摘要
目的探讨首次发病急性脑梗死患者颅外段颈动脉狭窄的超声血管检查（uhrasonography，US）和数字减影血管造影（digital substraction angiography，DSA）检查的一致性。方法32例疑似症状性颅外段颈动脉狭窄的急性脑梗死患者128条颈动脉行US和DSA检查，根据NASCET法对DSA结果测量，分别根据NASCET法和截面积法对US结果测量，以DSA检查结果为金标准，评价32例患者颅外段颈动脉狭窄超声检查结果的敏感性、特异性、准确性。结果根据NASCET法US检查结果的敏感性88．33％、特异性94．59％及准确性89．84％；根据截面积法US检查结果的敏感性为81．48％、特异性93．24％及准确性88．28％。根据NASCET法血管分级中颈动脉狭窄〈50％的敏感性、特异性及准确性分别为58．62％、89．90％及82．81％；Kappa=0．63。结论超声血管检查评价颅外段颈动脉狭窄与DSA一致性较好，适用于人群初选检查，必要时尚需行DSA检查。
Objective To assess the consistency of ultrasonography （US） and digital subtraction angiography （DSA） of extracranial carotid artery stenosis in the first attack of acute cerebral infarction patients. Methods 128 vessels in 32 patients with suspect of symptomatic carotid artery stenosis were evaluated by US and DSA. Stenosis measurement on DSA were evaluated according to NASCET criteria, and stenosis measurement on US according to NASCET criteria and cross section criteria. According to stenosis measurement on DSA for the gold standard, the sensitivity, specificity, accuracy of stenosis measurement on US in 32 patients were evaluated. Results The sensitivity, specificity, accuracy of stenosis measurement on US in 32 patients according to NASCET was 88.33 %, 94.59 % or 89.84% respectively. The sensitivity, specificity, accuracy of stenosis measurement on US according to cross section standard was 81.48%, 93.24% or 88.28 % respectively. The sensitivity, specificity, accuracy of severe stenosis （ 〈 50% ） measurement on US according to NASCET was 58.62%, 89.90% or 82.81% respectively. Conclusion Stenosis measurement on US is consistent with DSA. US is an effective technique to estimate extracranial carotid artery stenosis, and could be used as a screening test for the diagnosis and follow - up examination of the carotid artery stenosis.
