高血压脑出血患者脑局部区域血流量测定

MEASUREMENT OF REGIONAL CEREBRAL BLOOD FLOW IN CEREBRAL HAEMORRAGE WAS MEASURED WITH 133XE NON-INHALATION TECHNIQUE

报告４０例高血压内囊基底节区脑出血的脑局部区域血流量（ｒＣＢＦ），发现高血压内囊－基底节区脑出血病灶侧及病灶对侧半球ｒＣＢＦ均明显低于同年龄正常人，尤以病灶侧为甚。影响脑血流降低程度的因素为病情程度，血肿部位及量，病情重者、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。

easurement of regional cerebrel blood fIow(rCBF)was performed in 40 patientswith hypertensive intracerebral haemorrhage involving the internal capsule and basalganglia and in 40 normal subjects rCBF of stroke and non-stroke hemisphere in patients’group was reduced more obviously than the hemispheric mean cerebral blood flow innormal subjects group of same age particular in stroke hemisphere,rCBF in cerebral haemo-rrhage correlated with clinical severity of illness,localization of haematoma and bleed-ing volume,rCBF in cerebral haemorrhage was the least in severe cerebral haemorrhage,haematoma of the thalamus and large haematoma. Cerebral haemorrhage in the internalcapsule and basal ganglia could result in rCBF reduction of cerebellar and brain stemof contralateral side of the haematoma.
