What's the chance (percentage) that an MRI will change the settings on a codman hakim programmable vp shunt? Can anything else change it?

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 more

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?

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 more

If codman hakim programmable vp shunt is set at 140, how much fluid is being drained?

Dr. Richard Kim

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 more

What's are the difference between the three available programmable shunts commonly used to treat hydrocephalus?

Several Differences: 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. Disclosure: i work for one of the companies that make these devices. ...Read more

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

What is a shunt?

Shunt: A shunt is a structure or device that transfers body fluid or blood from one area of the body to another area. For example shunts are fashioned to relieve high pressure areas of cerebro spinal fluid by shunting the fluid away to low pressure areas. ...Read more
