Radio Frequency Electrosurgery
Radio Frequency Electrosurgery uses heat generated from a radio frequency electric current to
damage and close the greater saphenous vein from inside, much
the way microwave ovens heat food. Radio frequency
procedures can take 90 minutes to two hours to complete, double
the time needed for EVLT™. With EVLT™, the actual vein
sealing takes approximately three minutes, while the time
needed during radio frequency procedures is 25-45 minutes.
Radio Frequency electrosurgey is not recommended for veins
larger than 12mm in diameter and may therefore not be
appropriate treatment for some patients. EVLT™ on the other
hand has no such restrictions and limitations. |
