Abstract
AbstractBackground & AimsPatients with cirrhosis are considered in a haemostatic balance, though weaker than in normal subjects. In these patients, however, the use of pharmacological prophylaxis for venous thromboembolism (VTE) remains controversial. Therefore, in this study, we aimed to assess the safety and efficacy of VTE prophylaxis in patients with cirrhosis.MethodsWe conducted a systematic review of studies reporting the occurrence of bleeding and VTE events in patients with cirrhosis, and controls, undergoing VTE prophylaxis. Meta‐regression analysis was conducted to further explore the determinants of heterogeneity in the study of the occurrence of either bleeding or VTE events.ResultsIn a total of 10 studies, including 5712 patients, of which 2330 undergoing VTE prophylaxis, bleeding (n = 5513) and VTE events occurred in 8.2% and 2.8% patients respectively. A total of 2963 and 3162 patients were included from low‐risk of bias studies in bleeding and VTE analysis respectively: while administration of VTE prophylaxis did not seem to reduce VTE (OR = 1.07, CI 0.39–2.96, p = .89), importantly prophylaxis was not associated with increased bleeding risk (OR = 0.56, CI 0.20–1.59, p = .27). Meta‐regression analysis showed that no parameter significantly influenced the heterogeneity of data regarding bleeding or VTE events.ConclusionsIn patients with cirrhosis, current evidence is insufficient to advise for or against the use of VTE prophylaxis, mainly due to lack of quality and homogeneity of available data. However, its use does not appear to be associated with a significant bleeding risk. Adequately designed studies are required to provide a measure of its overall utility.
