Superficial Thrombophlebitis

Superficial Thrombophlebitis is an inflammatory condition of the veins in the superficial system due to a blood clot. Veins in the superficial system include: great saphenous vein (GSV), small saphenous vein (SSV), accessory and duplicate saphenous veins and tributary branches (also known as varicose veins – when they have become incompetent).  
Your chances of developing superficial thrombophlebitis can be increased due to extended immobility (such as on a long flight); pregnancy; oral contraceptives; venous insufficiency (including varicose veins); a hereditary blood clotting disorder (i.e. factor V Leiden mutation or prothrombin gene mutation), recent IV placement, catheter procedure or injection in a vein.  

  • Redness and swelling  
  • Warmth and inflammation of skin near the vein(s) 
  • Pain or tenderness at the affected area 
  • Darkening and/or hardening along the clotted vein(s).
