Ulnar Artery Cholesterol Embolism (UACE) is a medical condition characterized by the release of cholesterol crystals into the bloodstream, which can lead to blockages in the ulnar artery. This condition may cause various symptoms and complications, necessitating prompt diagnosis and appropriate management. In this article, we will explore the types, causes, symptoms, diagnostic tests, treatments, drugs, and surgical options related to UACE, presented in simple and accessible language.
