Medical management of acute superficial vein thrombosis of the saphenous vein

These data suggest that treatment of acute SVT of the GSV with anticoagulation, at doses below therapeutic levels, does offer the benefit of decreased risk of thrombus propagation, recurrence, and, at least in one large randomized clinical trial, subsequent VTE. Future studies to refine optimal dose and duration of anticoagulation to lower the rate of subsequent thromboembolic events and SVT recurrence are needed.
