Sampling MethodProbability Sample
Study Population

The study population will consist of asymptomatic PTC research subjects who have a VP shunt with a single ventricular catheter implanted for PTC and are visiting for routine care.

You may qualify if:

  • years old or older Adult men or women who possess a VP shunt placed for PTC;
  • Capable of providing valid signed informed consent, or has a legal guardian, health care agent, or surrogate decision maker (according to local statutes, and collectively referred to as "surrogates" in this protocol) capable of providing valid, signed informed consent;
  • Subjects will be asymptomatic visiting for routine care at 2-4 weeks post op

You may not qualify if:

  • Presence of multiple shunts, or presence of more than one distal shunt catheter (regardless of function) crossing the clavicle ipsilateral to the shunt with suspected obstruction;
  • ShuntCheck test would interfere with standard patient care, or emergency shunt surgery that cannot be delayed is indicated;
  • Presence of an interfering open wound or edema over any portion of the VP shunt.
