脑分水岭梗死与脑血管狭窄类型相关性研究

目的针对脑分水岭梗死（CWI）与脑血管狭窄类型的相关性进行统计分析。方法对我院从2005年3月至2010年9月收治的128例脑分水岭梗死病患与同期收治的128例非脑分水岭梗死病患行头颅CT和核磁共振MRI检查，并应用头颅多普勒（TCD）检测颅内血管与脑血管造影DSA显示脑血管，统计分析影像结果。结果128例脑分水岭梗死病患与颈内动脉与脑内动脉狭窄有一定的相关性（P〈0．05），其中大脑前动脉狭窄42例（32．8％），大脑中动脉狭窄78例（60．9％），大脑后动脉狭窄36例（28．1％），大脑基底动脉狭窄49例（38．3％），颈内动脉狭窄85例（66．4％），差异有统计学意义（P〈0．05）。结论脑分水岭梗死与颈内动脉和脑内动脉狭窄有一定的相关性，其中，与颈内动脉和大脑中动脉狭窄关系密切，值得深入研究和讨论。

Relationship between cerebral watershed infarction and cerebral vessels

Abstract ] Objective To analyze the relationship between cerebral watershed infarction （ CWI ） and the types ofstenosis of cerebral vessels. Methods 128 patients with CWI and 128 patients with other types of cerebral infarction who had been hospitalized during the period of March 2005 to September 2010 were detected by cranial CT and MRI. TCD and DSA were used to examine cerebral vessels. The imaging findings were analyzed. Results In 128 patients, cerebral watershed infarction was related with internal carotid artery stenosis and internal cerebral arteriostenosis （ P〈 0.05 ）. 42（ 32.8% ）patients were stenosis of precerebral artery stenosis, 78（ 60.9% ） were stenosis of middle cerebral artery, 36 （ 28.1% ） were stenosis of postcerebral artery, 49（ 38.3% ） were basilar artery stenosis, and 85（ 66.4% ） were internal cerebral arteriostenosis, with statistical differences（ P〈 0.05 ）. Conclusions Cerebral watershed in- farction has certain relationship with internal carotid artery stenosis and internal cerebral arteriostenosis, especially with internal carotid artery stenosis and middle cerebral artery stenosis. It is worth further studying and discussing.
