摘　　要：目的 :探讨颈动脉系统短暂性脑缺血发作 (TIA)颅内血管的病变特点。方法 :采用经颅多谱勒超声 (TCD)对 32例颈动脉系统 TIA患者进行常规检测 ,对 2例经 TCD诊断为颅内血管狭窄患者进行数字减影血管造影 (DSA)。结果 :2 3例(71.9% )患者存在病侧 TCD流速异常 ,12例 (37.5 % )的患者有颅内动脉狭窄 ,2 5例患者有不同程度的频谱图形异常 ,病变血管 PI、RI值增高。结论 :颅内动脉的硬化、狭窄是颈动脉系统 TIA发病的基础。Objective:To understand the characteristics of intra-cranial arterial lesions in patients with carotid TIA.Methods:Routine Transcraninal Doppler(TCD) examinations were performed in 32 patients with carotid TIA , 2 cases were identified as arterial stenosis, which were furthermore confirmed by digital substraction angiography(DSA).Result:The abnormality of TCD was 71.9%, 37.5% cases of the patients were identified as arterial stenosis,while most of the patients showed arteriosclerosis.Conclusion:arteriosclerosis and arterial stenosis is the pathologic basis of carotid TIA.
