脑梗塞的危险因素包括遗传、解剖和环境因素。为了检验侧支途径的解剖学变异是否为一侧颈内动脉闭塞病人脑梗塞的危险因素,作者评价了主要或辅助侧支血流模式与脑梗塞和放射学特性的关系,以确定特异性侧支途径在大脑半球灌注中的重要性。 研究病例取自美国斯坦福大学医院,29例病人因颈内动脉闭塞使32个半球受累。其中2例系双侧颈内动脉闭塞,另1例为巨大动脉瘤伴一侧颈内动脉闭塞。所有病人经血管造影证实。24例慢性颈内动脉闭塞,23例是动脉粥样硬化,1例系头颈部肿瘤放疗所致。5例急性颈内动脉闭塞,3例因脑动脉瘤治疗性气囊阻塞引起,2例为急性壁间动脉瘤。所有病人行脑部常规自旋回波程序MRI扫描
Risk factors for cerebral infarction include genetic, anatomical and environmental factors. To test whether the anatomical variation of collateral pathways is a risk factor for cerebral infarction in patients with one side of internal carotid artery occlusion, the authors evaluated the relationship of major or accessory collateral flow patterns with cerebral infarction and radiological characteristics to determine the specificity of the side The importance of the branch pathways in hemispheric perfusion. The study cases were taken from the Stanford University Hospital in the United States, and 29 patients suffered from 32 hemispheres due to occlusion of the internal carotid artery. Two of them were bilateral occlusion of internal carotid artery, the other one was giant aneurysm with occlusion of internal carotid artery. All patients confirmed by angiography. 24 cases of chronic internal carotid artery occlusion, 23 cases of atherosclerosis, 1 case of head and neck cancer caused by radiotherapy. 5 cases of acute internal carotid artery occlusion, 3 cases of cerebral aneurysm due to the treatment of air bag occlusion caused by two cases of acute wall aneurysm. All patients underwent routine brainwave spin echo MRI scan
