晚近对缺血性中风发病机制的研究提示中风后的脑损害只不过是颅外病变的后果。颈部颈动脉病变的发生发展规律遂成为人们关注的中心。早期诊治颈部颈动脉病变目前已改变了缺血性中风的病程。通过早期诊断和早期手术治疗,使中风从不治成为可治,从可治成为可防,乃是近年来老年医学的重大成就之一。病因:一、颅外颈内动脉的上行性栓子:最 Recent studies on the pathogenesis of ischemic stroke suggest that brain damage after stroke is but a consequence of extracranial lesions. The occurrence and development of cervical carotid artery disease has become the focus of attention. Early diagnosis and treatment of cervical carotid lesions has changed the course of ischemic stroke. It is one of the major achievements of geriatrics in recent years that early diagnosis and early surgical treatment can make strokes definitive and that cure can be preventable. Cause: First, the extracranial internal carotid artery emboli: the most
