow in each group of COW variants.
