磁共振血管成像、颈动脉超声对颈内动脉系统急性脑梗死病因学方面的诊断价值

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.

A study of magnetic resonance angiography (MRA)and carotid color doppler ultrasonography on the etiology of acute ischemic stroke

Objective To evaluate the value of magnetic resonance angiography （MRA）and carotid color Doppler uhrasonography on the etiology of acute ischemic stroke. Methods 62 cases with acute ischemic stroke were collected. All the patient underwent MRA and carotid color Doppler uhrasonography. Results ① carotid color Doppler uhrasonography displayed that 56 case （90%） existed vascular pathological change. Including atherosclerosis plagues being fonned（30case,48% ） and vascular steuosis（26case,42% ） in cranial artery . ②46cases（74%） had cerebral artery stenosis underwent MRA. Conclusion The most common cause of acute ischemic stroke was carotid atherosclerosis and stenosis. So it was importantly significant to evaluate the condition of cerebral arteries.
