The Venefit procedure, formerly known as the VNUS closure procedure, is a minimally invasive medical treatment for varicose veins that involves using a radiofrequency ablation catheter to close diseased leg veins. The procedure is usually performed in a doctor's office or outpatient clinic under local anesthesia, according to Venefit.Continue Reading
During the Venefit procedure, a small incision is made below the knee, and a special catheter, called the ClosureFast catheter, is inserted into the vein, states Venefit. The doctor uses ultrasound imaging to guide the placement of the ClosureFast catheter, which delivers 20 second bursts of radiofrequency energy to the diseased vein. The heat from this energy causes the vein to collapse and close. The Venefit procedure typically takes 45 to 60 minutes. After treatment, blood flow continues through the remaining healthy veins, and the treated vein is eventually absorbed by the body.
Most patients can return to normal activities a few days after the Venefit procedure. Although most patients experience minimal side effects after the procedure, bruising, tenderness, swelling and scarring may occur, according to Venefit. Some doctors suggest that patients engage in a walking program, avoid performing strenuous activities and refrain from standing for long time periods for several weeks after the Venefit procedure.Learn more about Diagnostics & Imaging
