Varicose veins are almost always associated with venous reflux. This occurs when the valves in the leg veins don’t work well, and backward blood flow causes pooling in the lower leg. Without treatment, the pressure this creates may increase over time and cause additional varicose veins and symptoms. People with a family history and who are older, obese or are pregnant may be at increased risk of developing varicose veins.
It is unclear if varicose veins can be prevented, but certain actions may help limit the disease’s progression and symptoms. Routine exercise, maintaining a normal weight, avoiding excessively long periods of standing or sitting, and the use of compression stockings may all help alleviate symptoms.
The term ‘varicose veins‘ is often used to describe everything from smaller, spider veins (red or blue veins on the surface of the skin) up to true varicose veins (swollen, bulging veins with a rope-like appearance). Varicose veins are quite common, with one in three woman and one in five men experience problems. Varicose vein symptoms can include swelling, tiredness, heavy feeling, leg fatigue, leg pain, as well as burning and itching sensations.
Spider veins are small veins near the skin surface and appear as webs of blue, purple or red. Heredity is a significant contributing factor in the development of spider veins. Other predisposing conditions include excessive sun exposure and prolonged standing. Spider veins may also be a sign of an underlying malfunction of the larger leg veins. In this case sclerotherapy may be required to achieve satisfactory results. While surface laser and sclerotherapy are effective at closing the veins present at the time of treatment; neither of these procedures stops the body from making new spider veins. Thus, over time, additional treatment may be required to maintain the cosmetic appearance. Spider veins are generally considered a cosmetic issue and medical treatment is not required.
Sometimes the same factors that helped to cause your first spider veins or varicose veins (e.g., family history, age, obesity, female hormones, etc.) will make you predisposed to develop additional vein conditions. If a specific vein is properly treated, it usually does not recur, but it is possible that other veins may become diseased. This is why it is important that even if you have what appear to be simple, cosmetic spider veins, that you consult a vein specialist who can determine if you have an underlying condition (venous reflux). If you do, and you don’t treat the cause of the problem, additional spider veins or varicose veins are likely to develop.
If you have underlying venous disease (e.g., venous reflux), the pressure created by backflow of blood and pooling in the lower legs may create a progressive condition that only gets worse with time. This may lead to additional spider veins and varicose veins, and in some cases can lead to swelling and venous ulcers at the lower calf and ankle. Only a trained vein specialist can effectively evaluate your spider veins or varicose veins.
Procedures like VNUS Closure/Venefit and ambulatory phlebectomy, when shown to be medically necessary, are commonly covered by Medicare and insurance providers. Sclerotherapy for spider veins is generally considered a cosmetic procedure and usually not covered. Consult your local insurance provider to determine your exact eligibility and coverage as well as cost.
Procedures like sclerotherapy and Closure act to close down a faulty vein. The vein being closed is dysfunctional and is allowing blood to flow backwards and pool, so leaving it open only makes things worse. The body contains numerous other healthy veins that are still functional and can easily take up the additional flow. Treatment of the faulty veins almost always results in improved blood flow in the overall vein system.
