Object : Post-traumatic hydrocephalus (PTH) is considered a frequent complication after severe head injury (HI). There is little known about outcome following shunt implantation. Methods : A hospital-based retrospective cross-over study investigated the outcome of 48 patients after severe HI, who had undergone ventricular shunt implantation due to PTH (40 males, mean age at injury 36 years, mean duration from HI to shunt implantation 27 weeks). Telephone interviews with the patients or with caring family members by means of a detailed questionnaire were performed after a mean observation period of 3.3 years after shunt implantation. Outcome was categorized using the Glasgow Outcome Scale (GOS): I: 12 patients, II: 7, III: 16, IV: 9, V: 4 at follow-up. Conclusions : 52.1% had a clear-cut benefit from shunt implantation, whereas 47.9% had not. Posttraumatic seizures were observed in 31 of 48 patients. Other complications after shunt implantation occurred in 20 patients. Revision of shunt implantation was performed in 15 patients (nine due to technical failure, three haemorrhage, one delayed primary wound closure, and two unknown). Two patients clearly deteriorated after operation (one severe frontal bleeding, one sepsis). The best predictive parameter for outcome after shunt implantation was the pre-operative status, patients in a better clinical condition (pre-operative GOS score 3-severe disabled vs 4-persistent vegetative state) had a better outcome. Patient's age at injury did not seem to influence the outcome. Clinical and computertomographic findings were of rather moderate predictive value as regards short- and long-term outcome after shunt implantation. Cisternography does not seem to be of additional help in the establishment of definite diagnosis of PTH.
