目的探讨脑分水岭梗塞(CWI)的病因及临床特点。方法回顾性分析50例经头颅CT证实的CWI患者的病因及临床特点。结果CWI的病因为体循环低血压、脑的大动脉狭窄或闭塞、心脏疾患等。皮层前型18例(36%),临床表现为偏瘫、偏身感觉障碍、经皮层运动性失语等;皮层后型22例(44%),表现为视野缺损、皮质性感觉障碍等;皮层下型10例(20%),表现为轻偏瘫或偏身感觉障碍等。结论CWI的主要病因为体循环低血压、颈动脉狭窄或闭塞及心脏疾患。
Objective To investigate the etiology and clinical features of brain watershed infarction (CWI). Methods Retrospective analysis of 50 patients with CWI confirmed by skull CT etiology and clinical features. Results The causes of CWI were systemic hypotension, stenosis or occlusion of aortic stenosis, heart disease and so on. There were 18 cases (36%) of pre-cortical type. The clinical manifestations were hemiparesis, hemifacial sensation, transthoracic aphasia, etc .; 22 cases (44%) of cortical posterior cortex showed visual field defect and cortical sensory disturbance; Type in 10 cases (20%), manifested as hemiparesis or partial sensory dysfunction. Conclusions The main causes of CWI are systemic hypotension, carotid artery stenosis or occlusion and heart disease.
