Varicose and Spider veins are leg veins which have become
abnormally enlarged. They can protrude or appear flat on the
surface of the skin. The reason they occur is because valves
in the vein stop functioning properly and allow a backward
flow of blood to enlarge and fully weaken the veins. The
enlarged veins can be classified into 1 of 3 general sizes:
1. LARGE TRUNCULAR VEINS � These large veins include the
large and short Saphenous Veins. These divide into the
2. MEDIUM SIZED or RETICULAR VEINS � These usually comprise
a network of blue- green which feed into the spider veins.
3. SMALL SIZED or SPIDER VEINS - These can be blue, red, or
purple. The reticular veins must be treated before the
spider veins. Spider veins on the face can be treated as
well, usually with laser techniques.
Causes of Varicose Veins
The main cause is hereditary (runs in the family). Women are
more prone to varicose veins because of female hormones, and
are especially worse after pregnancy. Age also plays a role
- with increasing age more veins develop. Other less common
causes include: prolonged standing, obesity, whirlpools,
wearing high heels or tight girdles and the use of birth
Symptoms of Varicose Veins
Varicose veins may not be painful at all. Larger veins are
not necessarily more painful than smaller ones. Often it is
the smaller spider veins that cause more discomfort and
burning. Vein symptoms are often worse at the end of the
day, or with menstruation, or pregnancy. The discomfort may
be described as a sharp pain, dull pain, burning, aching
tiredness, or restlessness. Night cramps may also occur.
Treatment Options for Varicose Veins
SURGERY ~ This is the preferred treatment
for the large varicose long and short Saphenous Veins. A
�stripping� operation removes the large veins leaving only a
few small scars. After surgery, Sclerotherapy is used to
treat the side branches even if they are large truncular
veins. There are many large veins the can be treated by
Sclerotherapy thereby avoiding surgery and anaesthesia.
SCLEROTHERAPY ~ This technique is used to
eliminate veins of all sizes. It involves a tiny injection
into the vein causes an irritation of the walls of the vein.
The vein then hardens, and gradually breaks up disappearing
without a trace. A typical appointment lasts approximately
LASER ~ Laser can be used to treat some
veins- usually on the face. Sclerotherapy is still a
superior treatment to laser for leg veins.
What is Sclerotherapy ?
Sclerotherapy is a series of needles given at The Toronto
Vein Clinic, cotton balls are taped to each injection site.
The tapes are important to give gentle pressure to the
treated veins. The cotton balls may be removed 2-3 hours
later. Some bruising may last for several days.
The injections are not very painful, in fact, less painful
then a blood test.
Normal activity can resume right after treatment, but we ask
that you avoid strenuous work/exercise on the day of
treatment. Please avoid prolonged periods of immobility on
the day of treatment such as long naps or long car drives.
Do not schedule any air flights for 2 weeks after your
treatment. Do not schedule any overseas flights for 3 weeks
after treatment. Please check with Dr. Weksberg prior to
your appointment regarding any long flights over 3 hours
Treatments are usually performed every two weeks, and
occasionally weekly. The total number of treatments will
vary between patients, but can be as short as 1-2 visits, or
require over 15 visits. The larger veins are treated first,
then the smaller veins afterwards.
Sclerotherapy will not eliminate hereditary tendency to
develop varicose or spider veins. Patients may therefore
notice some new but different veins in the future. These
should be treated to keep the veins under control. Yearly
follow up and treatment at The Toronto Vein Clinic is
therefore recommended as necessary.
What are the possible Side Effects of Sclerotherapy
Rare side effects may include:
Complications are very rare but may include:
- Small brown patches may occur on spots treated in about 5%
of cases. These will usually fade in several weeks to
months. They are almost never permanent.
- A slightly tender red bump may develop in injected areas.
This is an irritation of the vein from the injected
medicine. There is no need to rest in bed. It will generally
resolve in less than a few weeks.
- Spider veins (telangiectasia) may develop after the larger
veins are treated in about 5% of cases. They usually
disappear by themselves within 4 - 8 weeks. If a few veins
persist these can be treated at a future visit to the
What do I need to do BEFORE my Sclerotherapy
- Skin ulcer healing with a scar (very rare).
- Allergic reactions are very rare. The reaction may be mild
(eg. itchiness) or severe (eg. anaphylaxis or very low
- Deep vein thrombosis (blood clot in leg) and pulmonary
embolism (blood clot in the lung) are very rare.
What do I need to do AFTER my Sclerotherapy Treatment?
- Do not use creams or oils on your legs the night before
and the day of treatment. Using creams or oils interfere
with adherence of the tapes to the skin, and can result in
- Avoid hot baths and whirlpools. These cause further
enlargement of veins.
- Do not shave legs the day before and the day of treatment.
- Try to avoid self tanning creams. The tapes may cause
temporary discoloration of the artificial tan.
After treatments are completed, you would return for several
maintenance treatments at The Toronto Vein Clinic anywhere
between 6 months to 1-2 years later.
- Remove the cotton balls 2-3 hours after treatment. You may
notice sticky �tape marks� on your legs. These can be easily
removed with adhesive remover.
- You may notice small bumps, or darkening of the veins.
This is temporary and should gradually resolve.
- Continue your normal routine. Moderate exercise such as
walking is encouraged.
- If prescribed, wear elastic support stockings or bandages.
- If standing for long periods, remember to tense and relax
your calf muscles periodically to aid circulation.
- Try not to wear tight girdles. They block blood flow
through veins. High heeled shoes also slow the circulation.
