Venous Disease
Varices name derives from the Latin word "Varix" which means "shapeless, twisted."
General:
Varicose veins are twisted, enlarged, placed under the skin surface. Most often they develop in the legs and ankles.
Cause:
Varicose veins are usually enlarged, which develop just below the skin (superficial vein). Factors leading to the appearance of varicose veins are:
- Increased pressure on leg veins
- Damage to the leg veins
- Damage to the vein valve (anatomical structures do not allow blood flow only in one direction) feet.
Often, venous disease is a familial disease. Are people born with defective valves or venous walls thinner and these changes may develop later in life. Hormonal changes that occur during puberty, pregnancy or menopause, as well as with administration of estrogen, progesterone pills, all contribute to the emergence and development of varicose veins.
More rarely, venous disease may be a sign of problems or associated diseases that often require treatment: among these diseases are:
- Thrombus (blood clot with fibrous organization) that completely blocks obstrueaza or deep veins or perforating veins (veins of small arms that connect the superficial and deep veins of the legs)
- Damage to the deep veins
- Abnormal blood vessels that connect arteries and veins (arteriovenous fistula). These anomalies may be present since birth or may develop later during the life
- Tumors (rare).
Symptoms:
Venous disease can be completely asimptomatica.Appearance of varices veins is usually recognized by viewing the patient through venous cords twisted, swollen, blue, just below the skin surface. If symptoms occur, they tend to be mild and may include:
- A dull ache, a burning sensation or heaviness in the legs, symptoms are amplified during the day or after long periods of standing or sitting
- Slight swelling, usually only in the foot and ankle
- Pruritus (itching) skin over the veins.
Symptoms may worsen or complications may arise such as:
- Gambia edema (fluid accumulation and swelling in the leg tissues consequent member)
- Significant inflammation and pain in the calf after long periods of sitting or standing - changes in skin color (pigmentation of stasis) around or above the ankle
- Dry skin, stretched, swollen, itchy and exfoliate (removal of skin stratum corneum) in the veins
- Superficial thrombophlebitis (development of a thrombus and the occurrence of inflammation in the small veins, close to the skin surface)
- Open wounds (venous ulcers)
- Bleeding and / or bruising after minor injuries in the foot.
Superficial thrombophlebitis
Are inflammatory, usually circumscribed and abacteriene, subcutaneous veins of the walls, accompanied by adherents clot formation. Deep vein thrombosis compared with their importance is small, they are almost never fatal, they tend to heal spontaneously, although occasionally may extend to deep veins may be septic (effusion), rather than let a exceptionally disabling sequelae.
Incidence of superficial thrombophlebitis is not known, but occur more frequently in some situations, especially varicose veins, veins cateterizate after intravenous administration of irritants. Sometimes revealing the systemic diseases that easing them.
Symptoms:
Superficial vein thrombosis inflamed and appears as a strong cord, painful pressure, traction or spontaneous, more irregular or varicose monoliform if flebitelor with edematiate usually nearby tissues and skin supraiacente erythematous and warm. Edema is always located at flebitic process, a diffuse edema distal to obstruction, is another cause and may be due to an associated DVT.
General phenomena, such as fever and tachycardia, are generally absent or not caused by thrombophlebitis, but the disease, only in rare cases, as in isolated suppurated flebitele flebitele varicose extensive general has an origin due to local phenomena.
Inflammatory phenomena disappear spontaneously within a few days or weeks and often leave behind them a merciful and painless cord, which may be definitive, and a brown-yellow pigment which disappears with time. The veins are likely to recur, especially if the cause persists causing thrombophlebitis. Embolism are practically absent and never fatal in themselves.
Varicose ulcer
Since the blood lacks oxygen in veins is not transported beyond the exchange of nutrients and toxic byproducts impiedicat.From this cause is because the cells are seriously affected, and the tissue dies.Chronic wounds (leg ulcer) may result from such injuries.Type of chronic wound healing finding is related to their varicose veins cause.
Heredity
Weakness of the valves that usually causes varicose veins is often hereditary, along with other vascular diseases. This has a major impact especially on women because female hormones, they are responsible for the fact that most ladies have a very weak connective tissue, which provides very little protection against detente veins. And men are affected by hereditary factors resulting in vascular diseases.
Age
As we age, vein walls lose elasticity and presents a greater risk of varicose devices and vascular disorders.
Lack of exercise
Freeze or sitting for long periods of pumping motion decreases muscle strength, leading to stagnation of blood in their legs and excessive swelling. Long journeys by car, train or plane can make a big enough pressure on the veins. Periodicals bending your ankle can help to pump blood from the legs to the heart (simulating walking). During long periods of standing or below your ankles flexed 10 times and repeat every 10 minutes.
Shoes with high heels or platform
They obstruct blood flow, leading to long term diseases of veins, like varicose veins.
Tight clothes
Again, these clothes can restrict blood flow and may hasten the appearance of varicose veins.
