METHODS: In this retrospective study, we included 81 patients aged 0-17 who were treated at our institution. Demographic data, etiology of the hydrocephalus, type of valve implanted, reason for any revision procedures, any complications and survival time of the ventriculo-peritoneal shunts were detected. Statistical analysis was performed using SPSS. The significance level was set at p ≤ 0.05.
RESULTS: Over a mean study period of 18 years, we analyzed 226 valves subjected to 146 revision operations in 81 patients. The etiology of the hydrocephalus (p = 0.874) and the age of the child at the time of VP shunt implantation (p = 0.308) did not have any impact on the shunt survival time. However, the type of the valve significantly changed the survival time of the shunt (p = 0.030). Pressure differential valves presented a longer survival time than gravitational valves.
CONCLUSIONS: The majority of patients in this study needed at least one replacement of the initial shunt system. Pressure differential valves may be beneficial for the survival time of the shunt system.
方法:在这项回顾性研究中,
