Porto-sinusoidal vascular disease (PSVD) is a group of liver conditions causing portal hypertension without cirrhosis. This review explores PSVD assessment, treatments, and remaining questions for this increasingly recognized disorder.
Area of Science:
- Hepatology
- Vascular Biology
- Gastroenterology
Background:
- Porto-sinusoidal vascular disease (PSVD) is a recently defined group of liver conditions.
- PSVD leads to portal hypertension (PH) without cirrhosis or portal vein thrombosis (PVT).
- Recognition and understanding of PSVD are growing, consolidating knowledge from previous terms.
Purpose of the Study:
- To review current methods for assessing PSVD.
- To discuss available treatments for PSVD and its complications.
- To highlight challenges and unanswered questions regarding PSVD nomenclature and management.
Main Methods:
- Review of clinical features, histological findings, and imaging techniques for PSVD diagnosis.
- Analysis of current treatment strategies for PSVD and associated portal hypertension.
- Discussion of diagnostic challenges and future research directions.
Main Results:
- PSVD encompasses conditions previously known by various names, excluding specific etiologies.
- Patients with PSVD can develop complications of PH, similar to cirrhosis.
- Advances in diagnostics and treatments are improving outcomes for patients with associated conditions.
Conclusions:
- PSVD is an increasingly recognized cause of portal hypertension.
- Further research is needed on PSVD's natural history, screening, prognosis, and optimal treatment.
- Standardized assessment and management strategies are crucial for this evolving liver disease.
