title: External re-programmation by a new radionuclidic technique of electronic cerebrospinal fluid valve in case of hydrocephalus.
abstract: Hydrocephalus is defined as an abnormal enlargement of the ventricles of the brain due to an excessive accumulation of cerebrospinal fluid (CSF) because of a disturbance of its flow, absorption and/or secretion. The usual method of CSF diversion is a ventriculo-peritoneal shunt. Complications of implanted shunt systems include mechanical failure, shunt pathway obstruction, infection, foreign body (allergic) reaction to implants and CSF leakage along the implanted shunt pathway. These problems are solved with the use of programmable ventricular-peritoneal CSF valves. In this case, we describe a radionuclidic method for the control of successful reprogramming of the CSF valve. Furthermore, we analyze some technical data of such a valve-type are essential for the application of the above technique by nuclear medicine physicians. Scintigraphic evaluation of the electronic V-P drainage valve regulation is a noninvasive, not expensive, rapid and safe method with no complications for the patient and provides a reliable proof of the patency of the V-P shunt.
