摘　　要：目的探讨脑分水岭梗死的临床特点和影像学特征。方法分析126例诊断明确的CWI患者的临床资料及影像学特点。结果CWI临床症状与体征取决于损害部位及梗死程度。126例中,104例为单侧病灶,主要临床类型有皮层前型27例(21.4%)、皮层后型31例(24.6%)、皮层下型46例(36.5%)。各型的影像学表现各有不同。结论CWI的临床表现、预后与头颅CT及MRI密切相关,及时行CT、MRI检查有利于指导治疗,判断预后。Objective To investigate the clinical and imaging characteristics of cerebral watershed infarction(CWI).Methods Analysis of the clinical data and imaging characteristics of 126 cases CWI confirmed by computerized tomography(CT) and magnetic resonance imaging(MRI).Results The clinical symptoms and physical signs of CWI lie in the infarction sites and degree. The major clinical types: 27 cases are precortical (21.4%), 31 cases are postcortical (24.6%), 46 cases are subcortical (36.25%). The different type has different appearances of imaging.Conclusion The clinical situation and prognosis in CWI have close correlation with CT and MRI appearances, the promptly examination of CT and MRI can do good to guiding treatment and judging prognosis.
