In clinical practice, there are no sequelae after varicose vein surgery. However, patients after varicose vein surgery may experience complications related to the surgery. The related complications include the following: First, the surgical incision bleeds, and then the patient’s surgical incision must be pressurized and given sutures to stop the bleeding if necessary; moreover, the patient may also develop a subcutaneous hematoma, and then an elastic bandage should be used to put pressure on the lower limbs. Patients may experience numbness after surgery, which is caused by the damage to the patient’s dermal nerve during the surgery, and generally after 3 months of compensation, the patient’s numbness will improve. Third, patients may form deep vein thrombosis after surgery. Generally speaking, surgical trauma may easily lead to deep vein thrombosis, and then patients must be treated with anticoagulation therapy. In clinical practice, anticoagulant drugs often used include low molecular heparin sodium, warfarin, rivaroxaban, dabigatran, etc. Therefore, it is important to pay attention to the complications associated with varicose veins after surgery so that the patient can recover healthily.
