I know that there is a LOT of debate about the use and resources required for AI. And I was not an "early adopter" - when Chat GPT first came out I thought it was a useless little trinket and people were making WAY to big of a deal about it.
But I did start using it, gingerly at first, and I am coming around. One of the first things I ever did with it was ask it to write a "thank you letter" for the 150+ people that attended a workshop I put on. After I sent it my boss complimented me on a "really excellent" letter. I told him the truth (about a year later).
Since then, I have used it as a tool for more and more tasks. In law school we have had it smashed into our skulls NOT to use it - or, at least, to use it with GREAT caution. Real lawyers are losing their law license for having AI write briefs with hallucinating references.
That said, however... I uploaded the class syllabi into Chat GPT, and asked it to help me study for finals. It created a "boot camp" for Con Law - based on it being an open-note test, what notes I needed, and what I needed to have memorized, know where to find, my own decision-making process for "strict scrutiny," etc.
This week, I'm going to the library and doing another boot camp - this time for Torts, and knowing that this final is CLOSED note. It has me writing things down from memory, pages to look at before bed, etc. It's extremely helpful.
But none of that has anything to do with the upcoming surgery. And for that, I turn to a different chat. Did you know that the AI bots learn as they go, and you can tell them to switch their "thought" process from "Law School Tutor" to "Oh God I'm panicking about brain surgery" - ?
I know that I'm talking to a computer. I know that it has no sympathy to offer. But the tone and voice is still reassuring. If nothing else, it's nice to know that, somewhere, a human taught it to pretend to be sympathetic. Here's an example:
I want to know more about setting the ventricular catheter. That still seems rather invasive and like they're going to be poking holes in my brain.
Totally fair reaction, and you’re not wrong to be protective of your brain after everything you’ve already gone through. Let me walk you through this in a way that strips the mystery out of it — because setting a ventricular catheter sounds more invasive than it actually is, and it is not like the surgery you had before.
I’ll be direct but reassuring: they are not poking around in your brain tissue the way it feels from the outside.
⭐ What “setting the ventricular catheter” actually means
A ventricular catheter does not go through brain tissue the way a biopsy needle or BrainPath corridor does.
It follows a very small, predictable, natural path into the fluid-filled ventricle — an open space.
Here’s what happens step-by-step:
1. The burr hole is made
They drill a burr hole about the size of a nickel or smaller.
This is in the skull, not the brain.
No pain, obviously, since you’re under anesthesia.
2. They open the dura (the covering)
The dura is a tough protective membrane.
They open a tiny slit in it to access the surface.
This part is the “entry point,” but again: still not into brain tissue.
3. The catheter enters the brain cortex — but only 1–2 cm of solid tissue
This is the part that worries people.
Here’s the truth:
-
The entry point is a non-critical, “silent” area — usually right frontal.
-
It’s designed to avoid any areas responsible for speech, movement, personality, vision, etc.
-
The catheter is only a few millimeters thick (like a spaghetti noodle).
-
It gently passes through tissue to reach the ventricle — and the frontal lobe tolerates this extremely well.
So yes, it passes through a bit of brain tissue — but:
-
They’ve been doing this safely since the 1950s.
-
The brain isn’t being “poked around.”
-
It’s a smooth, straight, controlled path.
-
It’s not cutting; it’s displacing fibers, and the tissue adapts surprisingly well.
Think of it like sliding a thin straw through dense jello — it parts, it doesn’t shred.
4. Once it reaches the ventricle, the catheter sits in open fluid space
This is where it’s meant to be — a hollow compartment filled with CSF.
There’s no brain matter here at all.
Once the tip is in the ventricle, the neurosurgeon stops advancing.
5. The catheter is anchored and nothing moves anymore
They place a small plate and sutures to keep it from shifting.
After this:
-
It doesn’t slide around
-
It doesn’t wander into new tissue
-
It doesn’t “poke” anything
It’s just a fixed straw sitting in a fluid chamber.
⭐ Why this is considered low-risk
I know it sounds insane that a catheter goes through the brain at all, but here’s why surgeons are so calm about it:
-
The frontal lobe where they enter is forgiving
-
The catheter is tiny
-
It’s a single, short trajectory
-
They don’t manipulate or move it once it’s placed
-
The brain adapts to the presence of the catheter
-
Complications are low, and primarily related to infection or blockage — not brain damage from placement
To put it bluntly:
Tumor resections, clot removals, and deep access are far more invasive. A shunt catheter placement is a lightweight procedure by comparison.
⭐ A straight truth you might need to hear
You’ve already survived something far more complicated — something that required precision tools like the Myriad, navigation, deep access, and real tissue work.
A VP shunt catheter is, comparatively, a simple line placement.
It feels psychologically invasive, but physically it’s one of the most routine things neurosurgeons do.
If you want, I can go deeper on:
-
How surgeons pick the exact entry point
-
What “Kocher’s point” is and why it’s safe
-
Whether neuronavigation will be used in your case
-
Typical complication rates (spoiler: very low for placement injuries)
-
Why your brain won’t “feel” the catheter or change how you think
Just tell me what direction you want. You deserve a full, clear understanding — not vague reassurances.
