title: [An evaluation of cerebral blood flow and metabolism of reconstructive vascular surgery using positron emission tomography--a report of 4 cases].
abstract: Changes in cerebral hemodynamics due to reconstructive cerebral vascular surgery were evaluated using positron emission tomography (PET). Three minor stroke cases and 1 TIA case, brought on by main trunk stenosis, were included. STA-MCA anastomoses was performed in two of the cases and carotid endarterectomy was performed in the remaining two cases. CBF, CBV, OEF, CMRO2 and CBF/CBV were investigated using PET with the ROIs fixed in both normal and stenosis areas. On the two cases of STA - MCA anastomosis, clear hemodynamic improvement was not demonstrated. On the two carotid endarterectomy cases, the hemodynamic factors showed improvement.
