摘要
目的探讨多层螺旋CT血管造影(CTA)对缺血性脑血管病患者颈动脉狭窄程度及狭窄部位的诊断价值。方法收集366例在新发颈系脑梗塞并完成头颈部DSA及CTA检查的患者,对比两种检查方法在诊断颈动脉狭窄程度及狭窄部位上的一致性。结果 DSA和CTA检查颈动脉狭窄程度的检查结果,两者差异无统计学意义(P>0.05);对狭窄程度分层比较,轻度狭窄差异有统计学意义(P<0.05);中度狭窄、重度狭窄及完全闭塞时两者比较,差异无统计学意义(P>0.05)。366例患者共检出粥样斑块169块,I型98块;II型45块;Ⅲ型26块。结论 CTA可作为颈部血管狭窄评价及斑块性质检测的检查方法。
Objective To discuss the diagnostic value of using Multi-slice Computed Tomography angiography（CAT） to diagnose the degree of carotid artery stenosis of ischemic cerebrovascular patients.Methods By collecting 366 cases of first-time cerebral infarction which were examined by DSA and CTA.Then the consistency of DSA and CTA were compared to diagnose the degree and location of carotid artery stenosis.Results The results of DSA and CTA for the degree of carotid artery stenosis showed no statistically difference（P〉0.05）,mild stenosis of the 2 groups（DSA group and the CTA group） compared,the results showed statistically significant difference（P〈0.05）,moderate stenosis and severe stenosis of the 2 groups compared,there was no statistically significant difference（P〉0.05）.169 out of the 366 patients were detected to have plaques,97 type Ⅰ plaques,42 type Ⅱ plaques,22 type Ⅲ plaques.Conclusion As an examination method,CTA could evaluate carotid artery stenosis and detect the character of plaques.
