The procedure is performed on an outpatient basis.
Using ultrasound, your physician will position the catheter into the diseased vein, through a small opening in the skin. The tiny catheter delivers radiofrequency (RF) energy to the vein wall. As the RF energy is delivered and the catheter is withdrawn, the vein wall is heated, causing the collagen in the wall to shrink and the vein to close. Once the diseased vein is closed, blood is re-routed to other healthy veins.
Following the procedure, a simple bandage is placed over the insertion site, and additional compression may be provided to aid healing. Your doctor may encourage you to walk, and to refrain from extended standing and strenuous activities for a period of time. Patients who undergo the procedure typically resume normal activities within a day.
The new generation VNUS ClosureFASTTM catheter delivers controlled radiofrequency energy and monitors treatment temperature for the purpose of closing diseased veins. The procedure reduces treatment time and minimizes post-procedure pain and bruising.
