应用彩色多普勒超声初步探讨脑梗塞与颈动脉粥样硬化病变的关系

目的 初步探讨脑梗塞与颈动脉粥样硬化病变的关系及特点。方法 应用彩色多普勒超声诊断仪，对120例脑梗塞和TIA患者进行颈动脉检测。结果 发现94例颈动脉有不同程度的粥样硬化斑块形成，发生率78％。CT或MRI检查的脑梗塞灶与超声发现颈动脉斑块的侧向基本是一致的。颈动脉粥样硬化斑块多发生于分叉处，软斑与溃疡斑是脑梗塞的主要的栓子来源，血流动力学各项参数及频普形态亦有改变。结论 颈动脉粥样硬化与脑梗塞有密切相关性，超声检测预测脑梗塞的发生对临床预防脑梗塞及治疗提供客观依据。

Primary Exploration of the Relation with Cerebral Infarction and Carotid Atherosclerosis by Color Doppler Ultrasonography

Objective To explore the relation between the cerebral infarction and carotid atherosclerosis. Methods The carotids in one hundred and twenty patients with cerebral infarction were examined by color Doppler ultrasonography. Results The carotid arteriosclerosis and the cerebral infarction proved by CT or MRI were on the same side, both being on the left or on the right side of the head, the positive rate of atheromas was 78%, and one of the major source of thrombus was the soft atheroma and ulcerated atheroma. Parameters of the hemodynamics were also changed. Conclusion There were close relations between carotid arteriosclerosis and the cerebral infarction. Color Doppler ultrasonography can forecast the coming of cerebral infarction and bring objective data for cerebral infarction's prevention and treatment.
