Causes and treatment of varicose veins: 7 ways to improve symptoms
Varicose veins used to be common in the elderly, but due to lifestyle changes, now many young people have the disease, the main reason is long standing and sitting.
Varicose vein is a very slow disease, at the beginning you will feel almost nothing, and even after a period of time, there will not be obvious symptoms and pain, but this does not mean that we should relax our vigilance.
Just as the onset of varicose veins is slow, the treatment of varicose veins is sometimes slow.
What is the reason of varicose vein?
The vein is mainly responsible for the body’s blood back to the heart, because the leg vein is far from the heart, blood flow needs to be assisted by the lower limb muscles, as well as venous valve guidance.
Under normal circumstances, the lower limb blood with the assistance of muscles and valves should be smooth return to the heart, if the venous valve function weakened or atresia incomplete, easy to make too much blood stasis in the lower extremity, thereby increasing the pressure of the lower limb vein. Causing varicose veins.
As shown above, if the venous valve fails to close properly, blood will flow back, causing blood to accumulate.
What symptom or complication does varicosity have?
Varicose veins may not be obvious early symptoms, shanks only fine blue veins, when the lower extremity varicose symptoms, patients may be aware of leg skin itching, edema, leg soreness, easy cramps, leg heavy feeling. In the thigh or calf skin appearance, will emerge spider web, earthworm-like warped blood vessels, with the development of the disease, ankle skin may change color, ulceration.
Serious illness may also lead to complications, such as superficial venous bleeding, may produce inflammatory blood clots and thrombosis phlebitis, the surface will appear swelling, pain symptoms. If the thrombus is free to the lungs, pulmonary embolism may occur with a risk of death.
In addition, the lower limb edema is not necessarily a simple varicose vein, if bilateral limb edema, doctors will consider whether for chronic renal failure, nephrotic syndrome, heart failure, liver cirrhosis, anemia, etc.; if it is unilateral edema of the lower extremity, the doctor will consider whether it is chronic renal failure, nephrotic syndrome, heart failure, liver cirrhosis, anemia and so on. There may also be a risk of deep vein embolism, cellulitis, and gouty arthritis.
People who are prone to varicose veins
The proportion of men and women with varicose veins is about 1:4, which is more likely to occur in women. Excluding congenital factors such as familial inheritance, patients with varicose veins usually have many characteristics, such as long-term pressure on the limbs, increased abdominal pressure, etc., and most of them are related to the work type.
- Congenital factors (such as congenital vascular valve dysfunction)
- Long-term cough
- Frequent constipation
- Often heavy objects (such as porters)
- Prostate hypertrophy
- Long standing, sedentary (such as teachers, chefs, medical staff)
Grade of severity of varicose veins.
Varicose vein is a chronic, progressive vascular degeneration disease, and the differences are quite obvious in different periods. At the beginning, it may only be the microvascular expansion of the skin surface, and then it may lead to severe skin pigmentation, ulcer and so on. The patient can’t ignore it.
Early diagnosis and treatment by vascular surgeons is essential to prevent varicose veins from worsening and complications.
- Stage 1: Spider silk microvasculature.
- Stage 2: typical varicose veins.
- Stage 3: edema of lower extremity or ankle.
- Stage 4: pigmentation of lower extremity or ankle skin, darkening of color.
- Stage 5: the lower limbs appear varicose wound festering, the wound can be treated and recovered.
- Stage 6: varicose veins of the lower extremity of the upper mouth ulceration, the wound can not be treated and recovered.
What are the treatments?
Treatment can be divided into two main principles: if the vessel diameter of the varicose is less than 0.6 cm and the deep meridian system is normal, sclerosing agent, extravascular laser or pulsed phototherapy may be used; if the vessel diameter of the varicose is greater than 0.6 cm, Surgical removal or intravascular laser therapy was assessed by a physician.
(I) sclerosing agent therapy.
Sclerosing agents (such as high concentration of physiological salt water, other agents) injected into the veins of the varicose, in order to damage the intima of blood vessels, blood vessels inflamed and sclerotic, atrophy, a short time may be a case of bruising; It takes about three to five weeks to make a difference.
Patients can be treated at the clinic for about 10-15 minutes. Possible side effects include allergies, local pain, skin necrosis, and pigmentation. Although the safety of sclerotherapy is high, it is not applicable to all patients and should be evaluated by a physician.
(II) extravascular laser or pulsed light.
For small cobwebs of varicose veins, it usually takes several courses of treatment.
(III) Intravascular laser therapy.
In the inner knee to make a incision of about 0.3 cm, and then guided by ultrasound, into a very thin fiber optic catheter, identify the location of varicose vein, laser beam cautery, so as to block the varicose vein blood flow.
(IV) Surgical treatment.
The main surgical methods are as follows: high ligation of great saphenous vein, venectomy, perforated vein ligation, simple venectomy. The main objective of the operation is to remove the varicose veins.
Surgical treatment is not advisable in cases such as local inflammation or infection, bleeding tendency, pregnancy, obesity, deep vein obstruction, peripheral arterial obstruction, lymphedema, etc., if there are other misgivings. Discuss and evaluate with your physician.
How to prevent and improve?
There are several principles to prevent varicose veins, physical principles to promote venous reflux, reduce abdominal pressure, avoid risk factors, if constipation, chronic cough, urethral obstruction, we must seek medical treatment to reduce the risk of varicose veins.
- Wear elastic socks (for venous drainage).
- Moderate exercise (promoting venous reflux).
- Sleep with your feet high (for venous drainage).
- Avoid straining the abdomen (avoid increasing abdominal pressure).
- Avoid sedentary, standing, cross-legged (avoid blood clogging in the lower extremities).
- Control body weight, eat low fat, low salt (reduce abdominal pressure, avoid increasing vascular burden).
- Avoid alcohol and tobacco (alcohol accelerates varicose veins; smoking increases blood pressure and exacerbates varicose veins)
How to choose elastic socks?
Wearing elastic socks is one of the most effective method, the principle of medical auxiliary socks is to use the pressure of the ankle gradually upward decline, mimic the venous return mode, so that the blood flow back to the heart smoothly.
Elastic socks should not be “tight” as the basis for selection, but should consult a doctor to buy, do not randomly choose online shop to buy.
Work must be sedentary or standing for a long time how to do?
In addition to wearing elastic socks, many people have to stand or sit for a long time because of their work. They can also use simple movements to promote blood flow, such as standing up every hour and lifting their legs before going to bed. Or occasionally elevating their legs to help ease varicose veins.
Although not every patient with varicose veins must be treated, if the condition does not improve, it must be diagnosed by a doctor in cardiac vascular surgery in order to avoid a worsening of the condition.
