Vascular liver diseases on the clinical side: definitions and diagnosis, new concepts

Area of Science:

• Hepatology
• Vascular Biology
• Internal Medicine

Background:

• Hepatic vascular system components (veins, sinusoids, lymphatics) are susceptible to injury.
• Rare vascular liver conditions historically lacked sufficient research and awareness.
• Recent international collaborations have significantly advanced understanding and management.

Purpose of the Study:

• To review definitions, nomenclature, and diagnostic approaches for liver vascular disorders.
• To provide an overview of evolving pathogenic and pathophysiologic insights.
• To focus on conditions excluding those affecting hepatic arteries.

Main Methods:

• Literature review and synthesis of current knowledge.
• Analysis of data from international collaborative efforts.
• Discussion of diagnostic criteria and clinical perspectives.

Main Results:

• Established updated definitions and diagnostic criteria for rare hepatic vascular disorders.
• Highlighted advancements in understanding pathophysiology driven by collaborative research.
• Provided a comprehensive overview excluding hepatic artery conditions.

Conclusions:

• Improved understanding and management of rare liver vascular diseases are evident.
• International collaboration is key to advancing knowledge in rare conditions.
• Accurate diagnosis and understanding pathophysiology are crucial for clinical practice.
