目的比较超声和多层螺旋CT血管造影(MSCTA)对脑梗死患者颈动脉斑块的检查一致性及对斑块定位、定性、狭窄程度判定的临床价值。方法对65例脑梗死患者在1周内进行超声和MSCTA检查,分别观察斑块有无、位置、性质及血管狭窄程度,并对其进行统计学分析。结果 65例脑梗死患者经超声和MSCTA检查分别发现了76处和78处颅外颈动脉斑块,两者对于颈动脉粥样硬化斑块的检出率差异无统计学意义。超声和MSCTA对脑梗死患者颅外颈动脉不同性质斑块检出率差异无统计学意义(χ2=4.88,P=0.087);对不同部位斑块检出率的差异无统计学意义(χ2=0.42,P=0.81);对各处斑块不同狭窄程度的检出率差异无统计学意义(χ2=8.044,P=0.06)。结论颈动脉粥样硬化和脑梗死的关系密切,超声、MSC-TA在对动脉粥样硬化的检查中具有互补作用。
Objective To compare the consistency of carotid plaque in patients with cerebral infarction and the clinical value of determining the location, qualitative and stenosis of plaque by using ultrasound and multi-slice spiral CT angiography (MSCTA). Methods Sixty-five patients with cerebral infarction underwent ultrasonography and MSCTA within one week. The plaques were examined for their presence, location, nature, and degree of stenosis. Statistical analysis was performed. Results Sixty-six and 78 extracranial carotid plaques were detected by ultrasound and MSCTA in 65 patients with cerebral infarction. There was no significant difference in the detection rate of carotid atherosclerotic plaque among the 65 patients with cerebral infarction. Ultrasound and MSCTA showed no significant difference in the detection rate of extracranial carotid artery plaque in patients with cerebral infarction (χ2 = 4.88, P = 0.087). There was no significant difference in the detection rate of plaque in different sites (χ2 = 0.42, P = 0.81). There was no significant difference in the detection rate of different stenosis between different plaques (χ2 = 8.044, P = 0.06). Conclusion Carotid atherosclerosis is closely related to cerebral infarction. Ultrasound and MSC-TA have complementary effects on the detection of atherosclerosis.
