All right, so welcome back to the Internet Book of Critical Care podcast.

I'm here with Adam Thomas, and we're going to talk about cerebral venous sinus thrombosis.

And then we'll rebrand it so we get more likes and downloads, Josh, DVT of the brain.

It's DVT PE of the brain.

Hashtag DVD of the brain.

So all things today, anatomy, anatomy, anatomy, important for you to remember where these big veins are.

Josh will cover pathophysiology.

Who gets this?

Signs and symptoms to work up.

And more importantly, how do we treat this?

So Josh, let's get straight into it, pathophysiology.

What is going on with these veins?

Because they don't make sense from the arterial side that I remember from strokes.

There's some pictures in the chapter that kind of map out the venous system of the brain,

but it's a little complicated.

And the interesting thing about it is that there aren't valves in the brain.

So blood can go from different areas and can be rerouted to a certain extent, kind of like other venous networks. I mean, this can cause a certain amounts of confusion because

there's some redundancy, but not a ton of redundancy. So at a certain point, if enough obstruction

occurs, then tissue can start getting infarcted because there's simply no outflow.

Compartment syndrome of the brain, right? Critical care? All about DO2, V-O-2 and compartment syndromes. So, Josh, the

valves we discussed, there's an attraumatic and a traumatic population, but more importantly,

let's talk about some sequelae of this. So I block up the venous drainage that can get
