Varicose veins

What are varicose veins?
Varicose veins are
twisted, enlarged veins, near or raised above the surface of
the skin often dark blue in color. Varicose veins are often
a symptom of an underlying condition called venous
insufficiency.
Varicose veins do not occur suddenly. It usually takes years
for symptoms to develop. Varicose veins are commonly
inherited, although it is important to note that anyone can
get them. Often times varicose veins are common in people
that have had certain types of leg injuries or deep vein
blood clots. Varicose veins also become more frequent as
people work standing still or sitting down. These activities
deprive veins of regular circulatory flow of the leg muscle.
In healthy veins, one way valves direct the flow of venous
blood upward and inward. Blood is collected in superficial
small veins and flows into larger veins. The blood
eventually passes through valves into the deep veins and
then centrally to the heart and lungs. When one or more of
these valves fail to function correctly or leaks, some blood
flows down the leg, in the reverse direction. The blood
tends to overfill and distend the branches of superficial
veins under the skin.
Deep veins can withstand
this pressure because of their construction and because the
surrounding conforming muscle prevents the veins from
becoming excessively distended. Over time, this additional
venous blood pressure causes the veins to stretch, bulge,
and become visible. Continued exposure to high pressure can
cause superficial veins of any size to become dilated and
twisted.
When valves fail, blood will accumulate under pressure
causing swollen, engorged or rope-like veins. These are
varicose veins, which are abnormal. These veins have become
weakened and fill up with blood. The valves inside these
veins no longer close allowing blood to leak back down the
leg producing a distention of the vein. Varicose veins are
common, affecting mostly women
What
are the different treatment options?
-
Sclerotherapy is a technique,
which involves the use of a very fine needle to inject a
solution (sclerosant) directly into the veins. The
solution causes the lining of the vein swell, eventually
sealing off the blood vessel and preventing blood flow.
Prior to treatment, a complete medical history is taken
and a thorough examination made in order to determine,
among other things, how long the problem has existed,
the severity of the symptoms, whether or not the
condition is affected by physical activity, and if there
has been prior surgery or treatment of the veins. The
physician determines if the deep venous system is
affected, in which case surgery may be recommended
before sclerotherapy is undertaken. Preoperative
instructions may include the elimination of certain
drugs, which contain aspirin in order to minimize the
possibility of excess bleeding. The physician decides
whether or not the area to be treated should be shaved.
The veins are usually marked while the patient is in a
standing position.
Larger veins are usually treated first. After the skin
is thoroughly cleansed with alcohol, the physician uses
a syringe with a tiny needle to inject a small amount of
sclerosing (hardening) solution directly into a vein.
The solution displaces the blood within the vein,
causing it to blanch or turn white. The solution then
causes the vessel to become irritated and swell shut,
prohibiting the blood from reentering the vein. When the
needle is withdrawn, pressure is immediately applied to
the area. The skin may be kneaded to help disperse the
solution and reduce bruising. Each vein may require
several injections and most disappear in two weeks to
two months.

Endovenous laser therapy is a
quick, minimally invasive laser procedure is an
alternative to vein stripping and leaves no scar, has a
short and relatively pain-free post-operative recovery
period, and is performed under local anesthesia in the
doctor's treatment room. The treatment itself will take
less than one hour and initially involves both a
physical and an ultrasound examination to map the vein
to be treated.
The area of the leg affected is anesthetized locally and
a thin laser fiber is inserted into the abnormal vein,
delivering the laser energy in short pulses. The laser
energy heats the vein causing it to shrink and collapse,
preventing blood from pooling.
Walking immediately following the procedure is
encouraged and normal daily activity can be resumed
immediately. However, strenuous physical activity such
as aerobics should be avoided for one week. Patients may
experience bruising and soreness for 3-5 days after the
treatment. Pain is usually improved by walking or oral
pain relief medications.
We are excited to share
that we have achieved spectacular results using this
non-surgical alternative to vein stripping surgery. The
obvious advantages to this procedure:
1)
In office procedure
2)
Done under local anesthesia
3)
Patients can resume activities of daily living and
work the next day.
4)
No scarring since there are no incisions, other than
one needle mark.

Until recently, vein ligation and
stripping was the standard for treating larger or
perforating varicose veins. If the majority of the
valves in the vein are healthy, ligation can be used to
isolate the faulty valves and the remaining vein may be
left in place to continue circulating blood. If the vein
is heavily damaged it is usually removed, or stripped.
To strip a vein, an incision is made below the damaged
vein and the vein is grasped and surgically removed.
Most people are able to return to their normal daily and
recreational activities within a few weeks. Some common
side effects from vein stripping and ligation surgery
may include temporary pain or discomfort, bruising,
hematoma, numbness, and less frequently wound infection.
Vein stripping is an invasive procedure and should not
be performed on older individuals for whom surgery poses
a risk due to other medical conditions. It is also not
an appropriate choice for people who have circulatory
problems of the legs, skin infections, blood-clotting
defects or an abnormal passageway between and artery and
vein. Pregnant women are also inappropriate candidates
for vein stripping.
Who should not be treated?
Patients should wait at least three months after pregnancy
or major surgery before being treated for vein disease.
Patients who have suppressed immune systems, persons with
deep vein thrombosis or incompetence and patients who cannot
ambulate for other reasons are not good candidates for
treatment.
If the vein is closed by the treatment, where does the
blood go?
Because there are many veins in the leg, the blood that
would have flowed through the closed vein simply flows
through other healthy veins after the procedure. The loss of
the diseased vein is not a problem for the circulatory
system.
What can happen if varicose veins aren't treated?
Varicose veins generally worsen over time. Initially, slight
pain and restlessness in the diseased leg will be felt. If
untreated, this pain will increase and result in limitations
in walking and cramps during sleeping. Eventually, varicose
veins can lead to open sores on the foot, blood clots and
tissue loss.
What are the complications of vein treatment?
Fortunately, sclerotherapy and Endovenous laser therapies
have rarely been associated with any serious complications
when properly performed. Common minor complications of these
procedures include bruising, mild itching, tenderness and
tightness in the treated leg for up to two weeks after the
treatment.
Will insurance cover the treatment?
Most insurance companies cover the treatment of vein disease
that is associated with substantial pain and other
complications. Each insurance company has its own rules for
the types of therapy that are covered.
