目的研究老年人脑出血后脑血流量改变及影响因素。方法对４２例老年脑出血患者在发病１周内行单光子发射型计算机断层扫描（ＳＰＥＣＴ）、脑血流显像和ＣＴ扫描，部分进行动态观察。结果脑血流量下降范围１０例局限在病灶周围，３２例累及病灶以外区域，其中小脑失联络１１例，１～６个月复查仍见广泛的血流量下降，血流减少的范围及程度与出血部位、出血量密切有关。结论老年人脑出血后存在持久广泛的脑血流量下降。
Objective To study the cerebral blood flow changes and its influencing factors after cerebral hemorrhage in the elderly. Methods 42 cases of senile patients with intracerebral hemorrhage within one week after the onset of single photon emission computed tomography (SPECT), cerebral blood flow imaging and CT scan, part of the dynamic observation. Results The range of decrease of cerebral blood flow was limited to 10 cases around the lesion and 32 cases outside the lesion. Eleven cases were lost in the cerebellum. Extensive decrease of blood flow was observed in 1 ~ 6 months. The extent and extent of blood flow reduction and hemorrhage Location, the amount of bleeding are closely related. Conclusion There is a long-lasting decline in cerebral blood flow after cerebral hemorrhage in the elderly.
