[An analysis of regional cerebral blood flows (rCBF) in 120 patients with cerebrovascular disease].
The rCBF in a group of 120 patients with cerebrovascular disease (CVD) diagnosed clinically as well as with CT scans and a group of 120 healthy subjects as controls was measured with the 133Xenon inhalation method. The result showed that the rCBF of the CVD group was significantly lower than that of the control group (P less than 0.01). The tally rate between the rCBF reduction areas and the lesion sites was 85 per cent. The areas of rCBF reduction measured with 133Xenon inhalation were larger than the extents of the lesions shown by CT scans in 47 cases of cerebral infarction. The rCBF reductions of bilateral cerebral hemispheres were found in 16 cases of cerebral infarction. The average hemispheric rCBF obviously decreased in 12 cases of multiple cerebral infarction with dementia, but showed no decrease of rCBF in 18 cases of small focal cerebral infarction.
