Portal Vein Thrombosis in Liver Cirrhosis: Clinical Characteristics, Radiological Patterns, and Predictors (Thrombosis)
Portal vein thrombosis (PVT) is a common complication in patients with liver cirrhosis and is associated with increased morbidity due to worsening portal hypertension and hepatic decompensation. The clinical presentation and radiological patterns of PVT vary widely, and the factors predicting its development remain incompletely understood.
This observational study will include adult patients (≥18 years) with established liver cirrhosis who are admitted to the Department of Gastroenterology and Tropical Medicine, Al-Rajhi Liver Hospital, Assiut University. Eligible participants will undergo routine screening for PVT using Doppler ultrasonography, with confirmation by contrast-enhanced computed tomography when indicated.
The study aims to evaluate the clinical characteristics, laboratory parameters, and radiological features of PVT. Cases of PVT will be classified according to extent (partial or complete) and anatomical location (main portal vein, right branch, left branch, or combined involvement). Clinical and laboratory data will be analyzed to identify potential predictors associated with the development and severity of PVT.
The findings of this study are expected to improve understanding of the risk factors and radiological patterns of PVT in cirrhotic patients, contributing to better risk stratification and clinical management.
