摘要
目的 评价颈动脉狭窄无创性影像学检查方法的临床应用价值 ,探讨颈动脉狭窄与缺血性脑血管病之间的联系。 材料与方法 对 15例 30支颈动脉行多普勒超声 (DUS)、磁共振血管造影 (MRA)及头部 CT& MRI检查。其中 5例同时行颈动脉 CT血管造影 (CTA) ,4例与 DSA对照 ,6例颈动脉重度狭窄者行颈动脉内膜切除术。 结果 15例 30支颈动脉 :轻度狭窄 (<30 % ) 8支 ,中度狭窄 (30 %～ 6 9% ) 6支 ,重度狭窄 (70 %～ 99% ) 8支 (均为一侧 ) ,闭塞 2支 ,未见狭窄 6支。 8支颈动脉重度狭窄者狭窄侧腔隙性脑梗死 5例 ,狭窄对侧皮层梗死 1例 ,双侧脑梗死 1例 ,未见异常 1例。颈动脉闭塞侧大脑中动脉分布区脑梗死 2例。 CTA显示硬化斑块 3例。 结论 颈动脉狭窄与脑梗死的发生、发展密切相关。 DUS、MRA、CTA结合使用能够在颈动脉狭窄的筛选、诊断。
Purpose To estimate the value of the medical imaging in the evaluation of the extracranial carotid artery stenosis Methods 15 patients, 30 carotid arteries were studied with Doppler ultrasound(DUS), MR angiography(MRA). CT&MRI of the brain was done at the same time . 5 patients were also examined by CT angiography (CTA). The result in 4 patients was compared with images obtained with digital subtraction angiography (DSA). 6 patients with severe stenosis received carotid endarterectomy. Results 30 carotid arteries studied included mild stenosis in 8, moderate in 6, severe in 8, normal in 6 and occlusion in 2. In 8 cases of carotid arteries with severe stenosis, there were more infarction lesions revealed on the ipsilateral narrowing carotid artery. The larger volume of the middle cerebral artery distribution infarction followed the occlusion of the carotid artery on the ipsilateral side in 2. Plaques were well delineated in CTA, and confirmed by operation. Conclusions There was close relationship between the carotid artery stenosis and cerebral infarction. The combined use of DUS, MRA, and CTA played an important role in the screening, diagnosing, and monitoring of the carotid artery stenosis.
