Key result
Anticoagulation therapy using VKA for distal DVT showed a benefit with little or no difference in major bleeding, though clinically relevant non-major bleeding increased compared to placebo.
Why the study?
The optimal treatment for distal deep vein thrombosis is not clearly established, with debate over whether to use anticoagulation or close monitoring.
Does anticoagulation therapy using VKA reduce the recurrence of VTE and DVT in people with distal deep vein thrombosis?
Population
People with distal deep vein thrombosis
Comparison
Different treatment interventions including anticoagulation therapy vs no intervention or placebo

Supports VKA for distal DVT; reinforces RCT evidence with quantified recurrence benefit and bleeding trade-offs.
Meta-Analysis
Does anticoagulation therapy using VKA reduce the recurrence of VTE and DVT in people with distal deep vein thrombosis?
Anticoagulation with VKA for distal DVT appears beneficial for preventing recurrence without significantly increasing major bleeding, though it increases clinically relevant non-major bleeding.
Kirkilesis et al. (2020) conducted a meta-analysis in distal deep vein thrombosis (DVT). Anticoagulation therapy using VKA vs. no intervention or placebo was evaluated on recurrence of venous thromboembolism (VTE), DVT and major bleeding. Anticoagulation therapy using VKA for distal DVT showed a benefit with little or no difference in major bleeding, though clinically relevant non-major bleeding increased compared to placebo.
