为了明确脑脊液引流途径与特发性常压脑积水（iNPH）发展之间的关系，我们在Valsalva操作期间使用空气对比超声静脉造影检查了20例iNPH患者和13例对照患者的颈内静脉流动模式。iNPH组颈静脉逆行流动频率（19/20,95%）显著高于对照组（3/13,23%）（chi(2)检验，p < 0.001）。我们的研究结果表明，颈静脉逆行流动可能与iNPH的发展有关；因此，分析颈静脉逆行血流可作为诊断iNPH的有用因素。
To clarify the relation between the drainage pathway of cerebrospinal fluid and the development of idiopathic normal pressure hydrocephalus (iNPH), we examined flow patterns of internal jugular veins in 20 patients with iNPH and 13 control patients using air-contrast ultrasound venography during the Valsalva maneuver. The iNPH group had a significantly greater frequency of retrograde jugular venous flow (19/20, 95%) than the control group (3/13, 23%) (chi(2) test, p < 0.001). Our results suggest that retrograde jugular venous flow may be associated with the development of iNPH; therefore, the analysis of retrograde jugular venous flow could be a useful element in the diagnosis of iNPH.
