Non-surgical
Very basic advice should be given to everyone with venous disease
prior to contemplating surgical treatment. This includes:
Exercise
Elevation of legs when resting
Loss of weight
Support stocking – these are readily available either on
prescription or over the counter. Many chemists will measure your
leg for you to ensure proper fitting. The stocking provides a
gradient of pressure from ankle to knee (or higher) which
facilitates the muscle pump and flow of blood up the leg. They may
reduce the symptoms suffered, they may prevent further progression
of venous disease and can occasionally improve the appearance of the
ankle in more advanced cases.

Surgical
Treatment of abnormal veins is dictated by their size and also the
results of the duplex scan. Smaller dermal thread veins or those
small varicose veins without a specific feeding vessel may be
treated with injection sclerotherapy or laser. Newer techniques are
currently under evaluation (foam injections).
More severe varicose veins often require surgery. The basic
principle of surgery is to correct the major reflux within the
superficial veins and then to remove the varicose veins.
Conventional and more innovative techniques now exist to correct the
underlying reflux but the visible varicose veins are removed through
a series of small cuts (phlebectomies) within the leg. Reflux within
the perforating veins can be corrected using telescopic surgery
beneath the main fascia. New techniques for varicose vein surgery
are now available and include radiofrequency ablation (VNUS) which
appears to shorten the recovery time, reduce postoperative pain and
reduce the incidence of wound infection.
Injection sclerotherapy
Smaller varicose veins can be treated effectively by injection
treatment providing the reflux within the larger veins is not
present or has been previously treated. Many patients undergoing
superficial vein surgery may notice an improvement in their thread
veins but this cannot be guaranteed and they may occasionally become
worse. More commonly this technique is now used for cosmetic thread
veins.
A sclerosant (chemical) is injected into the veins with very fine
needles. The sclerosant irritates the lining of the wall causing it
to become inflamed. The walls stick together and the vein is
prevented from reopening.
The effects of treatment are not immediate. The inflammation can
affect the immediate adjacent tissues leading to brown staining of
the skin or ulceration. Allergies to the sclerosant are very rare
but may limit the number of treatments that can be offered to a
patient. The small veins can thrombose and this may rarely involve
the larger veins. Generally speaking the veins are more prominent
and inflamed for the first month after injection. The appearance
then subsides over the course of the following 2-3 months but
improvement can still be observed in some patients for up to 1 year
after treatment.
Treatments last approximately 30 minutes with you lying on a couch.
Most people tolerate the procedure with little discomfort. A
stocking or support bandage is provided for the first 48 hours after
treatment.
Other techniques are being used for the treatment of thread veins
including laser and Veinwave. Evidence is still accumulating as to
their overall efficacy and safety with injection therapy remaining
the current gold standard.
Surgery
Conventional surgery has changed significantly over the last decade
due to the specialisation of vascular surgeons and the increasing
availability of the duplex scanner. Techniques have become more
refined and this has improved early recovery and the long term risk
of recurrence of the varicose veins.
Surgery will be guided by the duplex scan and may involve an
operation in the groin with stripping of the long saphenous vein or
an incision behind the knee and partial stripping of the short
saphenous vein. Subfascial endoscopic perforator surgery (SEPS) may
also be offered to correct abnormalities identified within the
perforating veins.
Surgery may be performed as a day case or inpatient depending upon
the severity of the venous disease and proposed length of surgery. A
general anaesthetic is commonly used supplemented by local
anaesthetic to make the wounds numb immediately after surgery. Your
legs are wrapped in support stockings to help reduce postoperative
swelling, bruising and thrombosis. A gentle return to normal
activities is sensible over a 1 –2 week period. Complications are
rare but include bruising, bleeding, infection, sensory
loss/numbness of the skin and recurrence of the varicose veins.
Recurrence can be reduced significantly by good surgical technique.
