颈动脉粥样斑块与脑梗塞的关系

The Relationship between Artherosclerotic Plaque in Carotid Artery and Cerebral Thrombosis

目的 :研究颈动脉粥样斑块性状和部位与脑梗塞的关系。材料和方法 :回顾性分析 86例脑梗塞彩色多普勒超声检测颈动脉相关数据。结果 :本组颈动脉粥样斑块发生率为 82 .6%。双侧颈动脉受累及一条血管多个斑块及各型斑块并存多见 ,颈总动脉 (CCA)分叉处发生率最高。高血压合并脑梗塞组舒张末期血流速度 (EVD)较正常人组明显下降 (P<0 .0 5 )。颈动脉IMT及粥样斑块指数与脑梗塞相关因素呈正相关 ,软斑及合并溃疡的混合斑是脑梗塞主要的栓子来源之一。结论 :颈动脉超声能显示动脉粥样斑块的相关物理特性 ,对脑梗塞的疗效观察与预测具有十分重要的意义。

purpose: To study the relationship between location and characteritics of arteriosclerotic plaque and cerebral thrombosis. Materials and Methods: Retrospective study of index of carotid artery by color Doppler ultrasound in 86 cases of cerebral thrombosis. Results: In 82.6% of the cases was plaque found in arthrosclerotic carotid artery . Bilateral carotid artery might be involved at the same time. Multiple plaque in a single artery was not uncommon. The positive finding was more frequently encountered at the bifurcation of common carotid artery. The end disatolic velocity in hypertensive patient with cerebral thrombosis was lower than in normal persons (p<0.05). Positive correlation was present between carotid artery IMT, artherosclotic plaque index and cerebral thrombosis. Conclusion: The soft plaque with or without ulceration was considered more thrombogenic which can be displayed by ultrasound.
