Vascular Liver Disease: Emerging Concepts in the Sinusoidal Space

Area of Science:

• Hepatology
• Vascular Biology
• Pathology

Background:

• Liver vascular pathology encompasses diseases affecting the liver's dual blood supply.
• Portal vein diseases are linked to thrombosis, while central vein diseases associate with heart failure and Budd-Chiari syndrome.
• Sinusoidal vascular disease is less characterized, with emerging concepts requiring further exploration.

Purpose of the Study:

• To review and synthesize current knowledge on vascular liver pathology.
• To highlight emerging concepts in sinusoidal-based vascular liver disease.
• To provide a comprehensive overview of liver vascular conditions impacting different microanatomic sites.

Main Methods:

• Literature review of vascular liver pathology.
• Synthesis of information on portal, central, and sinusoidal vein diseases.
• Discussion of emerging concepts in sinusoidal vascular pathology.

Main Results:

• Vascular liver diseases are heterogeneous, influenced by liver microanatomy.
• Portal and central vein diseases are relatively well-described.
• Sinusoidal vascular disease represents an area with limited characterization and active research.

Conclusions:

• Understanding liver vascular pathology requires considering distinct microanatomic sites.
• Further research into sinusoidal vascular disease is crucial for comprehensive liver disease management.
• This review consolidates current understanding and points to future research directions in liver vascular pathology.
