颈动脉多排螺旋CT血管造影成像检查与脑梗塞的临床分析

The Carotid Artery Lines up MSCTA and the Clinical Analysis that Cerebral Infarction

目的 :通过颈动脉多排螺旋CT血管造影成像 (multislicespiralconputedtomographyangiography ,MSCTA)检查探讨颈动脉病变与脑梗塞的关系 .方法 :87例脑梗塞患者作颈动脉MSCTA检查 ,了解颈动脉情况 ,采用非参数检验中的秩相关分析明确颈动脉狭窄程度与脑梗塞严重程度的关系 .结果 :87例颈动脉MSCTA检查 ,4 9例患者有异常血管 ,双侧血管异常 2 0例 ,单侧血管异常 2 9例 .狭窄血管 34支 ,轻度狭窄15支 ,中度狭窄 13支 ,重度狭窄 6支 ,颈内动脉闭塞 8支 . 2 7支血管壁有不同程度的钙化 ,35支颈动脉可以观察到软斑块 .经统计学分析 ,MSCTA检查颈动脉狭窄程度与脑梗塞严重程度存在正相关 ,MSCTA定量诊断颈动脉狭窄程度越高 ,临床诊断脑梗塞的严重程度也越高 .结论 :颈动脉MSCTA检查可以观察颈内动脉的血管形态 ,了解颈动脉狭窄程度及闭塞情况 ,而且可以观察到管壁的钙化及软斑块 。

Objective: By means of examination of MSCTA , to explore the relationship between carotid artery pathological changes and cerebral infarction. Methods: MSCTA examination of carotid artery was carried out in 87 patients with cerebral infarction to understand the pathological changes of carotid artery. By nonparametric statistics (rank correlation) to cognize the relationship between narrow degree of carotid artery and serious degree of cerebral infarction. Results:In 87 MSCTA cases, 49 cases of arteries abnormal, in which 20 cases double side artery abnormal and 29 cases one side artery abnormal. There were 34 branches of arteries narrow, in which 15 slight narrow , 13 medium narrow and 6 serious narrow. There are 8 branches of carotid artery occlusive. 27 branches with different degree calcification. 35 branches with soft spots .The degree of artery narrow and the degree of cerebral infarction showed positive correlation. The higher the degree of narrow carotid artery is, the higher the serious degree of cerebral infarction is. Conclusion: By MSCTA, the changes of carotid artery, narrow degree of carotid artery , out-of-the-way circumstances, mural calcification on tube and soft spots can be observed, which will be helpful for exact diagnosis and therapy of cerebral infarction.
