Non-Aneurysmal Stenosis of the Popliteal Artery

Types:

Non-aneurysmal stenosis can be classified into two main types:

1. Atherosclerotic Stenosis:
   • Definition: Build-up of fatty deposits (plaque) in the artery, leading to narrowing.
   • Description: Imagine a pipe clogged with cholesterol, restricting the flow of water.
