Arteriosclerotic stenosis of the posterior tibial artery refers to the narrowing of this important blood vessel in the lower leg due to the buildup of fatty deposits (plaques). This condition can impede blood flow, leading to various complications. In this article, we’ll break down the types, causes, symptoms, diagnostic tests, treatments, drugs, and surgery options associated with this arterial issue.
Types:
Arteriosclerotic stenosis can manifest in different forms:
- Localized Stenosis: Narrowing occurring in a specific part of the posterior tibial artery.
