[摘要] 目的 探討頸動脈多普勒彩超在頸動脈狹窄或閉塞診斷中的應用價值。方法 方便選擇2015年1—6月該院收治的40例疑似頸動脈狹窄或閉塞的患者為研究對象,均行頸動脈多普勒彩超(CDUS)及數字減影血管造影(DSA)檢查,以DSA檢查結果作為頸動脈狹窄或閉塞診斷的金標準,分析CDUS對頸動脈狹窄或閉塞診斷的敏感度、特異度、符合率。結果 以陰性(正常)與陽性(狹窄或閉塞)作為切分點時,頸動脈CDUS診斷的靈敏度、特異度、診斷符合率分別為93.7%、90.7%、91.9%,與DSA診斷結果的一致性較好(Kappa=0.832)。而從臨床治療的角度考慮,以重度狹窄作為切分點,頸動脈CDUS診斷的靈敏度、特異度、診斷符合率分別為86.1%、89.5%、88.8%,與DSA診斷結果的一致性一般(Kappa=0.701)。結論 頸動脈多普勒彩超對頸動脈狹窄的早期篩查具有重要應用價值。

[Abstract] Objective To investigate the application value of carotid stenosis or occlusion diagnosed with carotid color doppler ultrasound(CDUS). Methods Convenient choice in January to June 2015, our hospital of 40 cases of suspected patients with carotid artery stenosis or occlusion as the research object,they were both given CDUS and digital subtraction angiography(DSA) examination,based on DSA examination results as the diagnostic gold standard,analyzed the sensitivity degree,specific degree and coincidence rate of carotid stenosis or occlusion diagnosed with CDUS. Results With negative(normal) and positive(stenosis or occlusion) as a segmentation point,the sensitivity degree,specific degree and diagnosis coincidence rate of carotid CDUS diagnostic were respectively 93.7%,90.7% and 91.9%,the consistency with the DSA diagnosis was good(Kappa =0.832).But considered from the angle of clinical treatment,based on severe stenosis as a segmentation point,the sensitivity degree,specific degree and diagnosis coincidence rate of carotid CDUS diagnostic were respectively 86.1%,89.5% and 88.8%,the consistency with the DSA diagnosis was general(Kappa=0.701). Conclusion Carotid CDUS has important application value of early screening of the carotid stenosis.

近年來,腦卒中發病率呈逐年上升趨勢,嚴重影響中老年人群的生命健康[1]。已有研究表明,頸動脈粥樣硬化所引起的頸動脈狹窄是腦卒中發生的高度危險因素之一,因此,對頸動脈狹窄進行早期篩查并對其狹窄程度進行早期評估對腦卒中的防治及預后具有重要意義[2]。現結合2015年1—6月該院收治的40例疑似頸動脈狹窄或閉塞的患者為研究對象,以數字減影血管造影(DSA)作為金標準,探討頸動脈多普勒彩超在頸動脈狹窄或閉塞診斷中的應用價值,現報道如下。
