Pre-operative preparation: fasting and water fasting before surgery, skin preparation of the surgical site, attention to rest, avoid excessive tension. 2. Anesthesia: Traditional varicose saphenous vein surgery needs to be carried out under anesthesia, common anesthesia methods include lumbar anesthesia combined with epidural anesthesia, and some patients adopt general anesthesia, which should be carried out in accordance with the anesthesiologist’s medical advice. 3. Surgery: incise the skin and subcutaneous tissue in the femur, find the varicose saphenous vein, ligate the trunk of the vein in a high position, and then peel off the segments of the side branches of the saphenous vein, suture each incision, and the whole lower limb is wrapped with an elastic bandage to prevent bleeding from the peeled area. 4. The whole surgical process will be finished when the patient returns to the hospital room after the postoperative resuscitation. After the operation, pay attention to the cleanliness and dryness of the surgical incision, change the medication regularly, closely observe whether there is any blood seepage, whether there is any swelling of the lower limbs, etc., and inform the doctor promptly if there is any discomfort.
