Complications
of Varicose Veins
How
do varicose veins present |
1. |
Cosmetic
problems - they look bad but don't feel bad. |
2. |
Localized
discomfort - in the leg, especially after standing.
Usually at the site of a visible varicose vein. |
3. |
Generalized
discomfort - aching and discomfort particularly
at the end of the day. |
4. |
Night
cramps. |
5. |
Acute
bleeding - this can be alarming and even life threatening.
It is treated by putting the leg in the air and
applying pressure. |
6. |
Thrombophlebitis
- an inflammatory condition in which a portion
of a varicose vein becomes red and painful. |
7. |
Damage
to major arteries or veins. This should not occur
when the procedure is done by an experienced vascular
surgeon. |
8. |
Discoloration.
The varicose veins contain blood, which is made
up in part of iron. The iron pigment can lead to
a temporary brownish discoloration of the skin.
This will usually fade over time but can take weeks
to months in severe cases. Most patients state
that they are much happier with the color than
they were with the veins appearance and over time
the discoloration is much better. |
9. |
Development
of the thread veins can occur after venous surgery.
These can be easily treated with sclerotherapy
if needed. |
10. |
Deep
vein thrombosis. This is rare in healthy patients
having uncomplicated varicose vein surgery.
|
|
If
varicose veins are due to damage to the deep veins, then
they may cause itching, brown discoloration round the
ankle, swelling of the leg and large ulcers. The latter
may last for years and be very resistant to treatment. |
|
Venous
Ulcers, Venous Eczema, Venous Skin Changes: When
the venous system in the leg fails to work normally
the pressure in the leg veins rises. This reduces the
circulation in the lower leg particularly around the
ankle leading to swelling, discomfort, skin changes
and eventually ulceration. Varicose veins are the commonest
cause for this.
Eczema
& Skin Changes: A
form of eczema can occur in the calf, sometimes over
an area of varicosity. The skin is red and itchy. Areas
of the calf and around the ankle may develop a brown
stain in the skin. The ankle area may be prone to swelling
towards the end of the day. Sometimes the entire lower
leg feels tight and hard, and may look red and inflamed.
This may be acute lipodermatosclerosis (LDS) due to
the high venous pressure or an infection (cellulitis).
Ulcers: There
are many theories to explain why the raised pressure
in abnormal leg veins leads to skin problems. The skin
becomes vulnerable, and is poor at healing. A small injury,
bite, or minor infection, which would normally heal,
instead progresses, and an area of skin breakdown results.
This is called an ulcer. In the presence of venous disease,
the term Venous Ulcer is used. |
Treatments
|
Non
operative treatment: Patients with varicose
veins usually request treatment for two reasons:
a) cosmetic or
b)
because the varicose veins are causing
problems. |
1. |
Compression
stockings: These can relieve symptoms, hide veins
and slow down deterioration of skin changes. They
need to be worn every day - summer and winter.
Many people find this irksome. Stockings need to
be replaced every six months since they wear out.
They need to be graduated - with the highest pressure
at the ankle, dropping to 75% at the calf and 50%
at the thigh. Most people only need the below knee
stockings which are easier to wear than full length
ones.
Indications:
a) |
Varicose
veins developing during pregnancy. |
b) |
Patients
who have varicose veins but don't want or
are unfit for surgery. |
c) |
Patients
with secondary varicose veins. |
|
2. |
Sclerotherapy: This procedure involves injecting a sclerosant
solution into varicose veins. This irritates the
inside of the vein wall which is then compressed
with a bandage which cause the wall to stick together and obliterate the lumen
( that part through which the blood flows) of the vein. Sclerotherapy is easily
done in the consulting room without anesthetic. Bandages remain on for 10 days
to 2 weeks and patients are encouraged to walk for about an hour a day until
next seen at the clinic. Sclerotherapy is usually around Rs5000/- per session,
per leg.
Sclerotherapy has fallen out of favour for treatment of larger veins because
of almost 100% recurrence at 4-5 years after the procedure.
Most vascular surgeons feel that patients with incompetence of the long and short
saphenous veins and their major branches should have surgery instead of sclerotherapy
since the recurrence rate is less.
Indications:
a) |
The
sclerotherapy works well for patients with
isolated varicose veins and thread veins.
It is less satisfactory for short veins above
the knee than below the knee, since they
are more difficult to compress. |
b) |
Complications
of sclerotherapy include - discoloration/skin
pigmentation in the injected site ( this
usually fades ) and mild pain in the injected
vein (usually requiring paracetamol for
a week or two). Most people can go back
to work the
next day. |
|
3. |
Surgery: Most varicose vein surgery can be done as
day surgery or short stay surgery. It can be done under
general,
regional or local anesthetic. I prefer the former
two methods.
Following surgery I prefer to keep a compression bandage
on for 48 hours. This can be replaced by a stocking
until the first clinic visit one week later, and then
dispensed with. Following surgery patients can walk,
carry on with their social activities, go shopping
etc. Driving can be undertaken once there is no groin
tenderness. Surgery is associated with very little
pain or tenderness. Most patients can commence work
4-5 days after surgery or less.
For patients with long saphenous vein incompetence the standard procedure involves
a small groin incision. The long saphenous vein is tied off and divided from
the femoral vein (together with surrounding branches ). It may then be stripped
down to just below the knee (under the skin) or not. The varicose branches
(which are premarked before surgery) are avulsed through a series of stab incisions
about 2-5mm in length. The lesser saphenous vein is similarly dealt with except
that the incision is behind the knee where this vein drains into the popliteal
vein. |

EVLT
: Laser Treatment for Varicose Veins: A
new technique - endovenous laser ablation is
now available. This involves passing a laser
catheter
up the long saphenous vein. The laser catheter
is then activated and slowly withdrawn down
the vein.
This heats up the inside of the vein wall causing
it to stick together thus obliterating the inside
of the vein. This procedure avoids a groin incision.
Stab incisions are however still necessary. Patients
can be back at work after 36 hours.
This procedure is similar to the radio frequency
ablation procedure which was done in the 1990s,
in that heat
is used to close the veins. No long term follow ups
for this procedure are available but as for the RFA
procedure which had a fairly high recurrence rate,
my personal opinion is that we can expect the same
from this as well. In our experience, we do not recommend
this procedure to a patient who is fit for surgery
as we have seen patients recur within a few months(3-6)
of having done the procedure. So apart from the high
costs involved the recurrence rate is also higher.
As is a natural phenomenon, the body tries to clear
any injury or blocks within itself and laser & RFA
are basically damaging the vein, and the body tries
to heal the damage. The other drawback of this procedure
is that it does not treat the perforator veins which
most people just treat with sclerotherapy - after
having done laser treatment to the main vein in the
thigh
-which as you already know has a 100% recurrence
rate at 4-5 years.
In my opinion the best and long lasting results for
varicose vein treatment are by surgery which has
to be carried out after a thorough color Doppler
examination & any
other required investigations, of the venous system
of the leg.
Thread veins. These can occur on their own or in association
with long or short saphenous vein incompetence. In
the latter case the main superficial vein incompetence
should be dealt with surgically. Then the thread veins
can be injected. This may involve several treatments.
Thread veins can also be treated with laser therapy
but this may also involve many treatments and may also
leave areas of skin pigmentation. |
