^（133）Xe吸入法测定脑出血的脑局部区域血流量

REGIONAL CEREBRAL BLOOD FLOW IN CEREBRAL HAEMORRHAGE MEASUREDWITH THE ￣(133)Xe INHALATION TECHNIQUE

对４０例高血压内囊－基底节区脑出血患者测定了脑局部区域血流量（ｒＣＢＦ），发现高血压内囊－基底节区脑出血病灶侧及病灶对侧大脑半球ｒＣＢＦ均明显低于同年龄正常人，尤以病灶侧为甚．脑血流降低程度与病情、血肿部位及出血量有关．病情重、丘脑出血或血肿大者，ｒＣＢＦ降低明显．内囊基底节区脑出血可引起病灶对侧小脑脑干血流量降低．

Abstract Measurement of regional cerebral blood flow (rCBF) was performed in 40 patientS with hypertensive intracerebral haemorrhage involving the internal capsule and hasal ganglia and in 40 normal subjects. The CBF of stroke hemisphere and non-stroke hemisphere in patients was reduced more obviously than hemispheric mean cerebral blood flow in normal subjects of the same age, particufarly in stroke hemisphere. The rCBF in cerebral haemorrhage correlated with the clinical scverity of illness, localization of haematoma and bleeding volume. The rCBF in cerebral haemorrhage was the least in severe cerebral haemorrhage of the thalamus and large haematoma. Cerebral haemorrhage in the internal capsule and hasal ganglia could result in rCBF reduction of cerebellar and brain stem on the contralateral side of the haematoma.
