Objective      To summarize our experience and assess the clinical value of the programmable shunt valve in treatment of hydrocephalus in children.       Methods      A total of 24 children (at age of 8 months to 11.2 years old

and mean age of 5.7 years old) with hydrocephalus who underwent Ventriculo-peritoneal (V-P) shunt surgery and programmable valve implantation during operation were retrospectively analyzed. The opening pressure was settled based on intraoperative intraventricular pressure

clinical manifestation and imaging results. Postoperative regulator opening pressure was adjusted according to clinical improvement and imaging results after operation.       Results      After operation

adjusting valve pressure was performed for 0 to 4 times

mean 2.6 times. All the cases were followed up for 3 to 28 months

and their clinical symptoms were relieved or disappeared. CT examination showed size of ventricle was reduced compared with preoperative in all cases. Postoperative infection was found in 2 cases

and shunt obstruction in 1 case.       Conclusion      Programmable shunt valve has the advantages of individual pressure setting

and effectively preventing excessive and insufficient segregation postoperatively.
