极小小脑梗塞是发生于小脑供应动脉之间的边缘区小梗塞。梗塞原因多数为大动脉的动脉粥样硬化,少数为高凝状态或微栓塞引起的终末动脉闭塞。梗塞部位在小脑上动脉、小脑后下动脉和小脑前下动脉分支之间的边缘区。皮质梗塞多于白质梗塞。临床表现与大范围小脑梗塞大致相同。 Minimal cerebellar infarction is a small infarct of the marginal zone that occurs in the cerebellar supplying artery. Most of the causes of infarction, aortic atherosclerosis, a few hypercoagulable state or micro-embolization caused by terminal arterial occlusion. The infarct is in the marginal zone between the superior cerebellar artery, posterior inferior cerebellar artery, and branch of the anterior inferior cerebellar artery. More cortical infarction than white matter infarction. Clinical manifestations and a wide range of cerebellar infarcts are roughly the same.
