| Popis: | To assess the cerebral hemodynamic data associated with transient cerebral hemodynamic disturbance (TCHD), including cerebral hyperperfusion syndrome (CHS) and watershed shift ischemia (WSI), by whole-brain (WB) computed tomography perfusion (CTP) before and after revascularization for ischemic moyamoya disease.A total of 115 consecutive patients with ischemic moyamoya disease underwent revascularization. All patients underwent WB-CTP 24 hours before operation and on the day of onset of TCHD and 6 months after revascularization. The volumes of delay time (DT)3 seconds and mismatch and relative cerebral blood flow30% were calculated in 3 time points.Of the 115 patients, 18 115 had TCHD, comprising 10 with CHS and 8 with WSI. Compared with the brain volume of DT3 seconds before revascularization, the volume decreased significantly (P0.05) on the day of CHS. The volume of mismatch in 3 time points indicated no significant differences (P0.05). The volume of relative cerebral blood flow30% showed obvious differences of significance among 10 patients with CHS (P0.05) at 3 time points. In the WSI group, the volume of DT3 seconds, mismatch, and DT3 seconds showed significant differences, relatively (P0.05), at 3 time points. At the time of onset of TCHD, DT3 seconds and mismatch in the CHS group were dramatically lower than those in the WSI group (P0.05). DT3 seconds in the no-TCHD group showed significant differences (P0.05) at 3 time points.WB-CTP could be used to assess the cerebral hemodynamic characteristics before and after revascularization. DT3 seconds and mismatch played important roles in evaluating distinct features of TCHD. |
