目的 探讨脑分水岭梗死（ＣＷＩ）的类型和临床特点。方法 分析１９２例经ＣＴ或磁共振成像（ＭＲＩ）证实的ＣＷＩ临床资料及影像学改变。结果 皮层前型６９例，占３５．９％，病灶在大脑前动脉和大脑中动脉边缘区，呈楔形。临床表现偏瘫、经皮层运动性失语、智能减退等症状。皮层后型７４例，占３８．５％，病灶在大脑中动脉和大脑后动脉边缘区，呈楔形，临床以轻偏瘫、情感淡漠为主要表现。皮层下型４９例，占２５．５％，病灶在大脑中动脉皮层支与深穿支的边缘带，常位于额角后外方和基底节区，呈长条状、三角形。结论 ＣＷＩ的临床表现复杂，诊断主要依据ＣＴ或ＭＲＩ。
Objective To investigate the types and clinical features of cerebral watershed infarction (CWI). Methods The clinical data and imaging changes of 192 patients confirmed by CT or magnetic resonance imaging (MRI) were analyzed. Results The pre-cortex type 69 cases, accounting for 35.9%, lesions in the anterior cerebral artery and middle cerebral artery marginal area, was wedge-shaped. Clinical manifestations of hemiplegia, cortical aphasia, mental retardation and other symptoms. There were 74 cases of posterior cortex, accounting for 38.5%. The lesion was wedge-shaped in the middle cerebral artery and the posterior cerebral artery. The main clinical manifestations were hemiparesis and indifference. Subcortical type in 49 cases, accounting for 25.5%, the lesion in the middle cerebral artery cortex branch and the deep perforation of the marginal zone, often located in front of forehead outside and basal ganglia, was elongated, triangular. Conclusions The clinical manifestations of CWI are complex and the diagnosis is mainly based on CT or MRI.
