Study on Clinicopathological Features, Influencing Factors and Clinical Outcomes in Patients With PSVD

Sponsor: Beijing Municipal Administration of Hospitals

Summary

This retrospective-prospective cohort study investigates portal sinusoidal vascular disorder (PSVD), a liver vascular disease definitively diagnosed via liver biopsy. Addressing PSVD's poorly defined natural history, unclear prognostic determinants and the scarcity of large-scale systematic research in China, the study enrolls histopathologically confirmed patients, collects baseline clinicopathological, laboratory and imaging data, tracks endpoints including transplant-free survival, liver-related events and portal vein thrombosis changes, and conducts prognostic analyses using Cox regression, Kaplan-Meier method and Fine-Gray model, aiming to characterize disease features, identify key prognostic factors, verify high-risk subgroups with inferior outcomes, and support precise clinical management while filling relevant domestic research gaps.
