Abstract: Objective: To explore the causes,treatment and prevention of the complications after ventriculoperitoneal shunt.Methods: The surgical procedure,prognosis and complication of 75 patients who had accepted ventriculopefitoneal shunt were retrospectively reviewed.Results: Complete recovery was observed in 43 cases,duct block in 16 cases,infection in 13 cases,excessive shunt in 2 cases and bowel perforation in 1 case.Conclusions: Strict disinfection,aseptic and normative operation,meticulous observation and timely management of the complications in patients having received ventriculopefitoneal shunt are essential in improving the clinical efficacy;it is suggested that patients whose drainage tube are repeatedly blocked resort to ventricle-umbilicus-portal vein shunt.
