A Study of the Correlation Between Portal Vein Thrombosis and Prognosis of Liver Transplantation

What this Trial Is About

Researchers are studying the connection between portal vein thrombosis PVT and outcomes after liver transplantation. The study aims to find out how common PVT is, what risk factors contribute to it, and how having PVT before surgery affects the prognosis of liver transplant patients. The goal also includes developing a new grading or rating system for PVT to improve clinical care. Participants are grouped into those with PVT and those without PVT before their liver transplant. The study does not involve any treatment or intervention but observes and compares data from both groups. Medical imaging, surgical details, pathology reports, treatments after surgery, and follow-up information will be collected and analyzed to understand PVTs impact. During the study, researchers will gather demographic and laboratory data, imaging results, and clinical outcomes over time. The main outcomes measured include death, postoperative PVT, and portal vein narrowing over a 10-year period, along with complications within 1 year after surgery. The study monitors participants through their clinical records to build predictive models and clarify how PVT influences transplant prognosis.
