The most accurate method for checking brain pressure involves a procedure to directly measure the pressure inside the brain. This is often done in a hospital setting.
Intraventricular Catheter (IVC)
The intraventricular catheter is the most accurate monitoring method for checking brain pressure. Here's how it works:
- Drilling a Hole: A surgeon drills a small hole through the skull.
- Catheter Insertion: The catheter is inserted through the brain and guided into the lateral ventricle.
- Cerebrospinal Fluid (CSF): The lateral ventricle contains cerebrospinal fluid (CSF). The catheter measures the pressure of this fluid, which reflects the pressure inside the brain.
| Method | Accuracy | Procedure | Location | Fluid Measured |
|---|---|---|---|---|
| Intraventricular Catheter | Highest | Hole drilled in skull, catheter inserted | Lateral ventricle within the brain | Cerebrospinal Fluid (CSF) |
This procedure helps doctors accurately monitor and manage brain pressure, particularly in cases of head trauma, brain swelling, or other neurological conditions.
