【摘要】：目的评价血管超声技术与脑血管造影诊断颈动脉狭窄的临床应用价值。方法回顾性分析130例缺血性脑血管病患者的颈部血管超声和数字减影血管造影术(DSA)检查结果 ,评价血管超声诊断颈动脉狭窄的价值。颈动脉狭窄率及狭窄程度分级按北美症状性颈动脉内膜剥脱术进行计算。结果 130例患者中,260支颈动脉行2种检查,DSA检查显示63例患者颈动脉狭窄,狭窄血管71支,血管超声检查显示56例患者颈动脉狭窄,狭窄血管70支。以DSA检查结果为金标准,血管超声诊断颈内动脉狭窄的敏感性、特异性和准确性分别为71.88%、94.47%和88.97%。血管超声诊断中、重度颈内动脉狭窄的敏感性、特异性和准确性分别为55.56%、99.20%和97.69%。以DSA诊断结果为标准,血管超声诊断颈总动脉狭窄的敏感性为100%,特异性为97.6%,准确性为97.69%。结论血管超声诊断颈动脉狭窄的敏感性较高,诊断颈总动脉狭窄的敏感性高于颈内动脉,可用于颈动脉狭窄的筛选和随访,但对于血管重度狭窄和闭塞诊断仍欠佳,尚不能取代DSA检查。
[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.
