Official title

Inadvertent Cerebral Spinal Fluid Valve Reprogramming: Prevalence and the Correlation With Signs, Symptoms, Radiographic Changes and the Exposure to Magnetic Fields.

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The treatment of hydrocephalus is the most time consuming, and arguably the most important role of the pediatric neurosurgical service at most children's' hospitals. Despite many technological advances, cerebral spinal fluid (CSF) shunting procedures remain the mainstay of hydrocephalus treatment. While often lifesaving, CSF shunting procedures are associated with high complication rates and account for a disproportionate share of health care expenditures and morbidity. Programmable CSF shunt valves, through which CSF flow and pressure can be adjusted by quick and painless transcutaneous reprogramming, have been implanted for more than 15 years in the developed world. Reprogramming these valves relies on rotational magnetic forces, which are applied by neurosurgeons and neurosurgical advanced practice providers. Inadvertent reprogramming (IR) can occur when patients with these valves are exposed to magnetic fields in the environment, which may lead to serious symptoms that may require urgent reprogramming and/or surgery. The concurrent proliferation of magnetically sensitive programmable CSF shunt valves and household items that generate substantial magnetic fields has caused concern among patients, parents and providers about the potential consequences of inadvertent valve reprogramming. This growing concern led the FDA to issue a warning to individuals with programmable valves in 2014, which deemed the programmable valves safe for use but vulnerable to IR when household devices such as tablets or cell phones are placed within 2 inches of the valve. The FDA recommended further study, stating that no systematic evaluation had been performed regarding the prevalence of accidental valve adjustments. By evaluating each of the patients with magnetically susceptible CSF shunt valves, during each of the routine points of contact with the service, investigators aim to define the prevalence of inadvertent shunt reprogramming, to correlate with the presence and absence of symptoms and radiographic changes, and to evaluate the risk of inadvertent shunt reprogramming based on exposure to common environmental items.
