Exactly how common is vp shunt independence? Will young people eventually outgrow the need for one as they grow older?

Exactly how common is vp shunt independence? Will young people eventually outgrow the need for one as they grow older?

Shunt indepedence: A common asked question but a commonly unknown answer. Very few patients with shunts truly become independent, in my own experience it is probably only about 5%. There is a surgery, known as an iiird ventriculostomy where a hole can be made at the base of the brain to bypass the fluid obstruction — if successful the shunt can be removed but not all patients fulfill the criteria for this operation. ...Read more

How common is shunt independence (for vp shunts) how does it happen? Examples of such cases? What's the chance for hydro acquired after tumor removal?

How common is shunt independence (for vp shunts) how does it happen? Examples of such cases? What's the chance for hydro acquired after tumor removal?

Rarely useful: Theoretically, shunt independence can happen, and I have seen a few patients who may no longer need their shunt. Practically, it is rarely worth thinking about. There is no foolproof way to know if a shunt is still flowing or not. Even if the shunt is draining one drop per day, removing it would lead to return of hydrocephalus, so it's rarely worth trying, and usually best to leave it alone. ...Read more

Why does the reservoir of a vp shunt feel more flat at times? Does that mean there's not a lot to drain? Hydro resolved? Shunt independence?

Hydrocephalus shunts: The flatness comes from the reservoir being depress, it can take time to refill at which points it goes back to its normal contour. If it is refilling then you are likely still shunt dependent. ...Read more

How likely is shunt independence for acquired communicating hydrocephalus? Is it true that once you have a shunt, you're dependent on it forever?

How likely is shunt independence for acquired communicating hydrocephalus? Is it true that once you have a shunt, you're dependent on it forever?

Usually permanent: As a general rule, vp shunt should remain in place. For some the system develops a dependence on the shunt, for others, the shunt may not be necessary but the risk of injury during removal is too great. ...Read more

Is it common for CSF fluid to be drained in alternative passageways for acquired hydro after tumor removal? Chance of shunt independence in such case?

Yes: A shunt is necessary if there is too much cerebral fluid in the brain. The surgeon that put it in will check it periodically to see if it is functioning properly and if drainage needs to be increased or decreased. If there are no symptoms, the shunt is usually left alone. I know patients that have had them since childhood without any problems. Good luck. ...Read more

Why does right to left shunting happen?

A hole in the heart: It is literally a hole in the heart. Normally the right side of the heart pumps blood to the lungs to get the oxygen whereas the left side of the heart pumps blood to the body. A right to left shunt can cause some blood to bypass the lungs and not carry as much oxygen as it should. ...Read more

Which is worse left to right shunt or right to left? Can the shunting get better?

Not clear : The right to left shunt or left to right shunt is usually a congenital defect. The reasons for the defect can be varied but the left to right shunt is better to have but neither is good. The right to left shunt sends unoxygenated blood out to the body. Need to see a cardiologist with possibility of needing surgery. ...Read more

What is siphon/antisiphon? Do all vp shunts have these?

What is siphon/antisiphon? Do all vp shunts have these?

Siphon / Anti-siphon: No, all shunts do not have anti-siphon valves and there still remains some controversy whether they make a difference. In theory as you rise from recumbent or seated positions the shunt will "siphon" because of the sudden pressure change with elevation. These devices are supposed to prevent that and thus avoid over shunting, ie, draining too much fluid with resulting disturbances. ...Read more

Is hydrocephalus deadly if no. Shunt is implanted?

Is hydrocephalus deadly if no. Shunt is implanted?

Depends on cause: Hydrocephalus is just a word to describe too much fluid pressure in the brain. Some babies are born with the condition but become stable and never need a shunt. Some develop the condition due to brain tumor and the shunt just allows for less distress as the tumor is being treated. Some have the condition due to complex congenital abnormalities. In acute pressure, the shunt is life saving. ...Read more
