脑分水岭梗死64层螺旋CT头颈血管成像研究

Study of 64-slice spiral CT carotid and cerebral angiography in patients with cerebral watershed infarction

目的探讨颈内动脉狭窄与脑分水岭梗死的相关性。方法对确诊为脑分水岭梗死22例患者(A组)和普通型脑梗死20例患者(B组)进行64层螺旋CT头颈血管造影成像,并对所得资料进行统计学分析。结果 A组患者颈内动脉狭窄检出率明显高于B组(P<0.05);而2组脑血管异常检出率相比差异无统计学意义(P>0.05)。结论脑分水岭梗死与颈内动脉严重狭窄明显相关,64层螺旋CT头颈血管造影成像是一种安全、无创、简便的颈部和脑血管病变的检查方法,可作为脑分水岭梗死者颈和脑血管病变筛查和评估的首选技术。

Objective To observe the relationship between stenosis of internal carotid artery and cerebral watershed infarction（CWSI）.Methods 64-slice spiral CT carotid and cerebral angiography of 22 patients with CWSI（group A） and 20 patients with common infarction of brain（group B） were analyzed carefully.The data were calculated with SPSS statistic software.Results The detectable rate of stenosis of internal carotid artery were significantly different between group A and B（P〈0.05）,the value in group A was significantly higher than that of group B.The abnormal rate of cerebral was not significantly different between group A and B（P〉0.05）.Conclusion There is a close relationship between CWSI and severe stenosis of internal carotid artery.64-slice spiral CT angiography is a safe,quick and noninvasive method in the diagnosis of carotid and cerebrovascular disease,it may be proposed as a first choice for screening and assessment of carotid and cerebrovascular in patients with CWSI.
