【摘要】：目的評價血管超聲技術(shù)與腦血管造影診斷頸動脈狹窄的臨床應(yīng)用價值。方法回顧性分析130例缺血性腦血管病患者的頸部血管超聲和數(shù)字減影血管造影術(shù)(DSA)檢查結(jié)果 ,評價血管超聲診斷頸動脈狹窄的價值。頸動脈狹窄率及狹窄程度分級按北美癥狀性頸動脈內(nèi)膜剝脫術(shù)進(jìn)行計算。結(jié)果 130例患者中,260支頸動脈行2種檢查,DSA檢查顯示63例患者頸動脈狹窄,狹窄血管71支,血管超聲檢查顯示56例患者頸動脈狹窄,狹窄血管70支。以DSA檢查結(jié)果為金標(biāo)準(zhǔn),血管超聲診斷頸內(nèi)動脈狹窄的敏感性、特異性和準(zhǔn)確性分別為71.88%、94.47%和88.97%。血管超聲診斷中、重度頸內(nèi)動脈狹窄的敏感性、特異性和準(zhǔn)確性分別為55.56%、99.20%和97.69%。以DSA診斷結(jié)果為標(biāo)準(zhǔn),血管超聲診斷頸總動脈狹窄的敏感性為100%,特異性為97.6%,準(zhǔn)確性為97.69%。結(jié)論血管超聲診斷頸動脈狹窄的敏感性較高,診斷頸總動脈狹窄的敏感性高于頸內(nèi)動脈,可用于頸動脈狹窄的篩選和隨訪,但對于血管重度狹窄和閉塞診斷仍欠佳,尚不能取代DSA檢查。
[Abstract]:Objective to evaluate the clinical value of vascular ultrasound and cerebral angiography in the diagnosis of carotid artery stenosis. Methods the results of (DSA) and digital subtraction angiography in 130 patients with ischemic cerebrovascular disease were retrospectively analyzed to evaluate the value of ultrasound in the diagnosis of carotid artery stenosis. The stenosis rate and grade of carotid stenosis were calculated according to symptomatic carotid endarterectomy in North America. Results among the 130 patients, 2 kinds of carotid arteries were examined. DSA showed 63 cases of carotid artery stenosis, 71 stenosis vessels, 56 cases of carotid artery stenosis and 70 stenosis vessels. The sensitivity, specificity and accuracy of ultrasound in the diagnosis of internal carotid artery stenosis were 71.88%, 94.47% and 88.97%, respectively. According to the gold standard of DSA, the sensitivity, specificity and accuracy were 71.88%, 94.47% and 88.97%. The sensitivity, specificity and accuracy of ultrasound in the diagnosis of severe internal carotid artery stenosis were 55.56%, 99.20% and 97.69%, respectively. According to the diagnostic results of DSA, the sensitivity, specificity and accuracy of ultrasonic diagnosis of common carotid artery stenosis were 100%, 97.6% and 97.69%, respectively. Conclusion Ultrasonography is more sensitive than internal carotid artery in the diagnosis of carotid stenosis. It can be used for screening and follow-up of carotid stenosis, but the diagnosis of severe stenosis and occlusion of carotid artery is still poor. There is no substitute for DSA inspection.
