Welcome. My name is Devine. This is episode 468 of the Devine Intervention Podcast. In today's

podcast, I'm going to be going to be continuing the rapid review series for the US

at least two seeking and Step 3 exams.

This is going to be Series 98.

So let's go ahead and jump right into it.

So what if they give you a question about a patient?

They tell you that for the last two hours he has been

having a very severe headache and they tell you that he has vision loss in both eyes. In fact it is mentioned that he has lost vision in

the outer half of both eyes. If you see something like that, what should he be thinking about?

Well, I would hope that you'd be thinking about some kind of stroke. In fact, if you wanted to maybe be smarter about

about localizing it, I would think about an anterior communicating artery

stroke. The person basically has bi-temporal hemianopsia. So what's the deal there? Well, the deal here is that this person

probably had some kind of aneurysm in the Circle of Willis and then that aneurysm ruptured and then as a result of

that you had like bleeding in the anterior part of the brain. You have like a bi-temporal

hemianopsia. In fact, if you won't have just an aneur

the anterior communicating artery, that can certainly compress the optic chisimidin,

and you can get a biteminalopsia.

Remember when I'm pressing as a biteminalopsia, the high old thing to know is that

you're going to lose your outer visual field in both eyes, your outer visual field in both eyes.

So like the outer half in both eyes, that's going to be bi temporal hemianopsia.

So now the big question then begs, who are the people that typically get

an erosions in the circle of Willis? Well, I mean, normal people can get an erosimps in the Circle of Willis, but our friends at the USMLEs, they also love if you know certain diseases that have these associations.
