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

Shunt (Definition)

Device that allows the flow of usually a fluid between two places. Sometimes a shunt may be used during carotid endarterectomy surgery to maintain the blood flow to the brain while the carotid artery ...Read more

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

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

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 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

Can a ventriculoperitoneal shunt be used to drain a baby hydrocephalus?

Can a ventriculoperitoneal shunt be used to drain a baby hydrocephalus?

That's one way: The current approach to hydrocephalus is dependent on the kid and the training of the neurosurgeon involved in their care. There are several ways to shunt the excess with VP shunting to be a traditional one. ...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

I have hydrocephalus since birth. I have a programmable shunt. Over a couple of days I am now getting neck pain. Is this normal?

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

How does a shunt work to treat hydrocephalus?

How does a shunt work to treat hydrocephalus?

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 more

Can a child stop needing a shunt for hydrocephalus?

Can a child stop needing a shunt for hydrocephalus?

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 more

What kinda shunt would be for spinal flow blockege?

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

How can a neurosurgeon tell if a shunt is overdraining?

How can a neurosurgeon tell if a shunt is overdraining?

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

How dangerous is having a shunt put in for hydrocephalus?

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 more

My child does not have a shunt, does he/she still have hydrocephaly?

Possibly: I imaging you are asking that if your child has increased fluid in the brain, but not a shunt does that mean there is hydrocephaly. Yes, any increase in fluid is hydrocephaly. Sometimes a shunt is not needed because the brain tissue is not impacted and sometimes, if the hydrocephaly is not under pressure, a shunt will not help. ...Read more

Are there any options other than a shunt to help with hydrocephalus?

Possibly.: Hydrocephalus is caused by a blockage in cerebrospinal fluid flow. Depending on exactly where the blockage is, it might be amenable to an endoscopic 3rd ventriculostomy, where a small hole is punctured in the floor of the third ventricle to relieve the blockage. No external shunt is needed in these cases. If the blockage is in the wrong area however, this will not work. ...Read more

Are there tests to see if I still have hydrocephalus? I have a shunt.

CT & Neuro tests: Generally, hydrocephalus poses specific neurologic signs & symptoms (Sx), which lead 2 testing. Dilated ventricles (fluid sacs in brain) can b seen on CT scan. U may have "frozen ventricle" meaning an abnormal CT scan w/o Sx; or shunt malfunction w/ Sx. If u r having symptoms like when u were 1st diagnosed, TTY neurologist, who can perform specific neurologic tests (tandem walk, etc.) 4 diagnosis. ...Read more

What are things that are bad for vp shunts bc I wanna extend the life of it as much as possible?

Hydrocephalus: Ventriculoperitoneal (VP) shunts are remarkably durable six weeks after implantation. Thereafter, the risk of malfunction is 1%/year and the silicone tubing and valve can last 25 years. The VP shunts are self-sufficient and no maintenance is required. Valve adjustments may be necessary from time to time but this is infrequent too. ...Read more
