BackgroundTransjugular intrahepatic portosystemic shunt (TIPS) is widely applied to decrease portal hypertension. Because of the lack of strong evidence, it is controversial whether anticoagulation should be performed after TIPS. This meta-analysis aimed to assess the safety and efficacy of anticoagulation for patients with portal hypertension following TIPS.MethodsStudies making comparisons between combination treatment and TIPS alone were searched in China National Knowledge Infrastructure, Cochrane Library, PubMed, the Wan Fang electronic databases, and EMBASE, delivered between the earliest accessible date and September 4, 2021. The RevMan version 5.3 was applied to conduct all statistical analyses. I2 index statistic was used to assess heterogeneity.ResultsFive eligible studies were selected, and total 707 patients were enrolled. According to the meta-analysis, compared to TIPS alone, TIPS + anticoagulation led to much lower incidence of portal vein thrombosis (PVT; odds ratio [OR] = 0.39, 95% confidence interval [CI] 0.18-0.84, P = .02) as well as low heterogeneity (P = 0.36, I2 = 3%). Other index like the stent dysfunction rate (OR = 1.27, 95% CI 0.71-2.77, P = .42), bleeding rate (OR = 1.27, 95% CI 0.71-2.77, P = .42), and incidence of hepatic encephalopathy (OR = 0.87, 95% CI 0.56-1.36, P = .55) showed no statistical significance.ConclusionsIn certain patients with portal hypertension, anticoagulation following TIPS may not be required. However, for patients who do not have a PVT before TIPS, post-TIPS anticoagulation can decrease the incidence of PVT. Nonetheless, further research is still required.Copyright © 2022 the Author(s).
