| Abstract | 「要旨」脳梗塞患者の経過観察中に, 脳RIアンギオグラムが病巣部の灌流増加を示した症例を4例経験した. 灌流増加は, 発作後8日から17日に検査した時認められ, 脳スキャンも中大脳動脈領域に扇形集積増加を示した. 骨スキャン用剤である99mTc-EHDPや99mTc-MDPも著しい集積増加を示した. 脳RIアンギオグラムの灌流増加は, ぜいたく灌流を示していると考えられる. このような脳梗塞は, Yarnellらが提唱しているようにhot strokeと呼ぶのが良いと思われる. このような症例は, 日を経て再検すると脳RIアンギオグラムは正常あるいは灌流減少を示すようになり, 脳スキャンもいずれ正常化する. 筆者らの経験した3例は, 心疾患を有し脳塞栓が考えられ, 1例は梅毒の既往を有した内頸動脈閉塞症であったが, 臨床経過は4例とも良好であった. |

| Abstract | [Summary] Four patients of middle cerebral infarction showed hyperperfusion on radionuclide cerebral angiography and fan-shape accumulation at the area of middle cerebral artery on early and delayed brain scan. In these patients, bone scanning agents such as 99mTc-EHDP or 99mTc-MDP also prominently accumulated at the area of infarction. These findings were observed on the study when it was performed within seventeen days after attack, but reexamination tended to show-normal or decreased perfusion on radionuclide cerebral angiography and improve abnormal accumulation on brain scans. The clinical diagnosis of these tree patients were cerebral embolism with heart disease, but one patient was internal carotid artery occlusion. The prognosis of all patients were very good. The hyperperfusion on radionuclide cerebral angiography of these patients represents the luxury perfusion in the lesion and these infarction has been called hot stroke by Yarnell et al. |
