TCD高血流速与颅内血管病变之间的关系及MRA结果分析

目的 探讨TCD高血流速度与颅内动脉血管病变之间的关系，以提高TCD诊断颅内血管病变的准确性。方法 对TCD出现一支以上血管血流明显增高的84例患者与其MRA或SDA结果相比较。结果 84例TCD血流速明显增高其MRA及DSA检查结果有80例发现不同部位不同程度的狭窄或闭塞以及其他脑血管病变。结论 TCD高血流速对诊断颅内大动脉的狭窄或闭塞以及脑血管疾病鉴别是可靠的。

The Relationship between TCD Higher Blood Flow Velocity and Pathology of Internal Cranial Arteries and the Analysis of MRA Results

Purpose To investigate the relationship between the TCD higher blood flow velocity and the pathology of internal cranial arteries,so as to improve the veracity of diagnosing cerebrovasculer diseases by TCD. Methods Comparing the blood flow velocity of 84 patients,whose cerebral blood flow are abnormal higher in one or above vessels detected by TCD,with the results of magnetic resonance angiography (MRA). Results Cerebrovascular stricture,closeness and other diseases are discovered at different parts and to some extent in 80 of above 84 cases according to their detecting results of MRA. Conclusion It is reliable to diagnose stricture,closeness and other diseases of internal cranial large arteries by TCD higher blood folw velocity.
