Chronic lower-inal varicose veins are a common disease in about 10-35% of adults with slow, non-aggressive progress, which is much more hindering for living and work, when the disease causes complications of intravenous ulcers that are difficult to treat.
The disease is more common in women than in men with a ratio of 3:1, the diagnosis of the disease is not too complicated but the most long-term and expensive treatment is when complications have occurred.
1. What is chronic lower vein varicose veins?
This is a deterioration of the function of the lower vein system due to insular valve failure of the a shallow venous system or deep vein system that may be accompanied by venous embolism. At this time, the blood returned to the heart will weaken causing stagnation in the veins of the legs. When the vein is stagnant and dilated due to pathology, there will be an abnormal variation in the anatomy, characterized by dilated degrees greater than 3mm, if encountered in small and shallow veins, it is easy to form varicose veins of the cobwebs, mesh form.
2. Mechanisms that cause varicose veins of the lower veins
Normal blood in the legs will be returned to the heart thanks to the following 3 mechanisms:
● Thrust in the leg while walking
● Suction generated when breathing
● The valve system in the heart of the vein helps prevent blood from reflux down
Therefore, if one of the above 3 mechanisms is limited, the blood will not return to the heart, leading to stagnation of blood in the veins of the feet causing varicose veins of the lower limbs.
3. Causes of varicose veins of the lower veins
Causes of development:
● Iedostatic varicose veins: due to genetic or hemolytic abnormalities of the shallow vein system
● Worm veins: due to anortomical abnormalities such as the free bank of the valve is too long, causing valve dismissal or valve dility
● Post-thromboembolysis syndrome
● Intravenous malformation: is a congenital deficiency or mitigation of intravenous valve production (shallow or deep), intravenous malformations with or without arterial fistula
● Due to compression such as tumors, Cockett syndrome
● Hemolysis such as pregnancy, sports.
4. How to diagnose varicose veins of the lower veins?
Diagnosis of varicose veins of the lower veins through the symptoms of the patient is as follows:
At the initial stage:
● Faint symptoms, patients often present with leg pain, leg heavier or sometimes just a tighter-than-usual feeling of wearing footwear
● Don't sit a lot prone to leg fatigue or mild edema
● Cramps at night
● Deformity feels like needle stinging, ants crawling in the legs at night
● The smallest blood vessels are in the ankle and foot areas that emerge.
Stage of progress:
● Patients with edema of the legs, edema in the ankles or feet
● The skin color of the shin area changes due to blood stagnation in long-term veins causing dysenteritis
● Bulging veins, clearly floating causing severe sensations, soreness, not losing at rest
● Bruised blood patches on the skin.
Stage of complications:
● Aortic venous inflammation of the thrombophlitis causes deep veinembolism, pulmonaryembolism, which can be life-threatening
● Varicose veins cause severe bleeding
● Ulcer infection of chronic vein failure.
● Doppler ultrasound: seen with inverted blood flow, thrombosis
● Intravenous imaging with contrast pumps is performed only when the existence and characteristics of reflux currents in the vein system are not accurately identified.
5. Lower-entered varicose veins according to CEAP
Degree 0: not visible or palpable middle vein
Level 1: Have a stretched capillaries or a stretched vein mesh, size <3mm.
Level 2: Varicose veins are large, visible, >3mm in size.
Degree 3: Edema but not yet modified on the skin.
Level 4: Dyseritis.
Degree 5: Dysmenile of the skin and scarring of ulcers have healed.
Degree 6: Progressive skin dysmatitis and ulcers.
6. How to treat chronic lower veins?
● Prevent reflux and make the forces that act on the flow of the veins better such as: leaving your feet high at rest, exercising strong muscles, avoiding standing or sitting for too long, wearing elastic socks or rolls with elastic bandages, pressure socks, avoiding malformations, obesity and maintaining a high-fiber diet to avoid constipation
● Use of vascular endurance drugs such as daflon, rutin C but only works in the early stages of varicose veins is mainly.
Less invasive intervention:
● Refrigeration method with 90 degree negative liquid nitrogen to choke the vein through a cathex in the vein. However, this method has a recurrence rate of up to 30%
● High frequency wave embolizing: is a method of thermal tissue destruction caused by the friction of ions in the tissue aimed at eliminating the reflux blood flow in the large visible vein usually applied to patients with varicose veins of 2nd degree or higher according to CEAP resolution , medical treatment does not improve.
Stripping surgery, Chivas surgery: are methods to remove dilated shallow veins with specialized tools. The Stripping technique will allow the withdrawal of the veins while the Chivas method will take the dilated veins of the piercing system. This is the treatment with the lowest recurrence rate.
At Share99 International Health Hub, there is a package of examination of lower veins to help customers with symptoms of the disease be examined in depth to clearly identify the condition of the disease.
