Analysis of related factors of portal vein thrombosis in liver cirrhosis

Background and aims To investigate the usefulness of interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-alpha), protein C (PC), and thromboelastography (TEG) to serve as a predictor of portal vein thrombosis (PVT) in patients with liver cirrhosis. Additionally, we examined the clinical significance of the above indicators in terms of disease progression. Methods A total of 123 patients with liver cirrhosis were recruited from May 2021 to December 2021, according to the imaging findings. They were divided into the PVT group (n = 52) and the non-PVT group (n = 71). Furthermore, patients with PVT were divided into plasma transfusion groups (n = 13) and non-plasma transfusion groups (n = 39). The basic general information, past medical history, laboratory, and imaging examination data were collected and analyzed. Results In univariate analysis, there was no significant difference between the two groups in IL-6, PC, reaction time (R), alpha angle (Angle), maximum amplitude, or coagulation index (CI) (P > 0.05). TNF-alpha in the PVT group was significantly lower than that in the non-PVT group (P = 0.001). K-time (K) in the PVT group was significantly higher than that in the non-PVT group (P = 0.031). There was no significant difference in IL-6, TNF-alpha, PC, or TEG between different Child-Pugh classification groups (P > 0.05). There were no significant differences in TEG between the plasma transfusion group and the non-plasma transfusion group. In Binary logistic regression analysis, TNF-alpha (OR = 0.9881, 95%CI = 0.971, 0.990, P < 0.001), K(OR = 1.28, 95% = 1.053, 1.569, P = 0.014), activate partial thromboplastin time (APTT) (OR = 0.753, 95%CI = 0.656, 0.865, P < 0.001), portal vein diameter (OR = 1.310, 95%CI = 1.108, 1.549, P = 0.002)and the history of splenectomy or embolism (OR = 7.565, 95%CI = 1.514, 37.799, P = 0.014)were related to the formation of PVT. Conclusions TNF-alpha, K, APTT, portal vein diameter, and splenectomy or embolism history were associated with PVT formation, but IL-6 was not.
