Varicose veins can have multiple manifestations. In this article, we will only talk about the operation process of lower extremity varicose vein surgery, including preoperative preparation, intraoperative operation, and postoperative operation. 1. Preoperative preparation: For patients who need varicose vein surgery, they need to fast before surgery. Under color ultrasound localization, the doctor will mark the walking range of varicose veins on the legs. Pre-operation requires intralesional anesthesia, disinfection, toweling and other treatments. 2. Intraoperative operation: The key to varicose vein surgery is the ligation of the root of the saphenous vein, and the doctor will first choose an appropriate incision according to the patient’s condition. Then five small branches are found at the root of the saphenous vein, and these five branches and the root of the saphenous vein are ligated respectively. Finally, a stripper is inserted to strip the entire vein. For small varicose veins on one side or back of the calf, spot stripping, or local puncture for sclerotherapy, laser coagulation or radiofrequency ablation can be performed. 3. Post-operation: After the procedure, the surgeon will wrap the patient’s leg with an elastic bandage to coagulate the veins to avoid bleeding from the stripped veins, the vascular bed or the soft tissues. You can usually get out of bed the next day or the day after the operation. The stripped saphenous vein is an auxiliary structure of the venous system of the lower limbs and does not affect the limb function of the patient’s lower limbs, so the patient does not need to worry about it.
