Abstract:
OBJECTIVE: The goal of this study is to assess the safety and efficacy of the Codman Hakim programmable valve versus differential pressure valve in the treatment of patients with hydrocephalus. METHODS: The authors conducted a retrospective study of 83 patients who were implanted the Codmam Hakim programmable valve and differential pressure valve between January 1996 and April 2001. We analyzed complications, the number of shunt revision, and prognosis between the two groups. We analyzed initial pressure setting, the cause of reprogramming, and the number of reprogramming in Codman Hakim programmable valve. RESULTS: No statistically significant difference was apparent between the Codmam Hakim programmable valve group and a differential pressure valve group in complications, primary disease entities in shunt revision cases and prognosis(p>0.05). And statistically difference was not apparent in the number of shunt revision(p=0.07). The average pressure and range of initial pressure setting in the Codmam Hakim programmable valve was 97.1mmH2O and 50~150mmH2O, respectively. The number of cases of reprogragmming in the Codmam Hakim programmable valve was 12 in total, 1 time in 9 cases , 2 times in 2 cases, and 3 times in 1case. CONCLUSION: The Codmam Hakim programmable valve can decrease shunt revision caused by underdrainage and overdrainage complications. The optimal pressure settting is the key point to decreasing reprogramming and complications in the Codmam Hakim programmable valve and a differential pressure valve.
