摘　　要：目的探讨Willis环血流代偿与脑分水岭梗死短期预后的关系。方法对2012—2014年在大庆油田总医院神经内科住院的脑分水岭梗死患者进行头部CT血管成像检查(CTA),分析Willis环血流代偿情况对患者短期预后的影响。结果在95例脑分水岭梗死患者中,25.3%(24/95)前交通开放、24.2%(23/95)后交通开放、33.7%(32/95)前后交通均开放、16.8%(16/95)前后交通均不开放。71.6%(68/95)脑分水岭梗死病例预后良好、28.4%(27/95)预后不良。Willis环开放组与不开放组间预后不同(P<0.05)。结论 Willis环开放不良的脑分水岭梗死短期预后不佳,应多加关注。Objective To explore the relationship between circulation compensation in the circle of Willis and short-term prognosis of watershed infarction. Methods All patients who diagnosed as watershed infarction in Daqing Oilfield General Hospital between 2012 and 2014 were performed brain computerized tomography angiography（ CTA）. We analyzed the effect of Willis circle＇s compensatory circulation on short-term prognosis. Results In 95 cases of cerebral watershed infarction,there were 25. 3%（ 24 /95） with the opening of anterior communicating artery,24. 2%（ 23 /95） with the opening of posterior communicating artery,33. 7%（ 32 /95） with the opening of both anterior and posterior communicating artery,and 16. 8%（ 16 /95） with the nonopening of both anterior and posterior communicating artery. 71. 6%（ 68 /95） watershed infarction patients had good prognosis,28. 4%（ 27 /95） patients had poor prognosis. There was significant difference between patency and impotency of Willis circle（ P〈0. 05）. Conclusions Watershed infarction patients with impotency of Willis circle had a poor prognosis,we should pay more attention.
