Endoluminal catheter-based procedures enable venous reflex in varicose saphenous veins to be eliminated. The catheter tip is positioned in the sapheno femoral or popliteal junction under ultrasound guidance. The energy necessary to ablate the vein is generated as heat by high-frequency current (radiofrequency) by laser light or by steam. Advantages of this procedure include low invasiveness, subcutaneous infusion anesthesia (SIA), low perioperative morbidity and rapid restoration of mobility of patients.
