    Abstract:
    Ventriculoperitoneal shunt surgery was developed to manage excessive cerebrospinal fluid (CSF) in the brain's ventricles and is considered a mainstream treatment. Despite the development of the shunt device system, various complications still occur. In this study, we reported 307 cases and a long-term follow-up of at least five years of adult patients who underwent VP shunt surgery and analyzed various factors that may affect revision surgery. A retrospective study was conducted at Asan Medical Center, Korea, a tertiary medical center. We reviewed 307 cases from January 2012 to December 2018. The patients' neurological status, predisposing medical conditions, laboratory findings, and other operation-related factors were reviewed using electrical medical records. The normal function group comprised 272 cases (88.6%), and the overall incidence of revision group comprised 35 cases (11.4%). Of the 35 revision surgery cases, 30 (85.71%) were due to shunt malfunctions, such as obstruction, overdrainage, and valve-related errors while 5 (14.29%) were due to shunt infection. Patient demographics, mental status, and operation time did not influence revision as risk factors. Serum laboratory findings showed no statistical difference between the two groups. The white blood cell (WBC) count in the CSF profile differed significantly between the two groups. The Hakim Programmable valve (Codman, USA) is mainly used in our center. In addition, various shunt systems were used, including Strata Regulatory valve (Medtronic, USA), proGAV (Aesculap, USA), and Accu-Flo (Codman, USA). This study analyzed the factors affecting long-term outcomes. Based on these findings, efforts are needed to achieve more favorable outcomes in the future.
