目的探讨磁共振血管成像、颈动脉超声检查对急性颈内动脉系统脑梗死的病因学诊断意义。方法回顾分析62例急性脑梗死患者颈动脉超声与磁共振血管成像检查结果,观察其异常情况。结果①56例(90%)患者颈动脉超声显示血管异常,存在动脉粥样硬化,其中30例(48%)伴有多发斑块形成,26例(42%)伴有管腔狭窄(此56例患者中40例MRA有异常);②46例(74%)患者MRA示脑动脉狭窄。结论颈内动脉粥样硬化斑块和动脉狭窄是急性脑梗死常见原因,因此常规对脑血管状况进行MRA和颈动脉超声检查,对其病因和诊断能做出客观的评价。
Objective To investigate the significance of magnetic resonance angiography and carotid ultrasonography in the etiological diagnosis of acute carotid artery cerebral infarction. Methods A retrospective analysis of 62 cases of acute cerebral infarction in patients with carotid ultrasound and magnetic resonance imaging findings and observe the abnormal situation. Results Fifty-six patients (90%) had carotid artery ultrasonography which showed vascular abnormalities and atherosclerosis. Thirty (48%) patients developed multiple plaques and 26 (42%) patients had lumen stenosis 40 patients had abnormal MRA); ② MRA showed cerebral artery stenosis in 46 patients (74%). Conclusion Internal carotid artery atherosclerosis plaque and arterial stenosis are common causes of acute cerebral infarction. MRA and carotid ultrasonography were routinely performed on cerebrovascular diseases, and their etiology and diagnosis can be objectively evaluated.
