Phlebitis, also known as thrombophlebitis, can usually be cured, but it is determined on a case-by-case basis. Phlebitis mainly includes thrombosed superficial phlebitis as well as thrombosed deep phlebitis. Superficial thrombophlebitis is usually treated with topical medication, such as Jinhuang San, and is usually cured, with medication administered under the direction of a doctor. Whether thrombophlebitis can be cured or not can be influenced by many factors. Most of the patients can be cured by anticoagulation, thrombolysis, mechanical suction of thrombus or surgical extraction of thrombus from deep veins, but some patients are not suitable for surgical treatment, and the cure is more difficult. If DVT is in a stable state, there will be no serious consequences if it is not cured. However, some patients may develop post-thrombotic syndrome, in which edema of the lower limbs, varicose veins, hyperpigmentation, and ulcers remain after many years of the disease. Therefore, when phlebitis occurs, it is necessary to actively consult the doctor and follow the doctor’s instructions for reasonable treatment.
