Of the total number of patients, 48.8% (n=139) had previous VBL: 20% (n=57) underwent primary prophylactic VBL and 34.7% (n=99) underwent secondary prophylaxis. Thus, 285 VBL procedures had been performed and the average number of VBL session was 2 (range 1-10)

Introduction. It is well known that portal vein thrombosis (PVT) can accelerate liver decompensation, reducing overall survival(1). In the literature, the topic whether PVT is a risk factor for variceal bleeding or it influences the effectiveness of variceal band ligation (VBL) remains of great interest
The aim of this study was to assess if VBL is a potential risk factor for PVT development. An observational and retrospective study was conducted in a single tertiary center from 2010 to 2021 and included data from 285 patients with liver cirrhosis.
Results. Of the 285 patients, gender distribution described 47.32% female (n =135) and 52.8% male (n =150) with a mean age of 55 years (range =23-79). The average MELD score was 12.5 (range 7-27).
Of the total number of patients, 48.8% (n=139) had previous VBL: 20% (n=57) underwent primary prophylactic VBL and 34.7% (n=99) underwent secondary prophylaxis. Thus, 285 VBL procedures had been performed and the average number of VBL session was 2 (range 1-10)
