Restless Legs and Venous Reflux Disease
Venous insufficiency and Restless Legs Syndrome (RLS)
Venous reflux disease, also known as venous insufficiency can cause restless legs, and in some patients, the Restless Legs Syndrome (RLS).
In a recent study done in Texas, a cohort of patients who had restless legs syndrome were investigated by venous Doppler and determined to have venous reflux disease. They were randomized to receive 1) endovenous ablaion of the great saphenous vein with laser or 2) no treatment with endovenous laser.
Endovenous obliteration of the great saphenous can be performed with VNUS Closure or endovenous laser therapy (EVLT, ELVeS, EVL - all synonyms). VNUS Closure uses radiofrequency energy to ablate the vein.
In patients with RLS and venous reflux disease of the great saphenous vein, symptoms of RLS resolved following endovenous obliteration of the great saphenous vein. The authors concluded that patietns with RLS should be investigated with a venous Doppler to determine if they have venous reflux disease before they are initiated medical therapy.
