Introduction
Occlusive portal venous system thrombosis (PVT) is significantly associated with poor outcomes in cirrhotic patients. Nonselective β-blockers (NSBBs) may be associated with the development of PVT. However, the role of NSBBs in progressing thrombosis remains unclear.
Methods
Forty-three patients on whom contrast-enhanced computed tomography or magnetic resonance imaging was performed twice, and for whom there was detailed information regarding NSBBs, were eligible in this study, including 16 in the NSBBs group and 27 in the no NSBBs group. A composite endpoint of progressing thrombosis included the development of PVT in patients without PVT and aggravation of PVT in patients with PVT. Logistic regression analysis was employed to identify the effect of NSBBs on the progression of PVT.
Results
At the last admission, 13 patients had progressing thrombosis. The incidence of progressing thrombosis was significantly higher in the NSBBs group than in the no NSBBs group [50.0% (8/16) vs. 18.5% (5/27), P = 0.030]. The use of NSBBs (odds ratio 4.400, 95% confidence interval 1.107–17.482, P = 0.035) was significantly associated with progressing thrombosis in univariate logistic regression analyses, but not significant (odds ratio 4.084, 95% confidence interval 0.488–34.158, P = 0.194) in multivariate logistic regression analyses.
Conclusions
NSBBs may play a role in the progression of PVT in liver cirrhosis. The benefits and risks of NSBBs in the management of liver cirrhosis should be fully weighed.
