Abstract

Objective
We investigated the clinical efficacy, advantage and disadvantage of Hakim programmable valve shunt system in hydrocephalus patients. Methods: In a single-center retrospective study, between 2004 and 2008, 31 cases of Hakim programmable valve were implanted at the author's center. The authors analyzed the cause of hydrocephalus, improvement of clinical symptoms, change of Evan's ratio, opening pressure of valve according to disease, number of reprogramming and the reasons of shunt failure. Results: Hakim programmable valve shunt was implanted in 31 cases with 26 hydrocephalus patients. Reoperation was required in 5 patients due to shunt related complications: ventricular cathter obstruction (1 case), valve malfunction (3 cases), infection of peritoneal catheter (1 case). The mean final opening pressure was 83.2 mmH2O, and 82.2 mmH2O, especially in the cases with subarachnoid hemorrhage. The average number of reprogramming in the Hakim programmable valve was 1.81. The Evan's ratio decreased in 21 cases out of 31(67.74%). Decreased mentality and dementia symptom improved in 23 cases out of 30 (76.67%), gait disturbance improved in 18 cases out of 28 (64.29%) and incontinence improved in 18 cases out of 28 (64.29%) Conclusion: In this study, we found that the Hakim programmable valve is effective system in various cases of hydrocephalus and useful for the decrease of reoperation related with overdrainge or underdrainage.
