Abstract

Objective: Describe the characteristics of the termninal thoracic duct (TTD) in patients with cirrhosis - portal hypertension by ultrasound and evaluate the correlation between the degree of dilatation of the TTD with some manifestations of cirrhosis. Materials and Methods: Cross-sectional descriptive study, 30 patients were diagnosed and treated for cirrhosis at Hanoi Medical University Hospital from December 2023 to July 2024. Results: 30 cirrhosis patients (27 men: 3 women; mean age 60,3 ± 9,7 years); 08 Child Pugh A patients (26,7%), 16 Child Pugh B patients (53,3%), and 06 Child Pugh C patients (20%) with mean diameter TTD is 3,89 ± 0,94mm. The average level of esophageal varices is grade II. The dilation of portal veins occurs in 16 patients (53,3%) with the average diameter of the portal vein is 12,7±3mm by sonography. Ascites occurs in 21 patients (70%) and mainly in group 2 (66,67%). TTD  is dilated in the range of 3 to <5mm (group 2) accounts for a higher rate (77,4%) than group 3 (16,1%) and group 1 (6,4%). The degree of dilatation of TTD is closely correlated with the degree of cirrhosis (r = 0,54; p = 0,02 < 0,05) and the degree of portal hypertension - assessed indirectly by ascites (r =0,39; p=0,03), portal varix (r=0,37; p=0,04) and esophageal varices with (r=0,39; p=0,03). Conclusions: Diameter of TTD increases in patients with cirrhosis and correlates with the severity of cirrhosis and portal hypertension
