Official title
Randomized Trial of Rivaroxaban (Xarelto) and Apixaban (Eliquis) for the Prevention of Endothermal Heat-Induced Thrombosis (EHIT) and Deep Vein Thrombosis After Great Saphenous Vein Endovenous Laser Ablation
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Endothermal heat-induced thrombosis (EHIT) is a thrombotic complication specific to endovenous thermal ablation of the great saphenous vein (GSV), for which no prophylactic regimen is standardized. This single-centre, single-operator randomized trial compared a brief 5-day post-procedural course of the direct oral anticoagulants apixaban and rivaroxaban against no anticoagulation for the prevention of EHIT after GSV endovenous laser ablation performed with concurrent below-knee foam sclerotherapy. Treated limbs were randomly allocated 2:1:1 (no anticoagulant : rivaroxaban : apixaban), and EHIT was graded on post-ablation duplex by the American Venous Forum (AVF) classification.
