| Abstract | 中大脳動脈閉塞や狭窄の20例（55.3±7.4才）の慢性期の脳血管撮影（CAG）, CTや局所脳血流（rCBF）所見から脳循環動態を検討した. rCBFはDI（diffuse ischemic pattem 全般減少）型：Fg55.5±5.2（SE）ml／100g／min 6例；FI（focal ischemic pattern 部分減少）型71.6±5.9, 10例；NP（normal pattern 正常）型81.8±7.4, 4例に分類された（各群間P＜0.001）. DI型では基底核や脳室周辺に低吸収域が多発し血管狭窄も高度でcollateral flow（CF）も発達不良であった. FI型では血管狭窄も種々で脳室周辺や脳表にLDA（CT上のlow density area）が多くNP型と同様CFは発達良好であった. 臨床症状は必ずしもrCBF低下の程度と一致しなかった. rCBF減少の要因としてdeactivationによる代謝低下, CF発達の差異及び局所CF阻害因子などが考えられた. |

| Abstract | Twenty patients of mean 55.3 years-old with chronic occlusion or stenosis of middle cerebral artery were included in this study. Their cerebral hemodynamics were estimated by measurements of regional cerebral blood flow（r-CBF；Fg） and findings of cerebral angiography as well as CT. Their neurological states were complete stroke（11 cases）, RIND（7） and TIA（2）. Patients were classified into three categories from significant differences in r-CBF values. Diffuse Ischemic pattern（DI：6 cases）, Focal Ischemic pattern（FI：10 cases） and Normal pattern（NP：4 caese）. R-CBF values were most lowest in DI, while those in FI were lower than NP. CT-lesions seated in basal ganglias were frequently found in DI group followed by FI group. But none of NP group showed such a lesion. Severe stenosis or poor development of collateral flow were most prominent findings in DI group. A low density area in watershed zone was distributed equally through 3 groups. However, degrees of symptoms were not so well correlated with decreasing of rCBF. |
