Varicose veins of the lower limbs with deepened skin color are caused by superficial varicose veins of the lower limbs, which are often treated by high saphenous vein ligation and stripping and minimally invasive interventional surgery. 1. High saphenous vein ligation and stripping: the traditional surgery for varicose saphenous veins, separating and ligating the saphenous vein into the deep vein, and then using the vein stripper to strip the saphenous vein trunk from the body is a kind of complete treatment, with a low recurrence rate after the surgery, but more traumatic. 2. Currently the more advanced minimally invasive interventional treatment modalities, such as laser surgery, radiofrequency ablation, etc., intervene the guidewire from the venous catheter, and then burn the wall of the vein through a certain amount of microwave and thermal energy to completely close the vein. This procedure is less invasive, has a quicker postoperative recovery and a lower recurrence rate. It should be noted that when there is no relief or aggravation of the symptoms, one should visit the hospital in time for examination and treatment under the guidance of the doctor. The specific choice of clinical surgery should be chosen after communication with the doctor.
