Varicose Veins
Varicose veins are the bluish, sometimes purple veins that are
seen and felt near the surface of the skin. They are more common
in women than in men. They result from a reduced rate of blood
flow, damage to the vessels near the skin surface, or impairment
of the valves that control the return blood flow via the venous
system.
Varicose veins may first be noted during pregnancy as a result
of the increased pressure from the baby’s weight as well
as the hormonal changes. Obesity as well as long periods of standing
on one’s feet can also promote their occurrence. A family
tendency for varicose vein development may also be noted.
Leg discomfort may result from the presence of varicose veins.
Although unsightly, they rarely result in any serious consequences.
Among the treatment options is vein stripping or ligation in which
the veins are surgically tied off and removed. This procedure does
involve an approach via incision to access the veins involved and
may result in short-term postoperative discomfort for which analgesics
may be prescribed. Another method is sclerotherapy. This involves
the injection of an agent such as saline that in effect causes
the collapse of the vein and subsequent development of scar tissue.
Spider Veins
Capillaries that burst from increased venous pressure can cause
a surrounding pattern of red vessels on the skin surface. They
also are more common in women and have a family
tendency for development. Spider veins are completely benign with
no consequences. Sclerotherapy and laser therapy are available
treatment options.
