Lymphoedema

1. What is lymphoedema?
|
Lymphoedema is swelling which is due to a build up
of fluid (lymph) in the leg. Normally this fluid drains out
of the leg via a network of tiny tubes (lymphatics).
In your case the fluid is not draining out properly. To start
with the swelling is often noticeable at the end of the day
and goes down at night. However, unless the swelling is treated
properly, the fluid becomes fixed in the leg permanently. |
|
2. What causes lymphoedema?
|
| The most common cause for lymphoedema is that the lymphatics have been damaged. This is usually after surgery
that involves the lymph glands. Another cause is scarring of the
lymphatics after infections in the leg.
Rarley some people are born without enough lymphatics. If there are very few
lymphatics then the swelling may start as a teenager or even
earlier. This type of lymphoedema is called Milroy's Disease.
One leg is often worse than the other and sometimes only one leg
is affected.
In less severe cases the lymphatics may be able to cope
initially and only start to fail when you are older. This kind
is sometimes called Lymphoedema Tarda.
|
|
3. Are there any other causes?
|
Lymphoedema can also be caused if the lymphatics
of the arm and leg are damaged by radiotherapy for
the treatment of cancer. Sometimes this is unavoidable if the
cancer is to be cured.
There are also some rare tropical parasites (Filariasis) that
invade and block the lymphatics. These parasites do not live in
Great Britain. |
|
4. What effects does lymphoedema have?
|
| Apart from the uncomfortable and unsightly
swelling, lymphoedema can cause problems, especially if it is
not kept under control. There is an increased risk of infection
under the skin (cellulitis) and repeated attacks of cellulitis
lead to more lymphatic damage. This viscous circle may
eventually lead to severe infections, ulcers and even amputation
in extreme cases. |
|
5. What is the treatment?
|
Lymphoedema cannot be cured but it can usually be
controlled so that complications do not occur later. The
mainstays of treatment are compression bandages or stockings,
elevation of the limb, external pneumatic compression and the
early use of antibiotics if infections occur.
Elevation of the limb. Whenever the
leg is elevated, fluid will tend to drain out of it. Put your
legs up whenever you can and as high as you are able - the
arm of a sofa is good. Elevate the end of your bed (6 inches or
so) in order that your feet are a little higher than your head.
You can use some old books for this. It may be more comfortable
to put a pillow on the books and rest the back of your calf on
it.
Compression bandages or stockings.
Compression is required to squeeze the fluid out of your legs
when you are standing up. Bandages may be required at first, to
remove the worst of the swelling, before stockings can be used.
These stockings need to be specially fitted and are much
stronger than ordinary "support tights". If the
swelling only affects the lower leg, then you can wear a
below-knee stocking that is self-supporting, like a pop-sock.
The usual strength of stocking used is a Class II, but sometimes
a stronger Class III is required. If you have difficulty putting
on your stockings, then you can buy a special stocking
applicator. Mr Braithwaite can provide these stockings for you
as an NHS prescription.
External Pneumatic Compression (EPC). Despite
compression stockings, many people find that some swelling
accumulates by the end of the day. The EPC device is a pneumatic
boot that inflates and deflates to squeeze fluid out of the leg.
EPC is normally used in the evening to get rid of any fluid that
has built up despite compression stockings. If your Mr
Braithwaite thinks you need EPC therapy, a trial of the device will normally
be arranged so that you can decide whether it is worth buying
one. Mr Braithwaite can often get a discount on the price of the
compression device.
Antibiotics. When the lymphatics
have been damaged, any infections of the skin of the leg can
take longer to get better or can become more serious. It is
therefore wise to avoid getting cuts or scratches on the legs.
If you do get cut and the wound becomes red and painful, it is
probably best to ask your doctor for some antibiotics.

|
6. What about surgery?
|
| Many operations have been tried to cure
lymphoedema, but none have been successful. Surgery to reduce
the size of the lower leg (Homan's Reduction) may be suggested
if your leg remains very swollen despite compression therapy. Mr
Braithwaite has been trained to perform this operation but would
only recommend the procedure in severe circumstances. |
|
7. How can I help myself?
|
- Wear your compression stockings every day from morning to
night.
- Elevate your legs whenever possible.
- Take plenty of exercise and don't put on weight.
- Keep the skin in good condition by using plenty of
moisturising cream to prevent dryness.
- Ask for antibiotics at the first sign of infection to
reduce the risk of further damage to the lymphatics.
