Relationship between cerebral hyperperfusion (HP) on postoperative 123I-IMP SPECT imaging or cerebral hyperperfusion syndrome and preoperative RCVCRhypocap in the MCA ROI of the precentral region perfused by an anastomosed MCA. Closed and open circles denote patients with and without cerebral hyperperfusion syndrome, respectively. Upper and lower dotted horizontal lines denote upper and lower limits of the 95% confidence interval of control values obtained from healthy subjects, respectively.
