OBJECTIVES
The value of transcranial Doppler (TCD) ultrasonography in assessing patients with Idiopathic Intracranial Hypertension (IIH) is uncertain. We sought to determine the contribution of TCD to their evaluation.
MATERIALS AND METHODS
Twenty-three patients with suspected IIH underwent TCD. Mean blood flow (BFV), peak systolic (PSV) and end-diastolic (EDV) velocities, and pulsatility (PI) and resistance (RI) indexes were obtained in the middle cerebral (MCA) and vertebral (VA) arteries and compared (Student's t-test) between patients with confirmed IIH and controls. IIH patients and controls were comparable in terms of age, gender and weight.
RESULTS
The mean +/- SD BFV(MCA), PSV(MCA), EDV(MCA) and PI(VA) in the 13 IIH patients were higher than in the ten controls (59 +/- 6.8, 94 +/- 28.5, 43 +/- 12.4, 0.86 +/- 0.16 and 50 +/- 8.6, 72 +/- 25.8, 32 +/- 11.5, 0.58 +/- 0.45 respectively, P < 0.05) but still within normal values. The mean +/- SD PI(MCA), RI(MCA) and RI(VA) values in the IIH patients and controls were similar.
CONCLUSIONS
TCD parameters had no useful unique features for monitoring IIH patients.
目的
经颅多普勒（TCD）超声检查在评估特发性颅内高压（IIH）患者中的价值尚不确定。我们试图确定TCD在其评估中的作用。
材料与方法
23例疑似IIH患者接受了TCD检查。获取大脑中动脉（MCA）和椎动脉（VA）的平均血流（BFV）、收缩期峰值（PSV）和舒张末期（EDV）速度，以及搏动性（PI）和阻力（RI）指数，并在确诊的IIH患者和对照组之间进行比较（学生t检验）。IIH患者和对照组在年龄、性别和体重方面具有可比性。
结果
13例IIH患者的平均±标准差BFV（MCA）、PSV（MCA）、EDV（MCA）和PI（VA）高于10例对照组（分别为59±6.8、94±28.5、43±12.4、0.86±0.16和50±8.6、72±25.8、32±11.5、0.58±0.45，P<0.05），但仍在正常范围内。IIH患者和对照组的平均±标准差PI（MCA）、RI（MCA）和RI（VA）值相似。
结论
TCD参数对监测IIH患者没有有用的独特特征。
