Summary
CBF reductuon was more marked in the thalamus and putamen than in the hemisphere and cortex, and CBF enhancement by Diamox was impaired in the formers and preserved in the latters. The resting and enhanced CBF was restored after surgery. ICP was within normal limits. CBF in the thalamus and putamen correlated negatively with the slow waves in the frontopolar, frontal and central regions on the side with the hematoma. CBF in the other regions and on the side without the hematoma had no correlation with any EEG quotinent. fe speculate that chronic subdural hematoma displaces and distorts the central cerebral areas without significant increase of ICP, and has them dys- functioned. The other brain structures including the cortex seem to undergo a trans- neuronal suppression from the dysfunctioned thalamus with a resulting reduction of CBF.
