目的：旨在提高大脑动脉闭塞的CT诊断水平。材料与方法：对36例临床上诊断或怀疑有脑梗塞、脑溢血、转移性肿瘤、脑脓肿等患者作CT平扫，有的作2～4次。其中6例作增强扫描。结果：大脑中动脉闭塞25例，其中7例引起出血性脑梗塞；大胸前动脉闭塞6例；大脑后动脉闭塞1例；大脑中动脉和前动脉均闭塞2例；既有大脑中动脉闭塞，又有大脑后动脉出血1例：开始为腔隙性脑梗塞，后又有大脑前动脉闭塞1例。结论：1、大脑动脉闭塞，特别是有出血性脑梗塞的临床表现与脑溢血常混淆，即使是有经验的神经内科医师有时也要引起误诊。2、用窄窗观察和CT追踪复查是显示缺血性脑梗塞和出血性脑梗塞的重要手段。3、当临床表现不能由腔隙性脑梗塞作出解释时，应再作CT复查，看是否还有大脑动脉闭塞引起缺血性脑梗塞。4、出血性脑梗塞往往发生于缺血性脑梗塞后2周左右，因此必须进行CT复查。5、引起大脑动脉闭塞的原因很多，必须结合临床资料才能明确。
Objective: To improve the CT diagnosis of cerebral artery occlusion. Materials and Methods: Thirty-six patients with clinically diagnosed or suspected cerebral infarction, cerebral hemorrhage, metastatic tumors and brain abscesses underwent CT scan. Some patients underwent CT scan two to four times. Six cases of enhanced scanning. Results: 25 cases of middle cerebral artery occlusion, of which 7 cases of hemorrhagic cerebral infarction; large anterior occlusion in 6 cases; cerebral artery occlusion in 1 case; middle cerebral artery and anterior artery occlusion in 2 cases; both middle cerebral artery occlusion , There are 1 case of posterior cerebral artery hemorrhage: beginning of lacunar infarction, followed by anterior cerebral artery occlusion in 1 case. Conclusions: 1. Cerebral artery occlusion, especially the clinical manifestation of hemorrhagic cerebral infarction, is often confused with cerebral hemorrhage. Even experienced neurologists sometimes cause misdiagnosis. 2, with narrow window observation and CT tracing review is an important means to show ischemic cerebral infarction and hemorrhagic cerebral infarction. 3, when the clinical manifestations can not be explained by the lacunar infarction, CT should be re-examined to see if there are cerebral infarction caused by cerebral infarction. 4, hemorrhagic cerebral infarction often occurs in ischemic cerebral infarction about 2 weeks, it must be CT review. 5, caused by cerebral artery occlusion for many reasons, must be combined with clinical data to be clear.
