Chronic Venous Insufficiency
(CVI): Its Causes & Treatment
Chronic Venous Insufficiency (CVI) is a condition where veins do
not efficiently return blood from the limbs back to the heart. It
may occur following excessive blood clotting (such as deep vein
thrombosis) and leg veins inflammation. It can also result from
the failure of the vein valves to close properly and to hold blood
against gravity. In this condition, sluggish movement of blood from
the veins result in swollen legs, crampings and the feelings of
dull achiness and/or heaviness ("heavy leg" or "tired
leg" syndrome).
CVI is a common problem in the United States - it is estimated
that up to approximately 5% of Americans or 15 million people have
chronic venous insufficiency. CVI affects mostly older people, especially
older women.
What are the Causes of Chronic Venous
Insufficiency?
In a normal leg vein, the flow of blood from the legs to the heart
is facilitated by a series of valves on the inner vein walls. These
valves open to permit the flow of blood to the heart, but close
to prevent blood from flowing back to the lower limbs.
Failure of these vein valves to close properly can cause blood
to leak backward into the leg, in a condition called venous insufficiency
or chronic venous insufficiency.
There are many conditions that lead to vein valve failure, including
blood clots in the deep vein (deep vein thrombosis) and varicose
vein. Risk factors of CVI includes genetics or the inherited tendency
of vein valves to fail, old age, extreme inactivity, obesity, diabetes
mellitus, and heart disease. Hormonal changes, such as those that
occur during pregnancy, certain forms of vein cancer, as well as
injury can also lead to CVI.
What are the Symptoms of Chronic Venous
Insufficiency?
The symptoms of chronic venous insufficiency include:
- Swollen feet, ankles, and calves
- Dull aching and pain, especially after a prolonged period of
standing
- The feeling of "heaviness" or tiredness of the leg
(leg fatigue)
- Burning sensation
- Cramping or charley horse
- Itching
- Flaking of the skin
- Skin discoloration and darkening
- Leg skin that looks and feels leathery
- Spider veins, reticular varicosities, and varicose veins
- Ulcers or sores, in some advanced cases of CVI
The first sign of CVI is usually swelling in the leg and ankle.
This swelling occurs because pooled blood cause abnormally high
pressure in the veins. As the pressure increases, vein and arteries
in the lower limbs may leak tiny drops of plasma, causing a pale
yellow discoloration. Capillaries may also break, giving the skin
a localized reddish brown discoloration. If scratched or bumped,
discolored skin can break, often resulting in ulcers or sores, which
subsequently can become infected.
In some instances, stasis or pooled blood can also cause a symptom
of Restless Leg Syndrome, where the person has an irresistible urge
to move the leg, especially at night.
As listed above, venous insufficiency can also result in enlarged
veins, either small (spider veins), medium (reticular varicosities),
or large (varicose veins).
Treatments of Chronic Venous Insufficiency
Treatment of chronic venous insufficiency includes:
 |
Elevating Your Legs and Peforming
Leg Exercises
For mild and early cases of chronic venous insufficiency,
elevating your feet above your heart level whenever you are
sitting or lying down can help the pooled blood to drain.
Elevate your leg for 15 to 20 minutes about 4 times daily.
Unless you are obese, or suffering from heart disease and
hiatal hernia, you can also elevate the foot of your bed approximately
9 inches to help blood to drain during the night.
Avoid long periods of sitting or standing. If you are taking
long flights, remember to flex and extend your legs, feet,
and ankles about 10 times every 30 minutes to facilitate blood
flow in the veins. |

Compression Stockings
Compression or elastic stockings work by squeezing the vein
and helping to keep the blod flowing away from the extremities
of the limb and back to the heart.
These special stockings have varying or graduated pressure
along the height of the leg, with tighter fit at the bottom
of the leg. This is because the ankle and calf veins are under
greater pressure than the rest of the leg veins and need more
support.
Stockings do tend to give quick relief from chronic venous
insufficiency symptoms. However, they have the following drawbacks:
- It does not cure chronic venous insufficiency, and the
symptoms may get progressively worse over time.
- If improperly fitted, elastic stockings can cut off circulation
to the lower legs.
- These stockings need to be worn all the time and can get
uncomfortable throughout the day.
- Specially fitted stockings can be expensive and need to
be replaced about four times per year.

Prescription Cream
To alleviate the itching and cracking of the skin, your doctor
may prescribe an anti-itch cream containing hydrocortisone
and moisturizer. To prevent infection, he may also prescribe
a zinc oxide cream or an anti-fungal cream.
For skin sores, compression bandages can be applied to protect
the skin and promote blood flow. For infected ulcers and cellulitis,
antibiotics are prescribed. |

Vein Surgery
Depending on the position and depth of the vein, various
forms of vein surgeries can be performed to unblock blood
clots that form in the vein, bypass faulty veins, as well
as to repair faulty vein valves. |

Herbal Supplements
Studies have shown that various herbal supplements can be
used to naturally treat chronic venous insufficiency. These
herbs include:
Japanese pagoda tree
(Sophora japonica)
Studies
have shown that Japanese pagoda tree extracts, with the
active ingredients of rutin bioflavonoids, can improve vein
wall tone and strength, increase microcirculation, reduce
swelling, improve elasticity, and fix vein permeability.
Numerous clinical studies, involving more than 2,000 patients,
have shown that Japanese pagoda tree extract can provide
substantial relief from the swelling, aching, leg pains,
and other discomforts of CVI.
Horse chesnut (Aesculus
hippocastanum)
Horse
chestnut has been used for many decades as an herbal preparation
for various vein conditions. It has been shown to reduce
inflammation and improve the vein wall tone to facilitate
blood flow back to the heart. It is thought to fix microscopic
leaks in tiny veins and capillaries, as well as reinforce
the strength of the vein walls and promote their elasticity.
A 1996 study involving 240 patients showed that horse chestnut
extract is just as effective as elastic stocking in providing
relief from the swelling and pain of varicose veins and
chronic venous insufficiency.
Butcher's broom (Ruscus
aculeatus)
Butcher's
broom extract has been used for many years as a traditional
medicine for treating vein disorders. In the 1950s, studies
on Butcher's broom discovered that it can strengthen and
tone veins, as well as lessening swelling and inflammation.
In treating chronic venous insufficiency as well as varicose
veins, butcher's broom has been found to relieve not only
leg pains, but also swelling, itching, numbness, cramping,
and the "heavy" sensation in the leg.
