Duration of primary/secondary treatment to prevent recurrent venous thromboembolism: a systematic review and meta-analysis.

ABSTRACT:

Abstract

Antithrombotic therapy can prevent recurrent deep vein thrombosis (DVT) and pulmonary embolism (PE). It is, however, associated with an increased risk for major bleeding. This meta-analysis systematically reviewed the evidence regarding the duration of antithrombotic therapy to assess benefits and harms. We systematically searched for randomized controlled trials (RCTs) that compared shorter (3-6 months) with longer (>6 months) courses of anticoagulation for the primary treatment of venous thromboembolism (VTE) or that compared discontinued with indefinite antithrombotic therapy for the secondary prevention of VTE. Pairs of reviewers screened the eligible trials and collected data. This study included 22 RCTs (11 617 participants). Pooled estimates showed that, for the pri
