ObjectiveThis study assesses the clinical outcome after early combined cranioplasty (own frozen bone) and shunt implantation (Codman-Medos programmable VP shunt) in patients with skull bone defects and cerebrospinal fluid (CSF) circulation disorders.MethodMedical records were reviewed retrospectively for the last 100 patients with CSF disorders after trauma or subarachnoid hemorrhage (SAH), who previously underwent decompressive craniotomy owing to therapy-resistant brain swelling. Patients treated with early (5 to 7 weeks after injury) combined cranioplasty and shunt implantation were analysed and a follow-up for the survivors was obtained.ResultsIn 60 patients with a daily CSF external drainage over 150 ml and dilated ventricles in CT scan, a programmable VP shunt was implanted simultaneously with the cranioplasty within 5.1 weeks after decompression. The neurological condition 6 months later was good (independent patients) in 39 cases (65%); 12 patients (20%) survived with a severe disability; three patients (5%) remained in a persistent vegetative state and only six patients (10%) died. There were few complications: bone or shunt infection (three cases), post-operative intracranial bleeding (one case), transitory neurological impairment after bone reimplantation (two cases), bone resorption (two cases) and shunt dysfunction (three cases).ConclusionThe early reimplantation of the patient's own skull bone combined to the employment of a programmable shunt system allowed us a dynamic adjustment of the intracranial pressure (ICP) changes. The combined treatment reduced the number of required surgical procedures, complications and unsatisfactory patient outcomes.
