VARICOSE
VEINS
What Are
Varicose Veins?
Varicose veins
are superficial engorged and convoluted veins that appear around
the calves and thighs.
They are unsightly and very common although not a cause for concern
in most people. Varicose veins can also appear in any part of
the body, when veins around the anus become varicose, they are
called Haemorrhoids.
Normally blood
flows through the arteries down the legs and returns back up the
legs through the veins.
The deep veins carry most of the blood to the heart whereas the
less important superficial veins can become varicose. These veins
contain valves, which should allow the blood to flow upwards toward
the heart by the action of the muscles movements of the legs.
Sometimes these valves are damaged, the veins are dilated and
the blood pooled back forming the varicosities in these veins.
Naturally gravity plays a part in making these veins look engorged
and convoluted with prolonged standing or walking and the temporary
relief is lying down or raising the legs up.
What are the causes?
Genetics
-
A history of varicose veins in the family. Varicose and spider
veins can be associated with hereditary factors. About a fifth
of the population have varicose veins
Deep veins
thrombosis -
Occasionally the deep veins of the legs may be involved due to
thrombophlebits (Inflammation of the deep veins)
Occupations
or hobbies. -
Activities that require prolonged standing in occupation such
as - nurses, sales assistants, waitresses, teachers or flight
attendants
Pregnancy
or menopause. -
Hormonal changes during pregnancy, menstruation or menopause may
be contributory factor. The female hormones tend to relax the
vein walls allowing the blood to pool back in the legs.
Obesity.
-
Overweight people are more likely to get varicose veins due to
the added pressure on the legs veins.
Age. -
Varicose veins appear gradually and tend to affect the over 30
and can get worse over the years.
Precautions
to relieve and prevent varicose veins.
Avoid standing
for long periods at a time. Shift your weight from one leg to
the other frequently if your job or hobby requires you to stand
for a long time.
Keep your
weight down through proper dieting.
Keep fit through
exercising regularly.
Do not cross
your legs while sitting down as this prevents the flow of blood
in your legs.
Elevate your
legs while resting to ease the back flow of blood to your heart.
Avoid salty foods to prevent swelling in the legs.
Wear elastic
support stockings or crepe bandage to ease pain or prevent swelling
of the legs.
In long car
journeys stop and take a walk every hour or so. Get up and walk
around in long haul flights.
Signs and
Symptoms
The symptoms may be present before varicose appear. However
the signs and symptoms may include:
- Legs feeling
heavy and achy with or without throbbing and burning sensation.
Swelling and cramp in the lower legs. Prolonged sitting or standing
tends to make your legs feel worse.
- Superficial
distended veins visible under the skin of your legs.
- Discoloration
of skin around the ankles.
- The distended
veins feel itchy.
- Skin ulceration
around the ankles, which represent a severe form of vascular
disease and require immediate medical or surgical attention.
Occasionally,
the deep veins within your legs are involved. In such cases, your
limbs may swell considerably. Any sudden leg swelling that may
or may not be accompanied by pain and redness needs urgent medical
attention, as it may indicate a blood clot (DVT).
If you are concerned about how your veins look and feel after
taking precautionary measures and the conditions are getting worse
then you should see your doctor. If your legs look bad with the
distended veins and you are not having any symptoms, your veins
can be taken out or treated cosmetically.
Diagnosis
When you consult your doctor, he will examine your legs while
you are standing to detect for swelling and to see if the swelling
goes down while you are lying flat with you legs elevated. He
will also ask you to describe the ache and pain in your legs.
An ultrasound test may be required to see if there is evidence
of a blood clot. The skin around your ankles will be examined
for discolouration due to ulceration. Some further tests may be
performed.
Complications
It is sometimes possible to develop very painful ulcers on the
skin near the varicose veins, especially around the ankles. Discolouring
of the skin usually precedes the development of an ulcer, which
may be caused by long term oedema (waterlogging) of these tissues
around the affected veins.
Treatment
Options
There are
several options in treating varicose veins. The most common procedure
is surgery or sclerotherapy. These procedures may be used alone
or in combination.
Surgery
- The veins can be removed by a process known as "stripping",
a procedure in which a thin flexible wire or plastic is passed
into the damaged vein at the ankle or knee level and removed through
a small incision at the groin. The incision at the groin is fairly
small about 2 to 3cm long. The smaller tributaries of these veins
may be removed by different techniques, using of vein hook or
avulsion method without leaving any scars.
