CT血管成像对ACI患者颈动脉狭窄程度及侧支循环的价值研究

The Value of CT Angiography on Carotid Stenosis and Collateral Circulation in Patients with ACI

目的分析、探究CT血管成像技术在ACI患者颈动脉狭窄、侧支循环等病情诊断方面的成效。方法对我院2021.3-2022.3月期间收治的100例急性脑梗死(ACI)患者一般病理资料进行回顾性分析,以数字减影血管造影(DSA)结果为诊断金标准,对CT血管成像技术(CTA)的诊断价值进行分析,以临床出具的数字减影血管造影(DSA)结果为金标准,分析CT血管成像技术(CTA)在临床上的诊断价值,评估此技术在临床诊断中的效能。结果与临床金标准相比,CTA诊断技术具有较高的临床评估价值[Kappa>0.8~1.0,曲线下面积(AUC)>0.9,P<0.01];CTA诊断技术在评估颈动脉狭窄程度等方面与临床金标准具有一定的一致性[Kappa>0.6~0.8,曲线下面积(AUC)>0.7~0.9,P<0.01];而在评估侧支循环临床诊断中,CTA诊断技术与临床金标准具有一致性,具有较高的评估价值[Kappa>0.8~1.0,曲线下面积(AUC)>0.9,P<0.01]。结论以临床“金标准”的诊断结果为依据分析,CTA诊断技术能够对ACI患者出现病变的血管形态及侧支循环状态等进行全面的评估,CTA诊断结果可为治疗工作提供准确性相对较高且客观的医学依据,确实是评估ACI患者颈动脉狭窄程度、侧支循环状态的可靠办法;而与DSA技术相比,CTA与之具有较高的一致性,说明在病情发作早期为ACI患者实施CTA检查可获悉颈动脉的狭窄及侧支循环状态,有利于改善患者群体的预后。

Objective To analyze and explore effectiveness of CT vascular imaging technology in the diagnosis of carotid artery stenosis,collateral circulation,and otherconditions in ACI patients.Methods A retrospective analysis was conducted on the general pathological data of 100 patients with acute cerebral infarction(ACI)admitted to our hospital from March 2021 to March 2022.The diagnostic value of CT angiography(CTA)was analyzed using the results of digital subtraction angiography(DSA)as the gold standard,and the clinical diagnostic value of CT angiography(CTA)was analyzed using the results of digital subtraction angiography(DSA)as the gold standard,Evaluate the effectiveness of this technology in clinical diagnosis.Results Compared with the clinical gold standard,CTA diagnostic technology has high clinical evaluation value[Kappa>0.8~1.0,Area under curve(AUC)>0.9,P<0.01];CTA diagnostic technology has certain consistency with the clinical gold standard in assessing the degree of carotid stenosis[Kappa>0.6~0.8,Area under curve(AUC)>0.7~0.9,P<0.01];In evaluating the clinical diagnosis of collateral circulation,CTA diagnostic technology is consistent with the clinical gold standard,It has high appraisal value[Kappa>0.8~1.0,Area under curve(AUC)>0.9,P<0.01].Conclusion Based on the clinical"gold standard"diagnosis results,CTA diagnostic technology can comprehensively evaluate the vascular morphology and collateral circulation status of ACI patients,CTA diagnosis results can provide relatively high accuracy and objective medical basis for treatment,It is indeed a reliable method to evaluate the degree of carotid stenosis and collateral circulation in ACI patients;Compared with DSA technology,CTA is highly consistent with it,It shows that the carotid stenosis and collateral circulation status can be learned by CTA examination for ACI patients at the early stage of the disease attack,It is helpful to improve the prognosis of patients.
