Changes in perfusion by vascular territory. Significant time by surgical interactions were observed within the (A) middle cerebral artery (MCA) (p = 0.011) and (B) posterior communicating artery (PCA) (p = 0.039) territories, with weaker, nonsignificant changes in the (C) anterior communicating artery (ACA) territories (p = 0.164). (ASL = arterial spin labeling; wk = week.)

Changes in individuals’ subregions within the (left panels) middle cerebral artery (MCA) and (right panels) posterior communicating artery (PCA) territories. As shown, changes were most evident in subregions 9 (p < 0.001), 5 (p = 0.007), 6 (p = 0.011), and 4 (p = 0.090). (ASL = arterial spin labeling; wk = week.)
