Non-Aneurysmal Stenosis of the Popliteal Artery

Non-aneurysmal stenosis of the popliteal artery is a condition where the blood vessel in the back of the knee becomes narrowed, restricting blood flow. In simpler terms, it’s like a traffic jam in a crucial artery of the leg. This article will break down the key aspects of this condition in plain English to make it easy to understand.

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.
2. Inflammatory Stenosis:
   • Definition: Inflammation causing the artery to narrow.
   • Description: It’s like the road getting narrower due to swelling, making it harder for blood to pass.

Causes

1. Aging:
   • Description: As we age, the risk of plaque build-up in arteries increases.
2. Smoking:
   • Description: Smoking is like adding fuel to the fire, increasing the risk of inflammation and plaque.
