Venous Insufficiency Treatments with laser (EVLA, EVLT, EVL) and the Varithena Procedure
Endovenous laser therapy (EVLT), also known as EVLA (endovenous laser ablation) can be done on truncal veins (great or lesser saphenous) or incompetent veins which directly feed networks of reticular and varicose veins which distribute into networks of spider veins (tips of the iceberg). EVLT/EVLA therefore treat 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.

Varithena is another option to chemically ablate saphenous veins for saphenofemoral venous reflux.
Varithena was approved by the FDA in November 2013 - it shows 80% success in closing saphenous veins - versus > 95% for the "gold standard" ablation techniques such VNUS Closure and EVLT/EVLA (98%). Varithena foam is a promising technique that awaits long term outcome studies.
