Behind the knife, the Surgery Podcast, where we take a behind the scenes intimate look at surgery

from leaders in the field. Welcome to Behind the Knife Medical Student and Intern Survival Guide.

In this podcast series, we focus on high yield topics relevant to medical students and surgical interns. My name is Patrick Georgeoff and

I'm Vahad Nicolian and we are your hosts. We've got a great super high-yield

vascular surgery episode for you today. That's right. We've got some great cases that will

really help you lock down on the key concepts required for managing

patients with carotid stenosis, abdominal aortic aneurysms, and limb

eschemia.

We want to give a big thank you to Drs Peter Henke and Nick Osborne for reviewing the content

as well.

So let's go ahead and get started.

Patrick, why don't we start with Corrodit stenosis? What is it and why do we care?

Yeah, so Corrada stenosis is narrowing of the carotid artery by atheroschrotic plaque and the location most frequently affected by

atherosclerosis is a carotid bifurcation often with extension into the proximal

internal carotid artery. So this is thought to occur because the unique flow dynamics at the

bifurcation. Progression of atheroskrotic plaque at the crowded

bifurcation results in luminal narrowing and this can often be accompanied

by ulceration of the plaque itself and this process can lead to

ischemic stroke or transient ischemic attack from embolization, thrombosis, or human dynamic

compromise.

All right that sounds like some bad complications associated with Corodid stenosis.

So do we screen for it?
