Endovenous radiofrequency ablation is a minimally invasive procedure that treats asymptomatic and symptomatic venous reflux disease. The vein specialists at Palm Vein Center perform this procedure, which was formerly known as the VNUS Closure® procedure but now is called the Venefit™ procedure, under local anesthesia and ultrasound guidance.
During treatment, a physician inserts the Convidien ClosureFAST™ catheter into the diseased vein to begin administering radiofrequency waves. With the help of the ClosureRFG™ (radio-frequency generator), the catheter heats the vein in 7cm segments within 20-second treatment cycles. This causes the vein to shrink and seal itself. Once the vein is sealed, blood will re-route from the diseased vein to healthy veins nearby.
Shortly after the Venefit™ procedure is complete, your vein specialist will apply a small bandage over the insertion site and administer additional compression using various wraps.
Although walking and mild activities are encouraged following the procedure, patients should avoid prolonged standing and strenuous activities. Your vein specialist may instruct the application of compression stockings for at least three weeks post-operatively. To learn more about Endovenous Radio-Frequency Treatment, call Palm Vein Center.
