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.
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.
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.
Procedures like sclerotherapy, EVLT 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.
Procedures like EVLT, Closure and vein stripping, 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.
There is a newer physician specialty called phlebology which focuses on vein treatment. This specialty has its own society (American College of Phlebology), provides board certification and specialty training. Consult with your individual physician to determine whether they have any such specialty training or certification.
