头部CTA检查对脑梗死患者脑血管狭窄程度的诊断价值分析

Analysis of the Diagnostic Value of Head CTA on the Degree of Cerebral Vascular Stenosis in Patients with Cerebral Infarction

目的分析头部CTA检查对脑梗死患者脑血管狭窄程度的诊断价值。方法将我院2018年3月至2021年3月共80例脑梗死患者作为研究对象,所有患者大部分接受头部CTA检查与MRA检查,以DSA诊断结果为“金标准”,分析头部CTA检查对脑梗死患者脑血管狭窄程度的诊断价值。结果DSA结果显示,无狭窄9例,占比11.25%;轻度狭窄20例,占比25.00%;中度狭窄31例,占比38.75%;重度狭窄17例,占比21.25%;完全闭塞3例,占比3.75%。CTA诊断结果与DSA相比差异无统计学意义(P>0.05)。MRA诊断结果与DSA相比差异无统计学意义(P>0.05)。CTA敏感性高于MRA,差异具有统计学意义(P<0.05)。两种检查方法特异性差异无统计学意义(P>0.05)。结论头部CTA检查对脑梗死患者脑血管狭窄程度的诊断价值较高,能够有效显示脑梗死患者供血动脉的具体情况,可作为临床首选的检查方式,值得推广应用。

Objective To analyze the diagnostic value of head CTA examination for the degree of cerebral vascular stenosis in patients with cerebral infarction.Methods A total of 80 patients with cerebral infarction in our hospital from March 2018 to March 2021 were studied.All patients received head CTA examination and MRA examination.The DSA diagnosis result was used as the"gold standard"to analyze the head CTA The diagnostic value of examination for the degree of cerebral vascular stenosis in patients with cerebral infarction.Results The results of DSA showed that there were no stenosis in 9 cases,accounting for 11.25%;20 cases of mild stenosis,accounting for 25.00%;31 cases of moderate stenosis,accounting for 38.75%;17 cases of severe stenosis,accounting for 21.25%;complete occlusion 3 cases,accounting for 3.75%.There was no statistically significant difference between the diagnosis results of CTA and DSA(P>0.05).There was no statistically significant difference between the diagnosis results of MRA and DSA(P>0.05).The sensitivity of CTA was higher than that of MRA,and the difference was statistically significant(P<0.05).There was no statistically significant difference in the specificity of the two inspection methods(P>0.05).Conclusion The head CTA examination has a high diagnostic value for the degree of cerebral vascular stenosis in patients with cerebral infarction,and can effectively show the specific conditions of the blood supply arteries in patients with cerebral infarction.It can be used as the first clinical examination method and is worthy of promotion and application.
