目的探讨分水岭性脑梗死(CWI)患者的病因与机制。方法回顾性分析60例经MRI及临床证实CWI患者的临床资料。结果60例患者的病因中,颈部动脉硬化伴粥样斑块形成严重狭窄32例,血压不稳定11例,心功能不全、心律失常、房颤6例,严重低血压及低血容量3例,其他还有大量饮酒、高血糖、服用避孕药等。结论颈部动脉硬化伴粥样斑块形成严重狭窄是CWI的主要病因,血压波动幅度过大、心脏疾病也是CWI的重要病因,其他还有高血糖、高血脂、大量饮酒等。
Objective To explore the etiology and mechanism of watershed cerebral infarction (CWI). Methods Retrospective analysis of 60 cases of clinical data confirmed by MRI and clinically confirmed CWI. Results Among the 60 patients, there were 32 cases of atherosclerosis and atherosclerotic plaque with severe stenosis, 11 cases of unstable blood pressure, cardiac insufficiency, arrhythmia, atrial fibrillation in 6 cases, severe hypotension and hypovolemia in 3 cases , There are a lot of other drinking, high blood sugar, taking contraceptives. Conclusion Severe stenosis of atherosclerotic atherosclerosis and atherosclerotic plaque is the main cause of CWI. The fluctuation of blood pressure is too large. Heart disease is also an important cause of CWI. Others include hyperglycemia, hyperlipemia and heavy drinking.
