Varicose and Spider Veins
What
are spider veins? What are varicose veins?
Spider veins are also known as broken capillaries.
Spider veins are tiny blood vessels no more than 2 mm in diameter
that may appear on the face, legs and ankles. They are bluish, purple
or red and often form a web-like netting just below the skin’s surface.
Spider veins are generally just an unattractive nuisance, although
when they become large they can cause heaviness in the legs, night
cramps and itching.
Varicose veins are veins near the surface of the skin
on the legs which have become permanently distended and filled with
blood. Veins have valves that are designed to prevent blood from flowing
backwards due to gravity. When a valve malfunctions or vein walls
weaken, blood collects in the vein, forcing it to bulge. Varicose
veins are unsightly, bluish or purple in color and can protrude from
the leg. They may cause discomfort such as swelling, throbbing, heaviness,
night cramps and long-term complications such as ulcerations or bleeding.
What
causes them?
For both varicose and spider veins, heredity
is the main cause. The risk of developing these leg vein problems
increases for women who are pregnant or using birth control pills
because hormones such as estrogen can further weaken vein walls. Obesity
and lack of exercise which weaken the system of leg veins are also
factors. The risk of developing varicose veins increases with age
for both men and women.
The "second heart" is a system of muscles,
veins and valves in the calf and foot that work together as a pump
to keep blood moving toward the heart against gravity. This system,
though strong and capable of carrying tremendous weight and pressure,
has a weak link: the venous (vein) system. Like the heart in our chest,
the second heart keeps healthy through regular exercise.
How
can I help prevent them?
Almost 80 million women and men in this
country alone experience leg vein problems, including half of the
women over the age of 40. Once spider and varicose veins develop,
however, there is no way for the body to cure them. Fortunately, there
are simple ways to prevent these problems from spreading and alleviate
symptoms. The sum of these preventive measures is referred to as the
conservative approach. Wearing support stockings with compression
is the most common type of conservative treatment. Regular exercise
promotes healthy circulation within the second heart and also slows
the development of new varicose and spider veins. Diet, lifestyle
changes, dietary supplements, and other natural alternatives can also
compliment the conservative approach. There are other things you can
do to promote good leg vein health, including:
- Avoid birth control pills
- Eat a high fiber diet to prevent constipation
- Don’t wear tight clothes
- Elevate legs at bedtime (about 6 to 12 inches above
the heart)
- Explore natural alternatives, such as massage and
dietary supplements (vitamins C &E may help relieve swelling
and other symptoms of poor circulation)
- Avoid crossing your legs
Following these measures is the best defense against
the spread or development of these vein problems. If you are at risk
for developing either spider or varicose veins, start these conservative
and preventive measures soon.
What
are the medical treatment options?
Medical treatment options restore venous
circulation to its proper functioning by removing varicose and spider
veins and rerouting blood to healthy vessels. Cosmetically, these
medical options are best at eliminating existing spider and varicose
veins. Some methods eliminate varicose and spider veins by collapsing
the affected blood vessel, while other techniques remove a vein through
surgery.
Non-surgical options include sclerotherapy, a painless
way to get rid of these vein problems by injecting a chemical into
the affected vein to close it. Laser therapy can also be used to collapse
small veins in the face and legs. Duplex-guided sclerotherapy is used
to access veins in areas that are difficult to reach such as in the
knee and groin. Surgical methods include in-office mini-phlebectomy
where small sections of the damaged vein are removed through an almost
invisible incision. For ambulatory surgery, there is a procedure called
ligation and stripping to treat the affected main leg vein and valve.
Both non-surgical and surgical treatments are often combined for the
best results.
Although reopening of treated veins is uncommon, problematic
veins may appear in other areas. Return visits for treatments are
usually required every 1 to 3 years. Since most of these procedures
are deemed cosmetic, most insurance companies will not cover the related
costs. It is therefore important for anyone considering treatment
to contact their insurance company.
