Veins function to bring blood
back to the heart from the body. Veins have one-way valves that
normally function to keep blood moving only in one direction. When
these valves malfunction, the blood flows backward and dilates the
veins. Spider veins are small red, blue or purple veins on the
surface of the skin. Varicose veins are larger, and somewhat deeper
than spider veins. Varicose veins frequently cause not only cosmetic
problems, but can cause feelings of fatigue, heaviness, aching, and
swelling of the legs. Long standing vein disorders can cause skin
inflammation, and even skin ulcers.
Phlebology is the field of medicine focusing on
the diagnosis and treatment of vein disorders. The American College
of Phlebology was established over 20 years ago in the United States as a
forum for the advancement of this field and is the largest phlebology society in the United States. Its members are physicians
with backgrounds from a variety of medical specialties who share a
common interest and expertise in treating vein disorders.
Phlebology is now recognized by the American Medical Association as
a specialty.
Vein disorders are not always visible. Therefore,
diagnostic techniques are important tools in determining the cause
and severity of the problem. In addition to physical examination,
noninvasive testing may be needed to accurately find the veins that
are not functioning correctly. Handheld Doppler examination is often
done by the evaluating nurse or physician to screen for problems
involving larger veins that are not visible externally. If there is
evidence to suggest this more serious venous problem, a test called
a Duplex Ultrasound may be needed. This sophisticated, noninvasive
test allows the physician to actually see the involved veins and
assess each individual patient in order to ensure that an
appropriate treatment plan can be made.
