Fibromuscular Dysplasia of the Posterior Tibial Artery

Fibromuscular Dysplasia (FMD) is a rare but important condition that affects blood vessels, particularly the posterior tibial artery. In this article, we’ll break down the complexities of FMD in simple terms, covering types, causes, symptoms, diagnostic tests, treatments, drugs, and surgical options.

Types of Fibromuscular Dysplasia:

FMD can manifest in different ways, with the following common types:

1. Medial FMD: Affects the middle layer of the arterial wall.
2. Intimal FMD: Involves the inner layer of the artery.
3. Adventitial FMD: Affects the outer layer of the artery.

Understanding the Causes
