缺血性中风分为短暂脑缺血发作(TIA)、进展型及完全型中风,轻者仅有一时性功能障碍,重者脑梗塞导致永久性损害,为害至巨。近年来对中风发病机制的研究提示:于大多数病例,中风后的脑损害只不过是颅外病变的后果。因此,各家的注意重心逐步从颅内转向颅外、特别是集中在颈部颈动脉的病变上,从而掀起了缺血性中风的预防性手术的高潮,使中风从不治成为可治,从可治而成为可防,乃是近年来老年医学的重大进展之一。兹将缺血性中风的发病机制和外科治疗进展简述如下: Ischemic stroke is divided into transient ischemic attack (TIA), progressive and complete stroke, light only temporary sexual dysfunction, severe cerebral infarction leads to permanent damage, damage to the giant. Recent studies on the pathogenesis of stroke suggest that in most cases, brain damage after stroke is but a consequence of extracranial disease. Therefore, the focus of attention of each family gradually shifted from the intracranial to the extracranial, especially in the lesions of the neck carotid artery, which set off a climax of preventive surgery for ischemic stroke so that stroke can be cured from no cure It is one of the major advances in geriatrics in recent years that can be cured and prevented. The pathogenesis of ischemic stroke and surgical progress are summarized as follows:
