头颈部MSCTA和DSA对颈部动脉血管狭窄性病变的对比分析

目的：对比分析多层螺旋CT头颈部血管造影(MSCTA)、数字血管造影(DSA)对颈部动脉血管狭窄性病变的诊断价值。方法整群选取该院2011年9月—2015年1月所收治198例具有临床症状的患者。入院后分别行颈部动脉血管DSA、MSCTA检查,比较两种检查方法颈部动脉血管狭窄情况,并进一步对DSA、MSCTA结果分别进行Kappa一致性检验。结果在198例患者中运用DSA检查方法,检测到轻度狭窄、中度狭窄、重度狭窄和闭塞所占的比例分别为58.6%、15.7%、14.1%和11.6%。MSCTA检查方法检测到轻度狭窄、中度狭窄、重度狭窄和闭塞所占的比例分别为60.1%、14.6%、13.6%和11.6%。t=1.12,P<0.05。MSCTA与DSA检测符合率高,具有较高的一致性,Kappa值为96.1%,假阴性率为1.01%(2/198),假阳性率为0.5%(1/198)。结论 MSCTA与DSA检查结果一致性较高,MSCTA作为一种无创性检查方法,对颈动脉血管斑块及血管狭窄性病变诊断具有重要价值。

Analysis the Diagnostic Value in Carotid Artery Stenosis Lesions between Multi-slice Computed Tomography Angiography and Digital Angiography

Objective To analysis the diagnostic value of carotid artery stenosis lesions of MSCTAand DSA. Methods Se-lection of our hospital in September 2011 January-2015 treated 198 cases of patients with clinical symptoms. After admis-sion, DSA and MSCTA were performed in the cervical artery, and the carotid artery stenosis was compared between the two methods, and the results of MSCTA and Kappa were tested for DSA consistency.Results 159 cases(29.8%) of carotid artery stenosis were found in the total 198 cases by DSA, and the mild stenosis、moderate stenosis、severe stenosis and occlusion were 58.6%、15.7%、14.1%and 11.6%. 56 cases (28.3%) were found by MSCTA. t=1.12,P<0.05.MSCTA and DSA detection rate with higher consistency, the Kappa value was 96.1%, the false negative rate was 1.01%(2/198), and the false positive rate was 0.5%(1/198). Conclusion MSCTA and DSA results of high consistency, and MSCTA as a non-invasive method has important value in diagnosis of carotid artery plaque and vessel stenosis lesions.
