作者从541例已测量过局部脑血流的卒中患者中选取55例有系统脑血流资料者为研究对象。其中男35例,女20例,平均年龄62±11岁(36～86岁)。39例脑梗塞,16例脑出血。在首次测定大脑局部血流后的18到54个月(28±10个月)再次测定并探讨血压改变的可能影响。另选10名非卒中病人作对照组,平均年龄61±9岁,大脑血流测量间隔19～44个月(27±6月)。大脑局部血流测定采用~(133)Xe吸入法,气体中混入~(133)Xe(1.11×10~8Bq/L或3mCi/L),吸1min,多导程记录廓清曲线10min,经计算得单侧大脑半球血流平均值,同时测定血压、潮气末
The authors selected 55 patients with systemic cerebral blood flow data from 541 stroke patients who had measured regional cerebral blood flow. Including 35 males and 20 females, the average age of 62 ± 11 years (36 to 86 years old). 39 cases of cerebral infarction, 16 cases of cerebral hemorrhage. The potential impact of changes in blood pressure was measured again 18 to 54 months (28 ± 10 months) after the first determination of local cerebral blood flow. Another 10 non-stroke patients were selected as the control group, with an average age of 61 ± 9 years. Cerebral blood flow was measured between 19 and 44 months (27 ± 6 months). Local cerebral blood flow was measured by ~ (133) Xe inhalation method with ~ (133) Xe (1.11 × 10 ~ 8Bq / L or 3mCi / L) mixed in the gas for 1min. Unilateral cerebral hemisphere blood flow average, while measuring blood pressure, tidal end
