A comparison of low-molecular-weight heparin and combined therapy of low-molecular-weight heparin with an anti-inflammatory agent in the treatment of superficial vein thrombosis

摘要

Objectives: The optimal treatment of superficial vein thrombosis (SVT) of the leg has not been determined yet. The aim of this study is to evaluate the efficacy of low-molecular-weight heparin (LMWH) as compared with combined therapy of LMWH with an anti-inflammatory agent in treatment of SVT. nnMethods: Fifty patients with SVT of the greater saphenous vein were randomly assigned to be treated with Ca-nadroparin 190 IUAxa/kg in a single dose or with same dose of Ca-nadroparin and 60 mg oral acemetacine twice daily for 10 days. The efficacy of the two treatments to relieve symptoms and signs was evaluated by using visual analogue scale. nnResults: Significant improvements were achieved for both groups after the treatment in terms of all four symptoms (P < 0.001). Treatment scores were in favour of LMWH with anti-inflammatory agent treatment group to relieve all four symptoms. The most significant and remarkable results obtained were for the reduction of pain and local tenderness (P < 0.05). No patient experienced major complications or mortality in either group. nnConclusion: The results of this study suggest that the combined therapy of LMWH with an anti-inflammatory agent is more effective than LMWH. It may be an important option in the standard treatment of SVT.
