摘要

目的分析急性缺血性脑卒中患者行头颈部CT血管造影(CT angiography,CTA)对病症的早期诊断价值以及准确度.方法选取2020年2月—2023年9月睢宁县人民医院收治的77例疑似急性缺血性脑卒中患者为研究对象,对患者行CT平扫、头颈部CTA,以临床诊断结果作为参考金标准,对比不同检查方法的诊断结果.结果 77例疑似急性缺血性脑卒中患者临床诊断确诊75例.CT平扫诊断检出阳性69例,阴性8例;头颈部CTA诊断阳性75例,阴性2例.头颈部CTA准确度[97.40%(75/77)]与灵敏度[98.67%(74/75)]高于CT平扫[89.61%(69/77)]、90.67%(68/75)],差异有统计学意义(χ2=5.240、6.470,P均＜0.05).CTA与CT平扫的特异度比较,差异无统计学意义(P＞0.05).头颈部CTA诊断显示轻度狭窄21例、中度狭窄28例、重度狭窄25例,诊断符合率98.67%,CT平扫诊断显示轻度狭窄19例、中度狭窄26例、重度狭窄23例,诊断符合率90.67%,两者比较,差异有统计学意义(χ2=6.470,P=0.011).结论颈部CTA用于急性缺血性脑卒中早期诊断价值明显,准确度良好,可以减少诊断过程中不良因素产生的干扰,及时获取精准的信息,为患者病症确诊提供参考.

Abstract

Objective To analyze the value of head and neck CT angiography(CTA)for early diagnosis of acute ischemic stroke patients and the accuracy of this diagnostic method.Methods Seventy-seven patients with suspected acute ischemic stroke admitted to Suining County People's Hospital from February 2020 to Sep-tember 2023 were selected as the study subjects,and CT scanning and head and neck CTA were carried out on the patients,and the clinical diagnosis results were used as the gold standard for reference,and the diagnostic results of the different examination methods were compared.Results Seventy-seven patients with suspected acute ischemic stroke were diagnosed clinically in 75 cases,69 cases were detected positively and 8 cases were detected negatively in CT scanning diagnosis,and 75 cases were diagnosed positively and 2 cases were detected negatively in head and neck CTA diagnosis.The accuracy[97.40%(75/77)]and sensitivity[98.67%(74/75)]of head and neck CTA were higher than that of CT scanning[89.61%(69/77),90.67%(68/75)],and the differences were statistically significant(χ2=5.240,6.470,both P＜0.05).The specificity of CTA and CT scanning was com-pared,and the difference was statistically significant(P＞0.05).The diagnosis of head and neck CTA showed mild stenosis in 21 cases,moderate stenosis in 28 cases,and severe stenosis in 25 cases,with a diagnostic com-pliance rate of 98.67%,and the diagnosis of CT scanning showed mild stenosis in 19 cases,moderate stenosis in 26 cases,and severe stenosis in 23 cases,with a diagnostic compliance rate of 90.67%,compared between the two groups,and the difference was statistically significant(χ2=6.470,P=0.011).Conclusion The value of neck CTA in the early diagnosis of acute ischemic stroke is obvious,with good accuracy,can reduce the interference generated by adverse factors in the diagnostic process,timely access to accurate information,and provide refer-ence for the diagnosis of patient's disease.
