【摘要】 目的:分析脑分水岭梗死(CWI)血管造影的表现,探讨脑分水岭梗死与脑血管狭窄的相关性。方法:回顾性分析32例经CT或MR证实的CWI患者的脑血管造影表现。结果:32例CWI患者中发现28例(87.5%)有脑血管狭窄或者闭塞,4例(12.5%)血管造影正常。前循环大脑中动脉和颈内动脉受累最为常见。后循环受累的血管中以椎动脉最为常见。结论:脑分水岭梗死血管造影显示大部分患者有肯定的脑血管狭窄或者闭塞,及时行脑血管造影检查有利于指导治疗,判断预后。更多还原

【Abstract】 Objective:To analyze angiographic findings of cerebral watershed infarction (CWI) in order to understand the relationship between CWI and cerebrovascular stenosis.Methods:The results of cerebral angiography of 32 cases of CWI confirmed by CT and MRI were analyzed retrospectively.Results:28 cases (87.5%) of 32 showed cerebrovascular stenosis or occlusion and the other 4 cases (12.5%) without abnormality.The internal carotid arteries and middle cerebral arteries were most frequently involved in the anterior circulation.The vertebral arteries were the most commonly involved in the posterior circulation.Conclusion:Most patients of CWI were documented with definitive stenosis or occlusion of cerebral arteries.The prompt examination of cerebral angiography will be helpful for guiding treatment and judging prognosis.更多还原
