急性脑梗塞尽管病因多样,但中心的病理生理过程都是局部脑血流量的减少。但脑血流量增加对脑功能的影响结论不尽一致。本文应用单光子发射计算机断层扫描对60例急性大脑中动脉供血区梗塞患者进行了脑血流量测定,并在病程的不同时期进行了神经功能缺损程度评分,以探讨脑梗塞急性期脑血流量的变化对预后的影响。 1 资料与方法 1.1 一般资料:选择首次发病临床及脑CT确诊的大脑中动脉供血区梗塞的病人60例,其中大脑中动脉主干梗塞、深穿支梗塞和皮层支梗塞各20
Acute cerebral infarction Although the etiology is diverse, the central pathophysiological process is a reduction in local cerebral blood flow. However, the effect of increased cerebral blood flow on brain function is not consistent. In this paper, single photon emission computed tomography was used to measure cerebral blood flow in 60 patients with acute middle cerebral artery occlusion and to evaluate the degree of neurological deficits at different stages of the disease to explore the cerebral blood flow in the acute phase of cerebral infarction Impact of changes on prognosis. 1 Materials and Methods 1.1 General Information: Select the first clinical and brain CT diagnosis of cerebral infarction in the middle cerebral artery occlusion in 60 patients, including the middle cerebral artery infarction, deep-branch infarction and cortical infarction of 20
