Percutaneous Endovenous Intervention Plus Anticoagulation versus Anticoagulation Alone for Treating Patients with Proximal Deep Vein Thrombosis: A Meta-analysis and Systematic Review.
Annals of Vascular Surgery 2018 May
BACKGROUND: Combination treatment with percutaneous endovenous intervention (PEVI) and anticoagulation has been proposed for treating lower-extremity proximal deep vein thrombosis (DVT). We performed a systematic review and meta-analysis of randomized controlled trials (RCTs) to assess the effect of PEVI plus anticoagulation versus anticoagulation alone in patients with lower-extremity proximal DVT.
METHODS: We systematically searched PubMed, Embase, and the Cochrane Library from inception to May 2016. All RCTs comparing clinical outcomes between additional PEVI and anticoagulation alone were included. The main end points were postthrombotic syndrome (PTS) and major bleeding complications. Secondary outcomes included the iliofemoral patency rate, venous obstruction, and recurrent DVT. We assessed pooled data using a random-effects model.
RESULTS: Four RCTs were included. PEVI plus standard anticoagulation compared with anticoagulation alone was associated with a lower rate of PTS (odds ratio [OR] 0.34, 95% confidence interval [CI] 0.18-0.63), significantly higher iliofemoral patency rate at 6 months and 12 months (OR 8.49, 95% CI 1.32-54.60), a lower rate of venous obstruction (OR 0.42, 95% CI 0.20-0.924), and a lower rate of recurrent DVT (OR 0.42, 95% CI 0.20-0.92). However, more major bleeding episodes occurred in the group with catheter-directed thrombolysis (Peto OR 5.86, 95% CI 1.76-19.48).
CONCLUSIONS: PEVI plus anticoagulation reduced the occurrence of PTS, recurrent DVT, and venous obstruction. Another advantage is an increased patency rate at 6 and 12 months. The disadvantage is an increased occurrence of major bleeding events.
