METHODS OF
TREATMENT
There are
several methods by which varicose veins can be treated.
The specific procedure or combination of procedures
recommended is based upon the severity of the condition.
Some treatment options include the following:
Laser:
In some cases, underlying vein disease may be treated
with an advanced ultrasound guided laser technique
through a single puncture or an incision that is less
than a quarter of an inch. Sometimes referred to as
endovenous laser or "endolaser", this approach allows
treatment of vein disease that in the past required
stripping through large incisions. Our many years of
experience with ultrasound guided vein therapy makes us
uniquely qualified to offer this advanced ultrasound
guided laser method to our patients. This procedure can
be performed in the office.

Conservative Treatment:
Special support stockings are prescribed to slow
down the progression of varicose veins. This is done for
symptomatic relief, but they must be worn pretty much
every day for the rest of your life to be effective.
Stockings may help vein symptoms so long as they are
worn, but they do not cure the problem.
Sclerotherapy:
Sclerotherapy is performed by injecting a solution into
the diseased veins. . A mild chemical solution is
injected into the dysfunctional vein,
which causes it to
shrink and gradually disappear. A single treatment
session may involve as few as 1 to as many as 50
injections. After treatment, the leg is wrapped in
elastic bandages to ensure that the treated veins remain
closed. Sclerotherapy does not require anesthesia, and
can be done in the doctor's office. Side effects
which may only occur at the site of the injection, such
as stinging or painful cramps; red raised patches of
skin, small skin ulcers, and bruises. Spots, brown
lines, or groups of fine red blood vessels could appear
around the vein being treated. These usually disappear.
The treated vein could become inflamed. Applying heat
and taking aspirin or antibiotics can relieve this.
Lumps of coagulated or congested blood may develop which
are not dangerous and can be drained.
Foam sclerotherapy
Instead of using a sclerosing agent in its liquid
form, this technique involves a foam sclerosing
solution. The principle behind foam sclerotherapy is the
same one that makes shaving cream so effective: foam has
a greater surface area than liquid, which increases the
likelihood that it will cling to its target surface.
Foam sclerotherapy irritates the vein and causes it to
shrink more quickly than liquid sclerotherapy.
"No-Stitch" Micro-Surgical Procedures:
These procedures are used for surface varicose veins
that are too large to be easily treated by sclerotherapy.
The incisions are only 2-3mm (about an eighth of an
inch) and are so small that they do not require
stitches. Advanced micro-surgical procedures such as
ambulatory phlebectomy are performed in the office with
mild sedation and leave no large scars.
Image Guided Ligation
Ligation may be needed to treat deeper vein disease
in some patients who cannot be treated by other methods.
Unlike older "blind" surgery requiring larger
exploratory incisions, the surgical site is localized
using ultrasound imaging and a small incision is made,
usually 1 to 2 inches long. Ligation is usually
performed in combination with injection sclerotherapy
and/or micro-incisional removal of surface varicose
veins.
Surgical Ligation and Stripping
Surgical stripping is reserved for only the most severe
10% of varicose vein cases. It is usually used to remove
the main superficial vein (the long saphenous vein),
which runs from the groin to the ankle. This collects
blood only from the skin. Removing the veins will not
affect the circulation of blood in the leg because veins
deeper in the leg take care of the larger volumes of
blood. Vein stripping" is the oldest method for
treatment of varicose veins. The first surgery was first
performed 100 years ago. Incisions are made to dissect
down into the leg and locate underlying diseased veins.
Long "strippers" of various designs are passed through
these deeper veins and then the stripper and vein are
pulled out of the leg together. This is almost always
performed using general anesthesia (with the patient
completely unconscious and connected to a ventilator)
due to the tissue trauma involved. The need for general
anesthesia requires that the surgery be performed in a
hospital or equivalent surgical facility. Surface
vessels are commonly removed at the same time through
several incisions measuring 1 to 4 inches each. Recovery
times vary widely, but are typically about two to four
weeks. Some surgeons perform stripping as an outpatient
surgery, with the patient going home at the end of the
day, but others will keep patients hospitalized
overnight or for a day or two.
The 2 main types of surgery for varicose veins are:
1. Mini-phlebectomy
2. Ambulatory surgery.
Mini-phlebectomy is an in-office surgical procedure
performed under local anesthesia to remove the faulty
area of a vein through minute incisions.
Ambulatory surgery is performed in the hospital to
remove the long saphenous vein through two small
incisions at the groin and at the ankle or knee
SIDE EFFECTS
-
Surgery can leave
permanent scars.
-
Serious side effects are
uncommon
-
However, with general
anesthesia, there always is a risk of cardiac and
respiratory complications.
-
Bleeding and congestion
of blood can be a problem, but the collected blood
usually settles on its own and does not require any
further treating.
-
Wound infection,
inflammation, swelling and redness can occur.
-
A very common
complication is the damage of nerve fibres around the
veins which can lead to pain.
