I. What is varicose vein of lower extremity?
Generally speaking, varicose veins in the lower extremities refer to simple saphenous varicose veins, where the venous blood backs up into the lower legs to form dilated and tortuous veins due to saphenous vein valve insufficiency.
Second, why do varicose veins occur?
There are three reasons for this.
1, the upper part of the saphenous vein is damaged by incomplete closure of the anti-reflux valve;
2.Long-term standing work (such as teachers, salesmen, surgeons) causes slow venous reflux;
3, congenital weakness of vein wall
Third, what is the effect of varicose veins of lower limbs on people?
Although the development of this disease is slow, but long-term untreated will also appear: 1.
1.Soreness and swelling of the lower limbs, and even difficulty in walking;
2.Warm rash and itching in the lower leg for a long time;
3, calf ulcers for a long time does not heal, and eventually amputation;
4.Venous rupture and bleeding.
Fourth, simple varicose veins of lower limbs should be distinguished from which diseases.
There are many diseases that can also show varicose veins of lower limbs to be distinguished
1, lower limb deep vein obstruction, superficial vein compensatory varicose.
2.Deep vein valve insufficiency;
3.Iliac vein compression caused by pelvic tumor;
4.Obstruction of inferior vena cava;
5.Congenital hemangioma (such as K-T syndrome)
V. What is non-surgical treatment and what are the methods?
Non-surgical treatment, also called conservative treatment, is suitable for
1.The varicose vein with small scope and light degree;
2.Women during pregnancy;
3.Poor general condition that cannot tolerate surgery;
4.Limited residual varicose veins after surgery.
VI. What are the methods of non-surgical treatment?
1.Medical circulation-driven elastic stockings are the most simple and effective conservative treatment method, but elastic stockings can only limit the development of the disease and cannot cure it.
2.Oral medication to promote venous reflux, such as mai zhi ling, etc.
3.Local sclerotherapy injection for dilated veins can only be suitable for small area.
7.When should varicose veins of lower limbs be treated surgically?
As long as the diagnosis is clear, there are clinical symptoms and obvious signs of varicose veins, and the body can tolerate the surgery, all should be treated surgically, and only surgery is the root solution.
VIII. What are the surgical methods?
1.The traditional surgical method for more than 100 years is? Saphenous vein high ligation, saphenous vein trunk pumping calf varicose vein multi-point incision stripping.
2, in recent years with the development of technology there are many minimally invasive surgical methods: such as lower limb vein endovenous laser treatment lower limb vein radiofrequency treatment and so on. These two methods just need to open a small incision of 2cm at the root of the thigh, ligate the saphenous vein trunk, and then insert the laser fiber or radiofrequency closure catheter into the thigh vein from the distal end, then the varicose vein trunk can be closed in situ, and the branches will disappear, which is less traumatic, less painful, faster recovery, and beautiful limbs after surgery.
Nine, why varicose veins in the calf, to open at the root of the thigh?
The superficial veins of the lower leg flow back into the femoral vein from the saphenous vein at the root of the thigh. Most of the varicose vein patients cannot close the valve of the saphenous vein at the confluence into the femoral vein, which causes the backflow of blood, so the gate must be closed tightly to control the rising water.
X. What are the advantages of laser and radiofrequency treatment?
Both are the latest methods of minimally invasive surgery to treat varicose veins in the lower extremities, which do not require multiple incisions to strip the veins and do not extract the trunk. Using laser or radiofrequency can close the dilated veins in situ, with less trauma, less bleeding, faster recovery, fewer incisions and beautiful postoperative appearance, which is more in line with young women’s love of beauty.
Eleven, why should we continue to wear elastic stockings after surgery
Because when the superficial vein is drawn out by surgery, the traffic branch connected with the deep vein is torn off, and if it is not compressed, it will bleed, hematoma or even recur.
The endothelial destruction of the saphenous vein treated by laser radiofrequency needs to be compressed for a period of time to make the lumen of the vessel close and disappear, so the surgery or minimally invasive surgery needs to wear medical elastic stockings for 2-3 months after the surgery.
