From December 1985 to May 1986, cerebral blood flow (CBF) was studied in 11 patients with occlusive cerebrovascular diseases confined by angiography. 133Xe (5mci) intravenous injection method designed by Kuikka and coworkers was applied for the measurement of regional-CBF and mean-CBF, and the calculation was based on the initial slope index. They were composed of 4 patients of the middle cerebral artery occlusion, 2 of the posterior cerebral artery occlusion, 1 0f the internal carotid artery occlusion, 2 0f the middle cerebral artery stenosis, 1 of the internal carotid artery stenosis, and 1 of the anterior cerebral artery stenosis. The period from the vascular attack to the initial CBF study was 2-29days(mean 9.2days). 1) Recovery of mean-CBF was correlated with clinical and neurological improvement, and vice versa. 2) There was no correlation between mean-CBF and neurological severity. CBF study alone is not sufficient to evaluate neuronal conditions in the occlusive disease. Additional other means, such as CT-scan, angiography and etc. should be requested for it. 3) Intravenous 133Xe injection technique has an advantage over intracarotid injection method; less dangerous, especially in ages and capable of simultaneous measurement of bilateral hemisphere. 4) Considering cross talk regional-CBF of a low density area on X-ray CT-scan was equal to the one obtained by intracarotid injection method.
