目的探讨烟雾病合并后循环病变患者发生枕叶脑梗死的相关危险因素。方法 2003年5月至2013年5月收治烟雾病患者846例,合并后循环病变的患者258例,其中在后循环病变基础上伴发枕叶梗死107例,采用多因素Logistic回归分析对烟雾病合并后循环病变时发生枕叶脑梗死的相关危险因素进行分析。结果单因素分析结果显示高血压、吸烟史以及左、右侧前循环铃木分期和左、右侧后循环Magikura分级是烟雾病合并后循环病变致枕叶梗死发生的危险因素(P<0.05)。多因素Logistic回归分析显示高血压循环Magikura分级和年龄是其独立危险因素。结论烟雾病合并后循环病变继发枕叶梗死是多因素作用的结果,正确、全面地认识这些因素的作用有助于降低枕叶梗死的发生率。
Objective To investigate the related risk factors of occipital lobe cerebral infarction in patients with post-morbid gynecopathy. Methods From May 2003 to May 2013, 846 patients with moyamoya disease and 258 patients with combined pathological changes were enrolled. Among them, 107 cases of occipital infarction were found on the basis of retroperitoneal circulation disease. Multivariate Logistic regression analysis was used to analyze the effects of moyamoya disease Associated risk factors for occipital lobe cerebral infarction at the time of combined revascularization were analyzed. Results The results of univariate analysis showed that hypertension, smoking history, left and right anterior circulation SUZUKI staging and left and right posterior circulation Magikura classification were risk factors of occipital lobe infarction caused by recurrent moyamoya disease (P <0.05). Multivariate logistic regression analysis showed that the hypertension cycle Magikura grade and age were independent risk factors. Conclusions The secondary occipital lobar infarction is the result of multifactorial action after the combined disease of moyamoya disease and the correct and comprehensive understanding of these factors helps to reduce the incidence of occipital infarction.
