The prevalence of varicose veins in the lower extremities is about 7% 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 the pressure in the veins, causing them to dilate and twist over time, which is called varicose veins. In the past, it was thought that asymptomatic varicose veins or elderly patients could be treated conservatively, including medication or compression stockings. However, medicine has advanced to the point where more and more varicose vein patients are opting for early minimally invasive surgical treatment. First of all, medications 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. Although elastic stockings are effective, they need to be worn for life and are troublesome and costly to use. The development of medicine has also made the surgery of varicose veins in lower limbs more and more minimally invasive. The adoption of minimally invasive surgery has shortened the hospital stay from a week in the past to just two days, and you can go home in just a few hours. However, minimally invasive surgery is only suitable for early varicose veins. As elderly patients age, their general condition deteriorates. If they do not undergo minimally invasive surgery in the early stages and later develop complications from varicose veins, they are often unable to treat them 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. In summary, the drawbacks of conservative treatment of varicose veins are: 1. side effects of medications; 2. reduced quality of life with the use of compression stockings (e.g. too hot in summer, hard to wear, need to buy new stockings every 6 months); 3. risk of progression of the disease and loss of the opportunity to choose minimally invasive surgery. 4.Once complications occur, the recurrence rate and failure rate of surgery increases significantly. 5.Lose the purpose of leg beauty after surgery. Although varicose vein surgery has a certain recurrence rate, but even if recurrence happens, it is much better than the case of complications without surgery.
