What Is Superficial Thrombophlebitis?

Superficial thrombophlebitis refers to self-limiting vasculitis of superficial veins of medium size. It often manifests as superficial vein pain, tenderness, induration and / or erythema. High skin temperature and erythema can often touch cords or nodules. It most commonly occurs in the saphenous vein of the lower limb and its branches. It also appears in the veins of the upper limbs, forearm, or neck, and is often caused by varicose veins, hypercoagulability, venipuncture, and administration. SVT generally refers to thrombophlebitis of the lower limbs.

Superficial thrombophlebitis refers to self-limiting vasculitis of superficial veins of medium size. It often manifests as superficial vein pain, tenderness, induration and / or erythema. High skin temperature and erythema can often touch cords or nodules. It most commonly occurs in the saphenous vein of the lower limb and its branches. It also appears in the veins of the upper limbs, forearm, or neck, and is often caused by varicose veins, hypercoagulability, venipuncture, and administration. SVT generally refers to thrombophlebitis of the lower limbs.

Etiological diagnosis depends on the site of the disease. The main cause of SVT in the lower limbs is still varicose veins. Local damage to varicose veins is often a trigger for SVT. In idiopathic, migratory, or recurrent SVT or without varicose veins, it is necessary to determine whether there are other pathological conditions such as autoimmune diseases (especially Behcet's disease and Berg's disease), malignant tumors, and thrombosis Status, including: factor V Leiden gene mutation, prothrombin G202010A gene mutation, heparin cofactor 2 deficiency, protein S and protein C deficiency, antithrombin III deficiency, lupus anticoagulant and antiphospholipid antibody deficiency, fibrinolytic activity Abnormalities, oral contraceptives, hormone replacement therapy, pregnancy, obesity, chronic braking, recent surgery, trauma, sclerotherapy, history of venous thromboembolism, intravenous infusion of hypotonic and hypertonic solutions, use of drugs (including diazepam, amines Iodone, vancomycin, heroin) and intravenous intubation.

The diagnosis of this disease is mainly based on clinical signs, mainly including: pain, tenderness, induration, high local skin temperature, erythema, and / or palpable cords that follow a superficial vein. Use of Doppler ultrasound (DUS) to detect asymptomatic and / or contralateral asymptomatic deep venous thrombosis, confirm clinical diagnosis of superficial thrombophlebitis, and show the great saphenous-femoral vein and great saphenous-iliac vein junction The spread of the thrombus and the location of the thrombus head. It also helps with complex differential diagnoses such as cellulitis, nodular erythema, and lymphangitis.
