About Vascular Procedures
Varicose and spider veins are common and cause a variety of symptoms
in
both men and women. It is estimated that 80 million Americans are
affected
by spider or varicose veins (41% of women ages 40-50). This percentage
increases with age. The symptoms caused by varicose and spider veins
range from a cosmetic nuisance to an aching, heavy sensation, to
a painful
condition that limits enjoyable activities and even the ability to
work. The
most severe cases can lead to ulcers forming on the legs.
Spider Veins
Spider veins appear as red or purple sunbursts on the skin surface
and
can occur on the face, legs or ankles. They can ache or itch
and can be
found alone or in combination with varicose veins. Spider veins
are not a
health risk alone, but are often a cosmetic concern.
Varicose Veins
Veins normally function to return blood to the heart. Valves in
the veins close
after blood travels up the vein, preventing blood from backing
up or refluxing
down the vein. Valves can become abnormal or incompetent for a
variety of
reasons, including trauma, pregnancy or hereditary factors. Once
a valve
becomes incompetent, the vein below the valve is exposed to higher
pressure
and can then dilate. Other veins and valves nearby are exposed
to the higher
pressure and can also dilate. Varicose veins commonly appear on
the legs
as raised, often ropey enlarged veins. They can cause the legs
to swell, throb,
and in severe cases cause inflammation, ulcers and blood clots.
