Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Study population: This study includes adult patients aged 18 years and older with histopathologically confirmed porto-sinusoidal vascular disease (PSVD) via liver biopsy and no histological evidence of cirrhosis. All subjects are inpatients and outpatients from Beijing Ditan Hospital, covering subgroups with or without portal vein thrombosis, portal hypertension, known etiologies or concurrent chronic liver diseases. Patients with Budd-Chiari syndrome, hepatic venous outflow obstruction, congenital hepatic fibrosis, sinusoidal obstruction syndrome, hepatic malignancies or severely incomplete clinical data are excluded.

Who may be able to join

  • Patients histopathologically diagnosed with porto-sinusoidal vascular disorder (PSVD) via liver needle biopsy;
  • Liver biopsy specimen length ≥ 10 mm (or assessed as diagnostically adequate by a pathologist), with no histological evidence of cirrhosis;
  • Meeting the established diagnostic criteria for PSVD.

Who cannot join

  • Concomitant Budd-Chiari syndrome or other hepatic venous outflow obstruction diseases;
  • Concomitant congenital hepatic fibrosis, hepatic sarcoidosis, or sinusoidal obstruction syndrome;
  • Concomitant hepatocellular carcinoma or other hepatic malignancies;
  • Age < 18 years;
  • Severe deficiency of clinical data that precludes valid analysis.

About this study

Official title: Study on Clinicopathological Features, Influencing Factors and Clinical Outcomes in Patients With Porto-sinusoidal Vascular Disease (PSVD)

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.

Read the detailed description

The study aims to include approximately 100-150 patients with histopathologically confirmed PSVD by liver biopsy, covering subgroups with/without definite etiology, with/without PVT, with/without portal hypertension, etc. Collect demographic, clinical, laboratory, imaging and pathological data of enrolled patients. Follow up endpoints including transplant-free survival, liver-related events and dynamic changes of PVT. Apply Cox regression, Kaplan-Meier method and Fine-Gray model to identify independent prognostic factors and compare prognosis differences among subgroups, so as to provide reference for clinical diagnosis and treatment of PSVD.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Transplant-free survival

    Time from study enrollment to all-cause death or liver transplantation, whichever occurs first.

    Measured: From baseline through Month 36, with outcome status assessed at Months 6, 12, 18, 24, 30, and 36, or until all-cause death or liver transplantation, whichever occurs first.

Secondary outcomes (1)
  1. Liver-related composite events

    Occurrence of variceal bleeding, refractory ascites, hepatic encephalopathy, PVT progression or hepatic decompensation.

    Measured: From baseline through Month 36, with outcome status assessed at Months 6, 12, 18, 24, 30, and 36, or until all-cause death or liver transplantation, whichever occurs first.

Questions about this trial

What is this clinical trial studying?

An observational study of Porto-Sinusoidal Vascular Diseases, run by Beijing Municipal Administration of Hospitals at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: opening soon, as of the sponsor's last update on 4 Aug 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Minghui Li, Dr (+8613693259096, wuhm2000@sina.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Transplant-free survival (time frame: From baseline through Month 36, with outcome status assessed at Months 6, 12, 18, 24, 30, and 36, or until all-cause death or liver transplantation, whichever occurs first.). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 4 Aug 2026.
