The Locator Tool must be precisely aligned
with both the valve's direction of flow and the
center of the hard valve mechanism for an
accurate indication reading. Alignment can be
more challenging if tissue thickness is >10 mm
above the valve. In these instances, verify the
valve setting with x-ray or fluoroscopy. See
SECTION C: Troubleshooting and SECTION D:
Confirming the Current Valve Setting.
Adverse Events
Accumulation of biological matter within the
valve can:
•
cause difficulties adjusting the valve setting
with the Tool Kit
•
impair the antireflux function
Adjusting the valve to a performance setting that
is lower than necessary can lead to excessive CSF
drainage, which can cause subdural hematomas,
slit-like ventricles, and in infants, sunken fontanels.
