Proximal shunt obstruction or obstruction of the ventricular catheter may present with signs and symptoms of shunt failure with either no cerebrospinal fluid flow or a falsely low intracranial pressure (ICP) upon shunt tap. The author reports a technique for lowering the ICP and for measuring the pressure in patients with such obstruction by cannulation of the reservoir and ventricular catheter to penetrate into the ventricle with a 3 1/2-in. No. 22 spinal needle. The findings in 20 cases in which this approach was utilized are summarized.
近端分流梗阻或脑室导管梗阻可能表现为分流失败的体征和症状，即分流时无脑脊液流动或颅内压（ICP）假性降低。作者报告了一种通过将储液囊和脑室导管插管，用3.5英寸22号脊髓穿刺针穿透进入脑室来降低颅内压并测量此类梗阻患者压力的技术。总结了采用该方法的20例患者的研究结果。
