Spider veins - broken capillaries that leave a road map of red and purple lines on your skin - can ruin the looks of a great pair of legs. Although they're primarily a cosmetic problem, not a medical one, spider veins afflict about 40% of women and 10% of men.
Once they're there, exercise and good nutrition won't get rid of them. But Sclerotherapy can. Sclero what? Sclerotherapy, a method of treating varicose veins and spider veins. Refinements in this traditional treatment promise faster, more effective and less painful relief. And
laser therapy, still in its infancy, may someday replace the traditional treatment. But let's start at the beginning: Spider and varicose veins are similar hut not related. Both are caused by "extra" blood in the legs.
In the case of varicose veins, they are caused by rerouting of blood from the major leg vein, the saphenous vein, to other smaller veins. (MI veins in the body carry blood to the heart - arteries carry blood away from the heart, for use throughout the body.) When the valves of the
saphenous veins are weakened by age, genetics, pregnancy, too much standing or sitting, too little exercise, etc., these veins cannot return to the heart all the blood that was delivered to the legs. The result is too much blood in the legs, and smaller veins must handle the flow.
Ill-equipped to handle the excess, the veins bulge under the pressure. The result is varicose veins.
Spider veins are close to the skirfs surface, also bulging because of extra blood. But unlike varicose veins, which are beneath the skin, spider veins are "tiny capillaries on the surface of the skin," explains SM. Green- stone, MD, vascular surgeon in Encino, California, Spider
veins are not the result of rerouted blood - they just appear. "We don't really know why," says Greenstone.
They just do, but one factor seems to be heredity - if your mom's got 'em, you probably will too. What's more, pregnancy often leaves these unsightly traces because heightened estrogen levels during pregnancy weaken vein walls. (Not to mention the pressure on the legs from additional
weight.) Birth control pills, with their estrogen-raising effect,can also induce spider veins. Athletes are at no special risk unless they have a family history of varicose and spider veins. Genetics is the key.
All a woman can do is keep a keen watch and then start looking into cosmetic surgery. The oldest treatment for varicose veins is surgery, called "vein stripping." Here, the defective valves of the saphenous veins are surgically removed, leaving scars where the bulging veins once
were. Even today when varicose veins are larger than 3-4 millimeters in diameter, surgery is the only effective option.
