Degenerative stenosis of the popliteal artery is a condition where the blood vessels in the knee area narrow over time, restricting blood flow. In simpler terms, it’s a problem with the arteries in your legs. Let’s break down the key aspects of this condition to make it easy to understand.
Types:
There are two main types of degenerative stenosis:
- Atherosclerotic Stenosis:
- Definition: Narrowing of the popliteal artery due to the buildup of fatty deposits.
- Explanation: Think of it like clogged pipes, where cholesterol and other substances accumulate, reducing the space for blood flow.
- Fibromuscular Dysplasia (FMD):
- Definition: Abnormal growth in the artery walls leading to stenosis.
- Explanation: Picture the artery walls becoming thicker in an irregular way, causing narrowing and hindering proper blood circulation.
