A selected series of 22 adult patients with hydrocephalus were treated by a shunt system incorporating a variable pressure Sophy valve or by ventriculojugular shunting against the direction of blood flow using the El-Shafei system. One patient had insertion of two Sophy valves and an El-Shafei shunt. Patient selection was reserved to those with hydrocephalus thought to be at high risk when shunted with systems containing a conventional unipressure valve. None of the eight patients who had ventriculojugular shunting by the El-Shafei method demonstrated any notable clinical or radiological improvement subsequent to shunt insertion. Of the 16 Sophy devices inserted only seven produced a satisfactory result. The current evaluation of shunt malfunction could be improved by support for a national register.
选择了22例成年脑积水患者，采用包含可变压力Sophy瓣膜的分流系统进行治疗，或使用El-Shafei系统逆血流方向进行脑室-颈静脉分流。1例患者植入了两个Sophy瓣膜和一个El-Shafei分流装置。患者选择仅限于那些被认为在使用传统单压力瓣膜系统分流时处于高风险的脑积水患者。通过El-Shafei方法进行脑室-颈静脉分流的8例患者中，分流术后均未显示出任何显著的临床或影像学改善。在植入的16个Sophy装置中，只有7个取得了满意的结果。支持建立国家登记册有助于改进目前对分流功能障碍的评估。
