Sinusoidal and postsinusoidal vascular systems in liver cirrhosis
Hepato-Gastroenterology
|October 1, 1981
Summary
Liver cirrhosis disrupts the normal hepatic vein system, causing stenosis and displacement. This altered angioarchitecture impacts liver hemodynamics and pressure measurements.
Area of Science:
- Hepatology
- Vascular Anatomy
- Pathology
Background:
- Liver cirrhosis significantly alters liver structure.
- The hepatic vein system's morphology in cirrhosis is not fully understood.
Purpose of the Study:
- To investigate the morphological changes in the sinusoidal and hepatic vein system in liver cirrhosis.
- To correlate these changes with clinical implications.
Main Methods:
- Postmortem venography
- Microangiography
- Micropreparation
Main Results:
- Cirrhosis leads to loss of normal angioarchitecture in the hepatic vein system.
- Hepatic veins exhibit stenosis and displacement.
- Regenerative nodules, pseudolobules, and vascularized septa characterize the cirrhotic liver's venous system.
Conclusions:
- The disordered intrahepatic angioarchitecture in cirrhosis is a key finding.
- These morphological alterations have significant clinical relevance for liver hemodynamics and hepatic venous pressure measurements.
