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 ,对脑梗塞的病因诊断和治疗有较大的帮助
Objective: To explore the relationship between carotid artery lesions and cerebral infarction by multislice multicopter spiral CT angiography (MSCTA) .Methods: Eighty-seven patients with cerebral infarction were examined by carotid artery MSCTA to understand the carotid artery. The non-parametric test Rank correlation analysis to determine the relationship between the degree of carotid stenosis and the severity of cerebral infarction.Results: 87 cases of carotid MSCTA examination, 49 cases of abnormal blood vessels, bilateral vascular abnormalities in 20 cases, unilateral blood vessel abnormalities in 29 cases , 34 vessels of stenosis, 15 with mild stenosis, 13 with moderate stenosis, 6 with severe stenosis and 8 with occlusion of internal carotid artery.27 There were varying degrees of calcification in vessel wall and 35 soft carotis Block.Statistical analysis, MSCTA examination of carotid stenosis and the severity of cerebral infarction there is a positive correlation, MSCTA quantitative diagnosis of carotid stenosis the higher the severity of the clinical diagnosis of cerebral infarction.Conclusion: Carotid MSCTA examination can Observe the morphology of the internal carotid artery blood vessels to understand the degree of carotid stenosis and occlusion, and can be observed in the calcification of the wall and soft plaque on the brain Etiologic diagnosis and treatment of plugs have more help
