目的对数字减影血管造影术(DSA)和三维CT血管造影(CTA)在诊断头颈部血管疾病中的价值进行分析和探讨。方法选择130例头颈部血管病患者作为研究对象,分别采用头颈部血管DSA、CTA这两种方式对患者进行检查,比较两种检查结果。结果分析和比较头颈部血管DSA、CTA这两种方式,发现CTA检查全部为大脑动脉或颈动脉血管狭窄,而采用DSA检查有128例大脑动脉或颈动脉血管狭窄,其中有2例误诊,具有98.4%的符合率,通过Kappa一致性检验,结果为K=0.9098,具有较高的一致性,差异具有统计学意义(P<0.05);有198支血管经过CTA检查显示异常,经过DSA检查有193支显示异常,具有97.5%的符合率,通过Kappa一致性检验,结果为K=0.8.141,具有较高的一致性,差异具有统计学意义(P<0.05)。结论 DSA与CTA这两种检查方式的临床价值均较高,其中CTA具有方便、快捷以及相对无创的特点,因此可以将其作为首选的诊断头颈部血管病的方法 ,而DSA具有较高的准确性,可以将其看作是治疗前的诊断方法。
Objective To analyze and discuss the value of digital subtraction angiography (DSA) and three-dimensional computed tomography (CTA) in the diagnosis of head and neck vascular diseases. Methods A total of 130 patients with head and neck vascular disease were selected as study subjects. Two methods, DSA and CTA, were used respectively to examine the patients and compare the two results. Results Both DSA and CTA of head and neck blood vessels were analyzed and compared. CTA examination was found to be cerebral artery or carotid artery stenosis. However, there were 128 cases of cerebral artery or carotid artery stenosis by DSA, of which 2 were misdiagnosed, With a coincidence rate of 98.4%. The result of Kappa consistency test showed that K = 0.9098, with a high consistency, the difference was statistically significant (P <0.05); 198 vessels showed abnormalities after CTA examination, after DSA examination 193 showed abnormalities, with 97.5% compliance rate, by Kappa consistency test, the result was K = 0.8.141, with a high consistency, the difference was statistically significant (P <0.05). Conclusions DSA and CTA have higher clinical value in both examinations. Among them, CTA is a convenient, rapid and relatively noninvasive method, so it can be used as the preferred method to diagnose head and neck vascular disease. However, DSA has higher Accuracy, you can think of it as a pre-treatment diagnosis.
