The prevalence of varicose veins in the lower extremities is about 10% in the population. The main pathogenesis of varicose veins in the lower extremities is the incomplete closure of the valves of the saphenous vein into the deep veins, which leads to backflow of blood and increases venous pressure, causing dilated and tortuous veins, called varicose veins. Varicose veins usually occur first in low places, such as the lower legs. Varicose veins can develop for several years, even years, without obvious clinical symptoms. But this does not mean that varicose veins are not harmful. As the disease progresses, complications such as intravenous thrombosis, aseptic inflammation (phlebitis), hyperpigmentation, ulceration, bruising dermatitis, and rupture and bleeding can occur. In the past, the idea was that asymptomatic varicose veins or elderly patients could be treated conservatively first, including medication or compression stockings. This view has a certain universality and is based on considerations such as high surgical trauma, high economic burden, and surgical risk in the patient’s advanced age, which is also justified. However, medical development today, the answer to the question of whether “early surgery or first conservative treatment is better for varicose veins?” The answer to this question has undergone a subtle change. More and more varicose vein patients are opting for early minimally invasive surgical treatment. First of all, drugs and compression stockings, as the main means of conservative varicose vein treatment, can only delay the progression of the disease but not treat the root cause of varicose veins. Therefore, drugs can only be used as an adjunctive treatment after varicose vein surgery in the lower extremities. And although elastic stockings have a definite therapeutic effect, they do not cure, but only delay the further development of the disease. At present, the vast majority of patients who initially wear compression stockings eventually opt for surgery. The time and effort spent on conservative treatment is wasted, since surgery is eventually required. Advances in medicine have also made surgery for varicose veins in the lower extremities increasingly minimally invasive. The adoption of minimally invasive surgery has reduced the length of hospitalization that used to take a week to less than three days. One of the consequences of the development of varicose veins is that as the blood from the deep veins flows back into the opening of the diseased saphenous vein, it flows backwards into the superficial venous system, creating an ineffective circulation that aggravates the burden on the deep veins and, over time, causes or aggravates the degree of deep venous valvulopathy. The severity of deep vein lesions is an important factor in the chance of recurrence after varicose vein surgery. Once the condition reaches thrombophlebitis, swelling of the lower extremities, skin pigmentation, bruising dermatitis or ulcers, the effectiveness of surgery is greatly diminished. For example, surgery does not eliminate the darkening of the skin, surgery is very ineffective for edema, and surgery is less than 80% effective for bruising dermatitis. Phlebitis also takes a long time to subside. In elderly patients, the general condition of the patient deteriorates with age. If they do not undergo minimally invasive surgery in the early stages and develop varicose vein complications later, they often cannot be treated because they cannot tolerate the surgery. Therefore, in order to avoid these complications, the best option is to have early surgery to resolve varicose veins before complications arise.
