Does EVLT work to prevent future spider veins?

Spider veins and varicose veins are often associated with reflux or backwards flow in larger veins that transmit pressure to the smaller veins causing them to enlarge.  An ultrasound evaluation can determine which of these veins are affected. Treatment with EVLT of these larger veins eliminates the source of pressure and makes it less likely to develop complex spider and/or varicose veins in the future.  The smaller veins that are already there should be treated with sclerotherapy after EVLT for the best results.

Thank you for your question. Typically after EVLT the occurrence of new spider veins tends to lessen. Dr. Daniel Ritacca

Hi RQ.  Theoretically yes.  EVLT should improve the overall cardiovascular health of the legs which in turn should help prevent future spider veins.  With that said, the condition that causes spider veins and varicose veins is not being "cured".  Rather you are getting better and trying to maintain your current situation.  You will see deterioration of the vascular system again as you age and this can lead to more varicose or spider veins.If the vessels are small (spider veins) you have options like sclerotherapy and (external) laser treatments.  Good luck.
