BACKGROUND: Limited evidence is available on management of splanchnic vein thrombosis (SVT).
OBJECTIVES: This study aimed to evaluate safety and efficacy of direct oral anticoagulants (DOACs) for SVT treatment.
METHODS: Studies were systematically searched in the PubMed, Web of Science, and Scopus databases according to PRISMA guidelines. We assessed any recanalization, full recanalization, recurrence, mortality, and major bleeding as outcomes of interest. Results were reported as weighted mean prevalence (WMP) with 95% CI. Subgroup analyses and meta-regressions have been performed to address heterogeneity and adjust for potential confounders.
RESULTS: We included a total of 16 studies (17 datasets) on 648 patients with SVT treated with DOACs. We found any recanalization in 60.3% (95% CI: 41.8%-76.3%; I2 = 84.9%; P < .001) and full recanalization in 51.7% (95% CI: 36.0%-67.0%; I2 = 87.4%; P < .001). Recurrent venous thromboembolism occurred in 2.8% (95% CI: 1.4%-5.9%; I2 = 0%; P = .787) and death in 3.4% (95% CI: 1.6%-7.3%; I2 = 13.2%; P = .318) of patients. Major bleeding was reported by 5.8% (95% CI: 3.7%-8.9%; I2 = 29.2%; P = .125) of patients. Results were consistent when separately analyzing prospective studies, retrospective studies, studies on cirrhotic patients, and studies enrolling patients with portal vein thrombosis. Meta-regression analyses showed that an increasing age and cancer impacted the rate of recanalization. Cirrhosis was associated with a higher rate of major bleeding and mortality.
CONCLUSION: The results of the present study, mostly based on observational studies, suggest good safety and efficacy profiles of DOACs in patients with SVT. Randomized studies are needed to corroborate our findings.
