RESUMEN
Objective To investigate the outcome after ventriculoperitoneal (V-P)shunt for post-traumatic hydrocephalus (PTH). Methods A retrospective study investigated the outcome of 51 patients after head injury, who had undergone V-P shunt due to PTH.The Glasgow outcome scale (GOS),age and intracerebral pressure(ICP) were analyzed. Results Twenty-two of 33 patients with COS 3 or less than 3 scores had clear-cut benefit from V-P shunt,while only 6 of 18 patients with GOS 4 scores did.Tbe GOS before V-P shunt had correlated with the GOS 6 months after operation. The patients with GOS 3 or less than 3 scores had good outcome than patients with COS 4 scores (P<0.05). Patients' age and ICP before the V-P shunt did not influence the outcome (P>0.05 ). Conclusion V-P shunt has much benefit for the patients with PTH, GOS before operation is a best predictive parameter for outcome after V-P shunt.
