Approximately 30% of patients with varicose veins will experience an episode of clotting of a varicosity, which is called acute thrombophlebitis. This is usually limited to the superficial venous system and therefore superficial to the muscle layer. In some situations there is the potential for the clot to extend to the deep veins of the leg, a more serious situation.
Symptoms of Phlebitis/Acute Thrombophlebitis
Symptoms of phlebitis/acute thrombophlebitis involving a varicose vein include pain, tenderness, warmth and swelling in the affected area. Anyone suspected of having acute thrombophlebitis should be promptly evaluated. A non-invasive venous colour doppler (ultrasonography of the leg veins) is used to diagnose the condition and assess the extent of the clotting.
