彩色多普勒能量图在烟雾病诊断中的价值

摘要

Objective To study the diagnostic value of CDE in moyamoya disease.Methods The intra-and-extracranial arteries in 17 patients with moyamoya disease and 25 healthy volunteers were studies by CDE.The resistance index(RI),pulsatility index(PI),time-averaged flow velocity(Vm)were examined in arteries,including MCA、MCA、ACA、PCA、CCA、ICA、ECA and TSA.Results ①The diagnosis rate of the occlusion or stenosis in intracranial arteries was 87.25%.②The hemodynamic characteristics of CCA and ICA were high flow velocky and low resistance opposite to that of TSA.③The moyamoya vessels were seaned in 10 of all 17 patients with moyamoya disease by CDE.The diagnosis rate of moyamoya disease was 58.82%.Conclusions CDE technique could image the moyamoya vessels as scattered color dots. So CDE had a higher clinic value in diagnosis of moyamoya disease.%目的 探讨彩色多普勒能量图(CDE)对烟雾病的诊断价值.方法 对17例经DSA确诊的烟雾病患者及25例健康对照者大脑前、中、后动脉(ACA、MCA、PCA)、颈总、颈内、颈外动脉(CCA、ICA、ECA)以及颞浅动脉(TSA)的阻力指数(RI)、搏动指数(PI)及平均血流速度(Vm)进行检测分析.结果 @CDE对颅内血管狭窄及闭塞的正确诊断率为87.25%;②烟雾病患者颅外血管CCA、ICA表现为流速下降,阻力升高,而TSA恰恰相反;③CDE显示10例患者颅底异常血管网,即对58.82%的患者做出烟雾病诊断.结论 CDE可将烟雾血管显示为星星点点的血流信号,在烟雾病的诊断中具有较高的临床应用价值.
