Codman Programmable Shunt
Why is the codman hakim programmable vp shunt setting range so large? (30 to 200 mmh2o) what do the settings mean, and what's the average pressure?
Easy setting changes: The pressure settings can be viewed as a measure of how much fluid is allowed to drain through the shunt. The lower the pressure setting, the more fluid can drain through the system. A typical setting is between 110-130 but treating hydrocephalus is not always a "one size fits all" for every patient. Some individuals have side effects at certain settings and need a 'different pressure setting'. ...Read moreSee 1 more doctor answer
Depends on pressure: The valve setting refers to a pressure value, rather than volume of csf. A setting of 140 means that the valve opens and begins draining when the pressure reaches 140 mmhg, and below that level the valve remains closed. Therefore the amount of CSF drained depends on how much time the pressure remained over the opening pressure. This may be 0 to 100%. ...Read moreSee 1 more doctor answer
What's the chance (percentage) that an MRI will change the settings on a codman hakim programmable vp shunt? Can anything else change it?
High: The codman hakin programmable vp shunt does not have the newer "locks" like the codman certas or the sophysa that prevent changes in a high magnetic field like an mri. In fact, neurosurgeons are trained to be prepared to re-program the vp shunt any time the patient has an MRI scan. Any time these shunts are near a high magnetic field, there is a risk that the shunt will change its setting. ...Read moreSee 2 more doctor answers
Can I go thought airport security a fly from az to Spain with a programmable shunt without a problem?
What's are the difference between the three available programmable shunts commonly used to treat hydrocephalus?
Several differences exist. One the number of pressure settings, available to program, another is the ability to tolerate exposure to mri. Finally, the ability to 'virtually shut the device off' by using a high pressure setting is another feature present that may or may not be present in a given device.

I have hydrocephalus since birth. I have a programmable shunt. Over a couple of days I am now getting neck pain. Is this normal?
Hard to say.: Neck pain has lots of causes, major and minor. With a shunt, you have to be cautious, though. If you have never had neck pain like this before, or if you have fever, dizziness, or anything else unusual, give your doc a call for advice and treatment options or go to the ER. Your doc will get more details than you can give here, and will guide you best. ...Read more
Age 27 yrs with hydrocephalus had III ventriculostomy 17 yrs ago and then had a programmable shunt 8 yrs ago, decompression surgery 5 yrs. Ok to fly?
Relieves csf: A shunt diverts CSF that is accumulating in the spaces of the brain called ventricles to the abdominal space. Normally the CSF which is produced in the ventricles exists through small pores in the ventricles to circulate the brain and down the spinal cord. If those pores are blocked or the CSF can not drain to the spinal cord, then it accumulates in the ventricles and decrease brain tissue. ...Read moreSee 1 more doctor answer
Possible: It is possible for the hydrocephaly to slowly resolve and not re-occur. It certainly depends what caused the hydrocephaly in the first place. It is more common to slowly resolve if it was caused by a blled in the brain when the baby was premature. Less likely if the cuase is a physical restriction of the flow of CSF as in dandy-walker cyst or arnold chiari defect. ...Read moreSee 1 more doctor answer
It depends...: I assume you are talking about CSF flow. Usually, this is treated by a catheter that is placed in the ventricle of the brain, then tunneled under the skin to the abdominal cavity where the fluid is resorbed. This is a vp shunt or ventriculoperitoneal shunt. There are other less common shunts, to treat hydrocephalus. ...Read more
Radiologic eval: In order to evaluate your shunt, the neurosurgeon would do a physical exam and then a head CT. They often look to see if the ventricles are completely collapsed. Too little CSF around the brain can cause problems too. Make an appointment to see your neurosurgeon and ask. ...Read more
Common procedure: While untoward outcomes may occur with any surgery, shunt placement is one of the most commonly performed neurosurgical procedures. The surgery entails passing a tube or catheter into the brain. Another catheter is passed under the scalp and skin and into the abdomen. Joining the two catheters is a pressure regulatory valve. This serves to divert fluid into the abdomen where it can be absorbed. ...Read moreSee 1 more doctor answer
