EVLT can be done on truncal veins (great or lesser saphenous) or perforator veins which directly feed networks of reticular and varicose veins which distribute into networks of spider veins (tips of the iceberg). EVLT therefore treats venous insufficiency and if venous insufficiency is treated, there is less venous hypertension, which seems to be the cause for the development of varicose veins, reticular veins and spider veins. Read the Atlas of Venous Insufficiency and EVLT procedures on the link below.
The answer is "yes", since correctly done EVLT eliminates a condition called "venous insufficiency", which is reponsible for development of the spider veins. The above is true, if ALL incompetent veins are identified and if ALL of them completely closed. It will not only prevent formation of the new spider veins, but alos will help with some of the existing ones. To judge completeness of EVLT you can by behavior of your symptoms: they should be all gone by the end of the treatment. Hope it helps. Good luck.
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.
Varicose veins and ,often times, spider veins are due to leaking (refluxing) valves of usually the saphenous system of veins. If the valves are refluxing then these are usually closed by laser or RF followed by treating the varicose and spider veins. Think of your veins as if they were a tree with the trunk being the saphenous veins with the refluxing valves and the branches being the varicose and spider veins. Treating the branches will not help if the problem is in the trunk. Having said this, however, not all spider veins are due to refluxing valves. Also, spider veins are a chronic problem and there is no permanent solution. Spider veins require long term maintenance once they are under control. You should see a vein specialist for a full venous evaluation.
