Anticoagulation may be an effective option for patients with superficial venous thrombosis and are at high risk of venous thromboembolism (VTE), according to an evidence-based review by Dr. Joseph Raffetto and Dr. Robert Eberhardt.
In particular, they reviewed the results of three clinical trials with a total of nearly 1400 patients: STENOX, STEFLUX, and CALISTO.
Based on their assessment, Dr. Raffetto and Dr. Eberhardt, summarized that surgery and anticoagulants were both acceptable treatments for SVT patients at high risk of VTE, who had severe symptoms, who presented with close proximity to the saphenofemoral junction, or who had recurrence. Anticoagulants seemed to have fewer complications and a lower VTE rate than did surgery. However, treating all SVT patients with anticoagulants is not recommended because of cost concerns.
While anticoagulants do appear to be an effective treatment for SVT, “it is not known if SVT is causative of or an epiphenomenon for VTE. The optimal treatment of SVT is unknown with respect to selection of patient and vein, preferred therapy, and timing and duration of therapy,” the authors cautioned.
