Degenerative Stenosis of Ulnar Artery

Degenerative stenosis of the ulnar artery is a condition where the ulnar artery, a blood vessel in the forearm, narrows and restricts blood flow over time. This can lead to various symptoms and complications. In this article, we will delve into the types, causes, symptoms, diagnostic tests, and treatments for this condition in simple, easy-to-understand language.

Types:

Degenerative stenosis of the ulnar artery primarily presents as two types:

1. Atherosclerosis-Related Stenosis:
   • Definition: Atherosclerosis occurs when fatty deposits build up on the artery walls, leading to the narrowing of the ulnar artery.
   • Description: Over time, these deposits can harden and reduce blood flow, affecting the surrounding tissues and causing symptoms.
2. Thrombotic Stenosis:
   • Definition: Thrombosis refers to the formation of blood clots within the ulnar artery, leading to blockages and restricted blood flow.
   • Description: Clots can form due to various factors, hindering normal blood circulation and causing symptoms associated with diminished blood supply.

Causes
