  • Abstract
  • Look Inside

The ischemic area surrounding the cerebral infarction in the eloquent area was salvaged by STA-MCAbypass surgery. Both the misery perfusion area evaluated by positron emission tomography (PET) usingthe [1501 gas inhalation steady-state method and clinical symptoms improved within a year after surgery.

To confirm the ischemic area and select the suitable recipient artery was important for successful bypasssurgery, because only an artery covering the ischemic area is expected to have low resistance. In this casea large ischemic area with disturbed vasodilatation by Diamox was detected on the SPECT. However,PET clearly exposed the localized misery perfusion area in the overestimated ischemic area by SPECT.We describe our experience and discuss the technique and efficacy of PET for STA-MCA anastomosissurgery.
