摘要
目的探讨交界区脑梗死(cerebral watershed infarctjon,CWI)的病因与临床特征。方法回顾性分析42例CWI患者的临床资料,就其病因、临床表现、影像学特征及治疗,结合文献进行分析。结果双侧CWI 12例,占28.6%,皮层前型3例,皮层后型4例,皮层下型5例,主要病因为低血压、低血容量;单侧CWI 30例,占71.4%,皮层前型8例,皮层后型10例,皮层下型13例,主要病因为颈动脉狭窄、糖尿病、低血压、血液流变学异常等。结论CWI病因多样,临床表现复杂,诊断依靠影像学,避免低灌注是控制CWI的关键。
Objective To investigate the etiology and characteristics of cerebral watershed infarction. Methods Medical records of 42 cerebral watershed infarction （CWF） patients,including pathogenesis,clinical manifestation and findings of neuroimaging,as well as the therapy are discussed in comparison with the literatures. Results Among all the patients, 12 cases of bilateral CWI take up 28. 6%, 3 cases are precortieal,5 cases are subeortieal and 4 cases are post-cortical. The main causes are hypotension, hypovolemia. In 30 cases of unilateral CWI （71.4 % ）, 8 cases are pre-cortical, 13 cases are post-cortical and 9 cases are sub-cortical. The main causes are carotid artery stenosis, diabetes, hypotention and abnomal blood rheology. Conclusions The cases of CWI have different causes which led to hypotension. The manifestation of CWI is complicated,The diagnosis of that mainly depends on the findings of neuroimaging. Avoiding low cerebral blood flow is important for prevention of CWI.
