Background: Oral anticoagulation therapy was the mainstay of deep vein thrombosis treatment but recently, catheter-directed thrombolysis has emerged as an alternative. Objective: To compare the efficacy and safety of the two strategies. Methods: Medline, Embase and Cochrane CENTRAL were reviewed. Outcomes of interest included post-thrombotic syndrome, thromboembolic events, mortality, bleeding risk and iliofemoral patency. A random effects model meta-analysis was performed. Heterogeneity was assessed with I square. Results: Four randomized controlled trials (RCTs) including 1005 patients met the inclusion criteria. Catheter-directed thrombolysis was more likely to prevent overall post-thrombotic syndrome compared to anticoagulation only (OR: 0.32; 95% CI: 0.12–0.85; I2=87.2%), and to lead to iliofemoral vein patency (OR: 2.7; 95% CI: 1.08–6.75; I2=55.3%) but no difference was noted in thromboembolic events (OR = 0.5; 95% CI: 0.08–3.02, I2=55.1%), bleeding and mortality rates. Conclusions: Catheter-directed thrombolysis can decrease post-thrombotic syndrome rates and improve iliofemoral vein patency compared to anticoagulation when used for the treatment of deep vein thrombosis.
