| Abstract | 「要旨」虚血性脳血管障害35例について, 133Xeガス吸入CBFとそのdelayed scan, X線CTスキャン, およびIVDSAなどを用いて, 壊死巣を含まない中大脳動脈領域虚血巣の血流量を検討した. 35例中の20例でacetazolamide静注によるactivation studyも施行した. CBF像で, 血流低下を示した症例のdelayed scanで, 患側と健側を比較すると, I型:患側の集積が健側に比べ多くなるもの, II型:患側が健側とほぼ等しくなるもの, III型:患側が低下したままであるものに区別できた. I型のIVDSA像で側副血行路の発達が良好であり, misery perfusionの状態であることが推定された. III型では側副血行路の発達が悪く, acetazolamideによる血管反応性も乏しく, perfusion reserveの低下が疑われた. したがって, I型では治療効果が期待できよう. |

| Abstract | [Summary]The cerebral blood flow study to detect ischemic areas in the brain was performed in 35 patients with occlusive cerebro-vascular disease in an unilateral internal carotid artery and/or middle cerebral artery; utilizing Single Photon Emission CT (SPECT) with 133Xe inhalation technique, with the additional delayed scan. In 20 cases of them the activation study with intravenous injection of acetazolamide 20 mg/kg was done. X-ray CT and in a part of the cases intravenous digital subtraction angiography (IVDSA) were also performed. The delayed scan images were classified into the following 3 types according to the amount of the accumulated activity on the affected side in comparison with the non-affected side.; Type I: a greater amount of accumulation of 133Xe in the affected side, Type II: an approximately equal amount of accumulation on both sides, Type III: a lesser amount of accumulation on the affected side. The collateral circulation demonstrated on the IVDSA images was relatively rich in the Type I group. A poorer collateral circulation on DSA and an impaired response to the activation study were shown in the Type III group. The Type I might be explained by the penumbra effect and might be considered as a candidate for bypass surgery. |
