Radiofrequency ablation is a minimally invasive procedure that uses radiofrequency energy to heat, collapse, and seal off larger veins. As it is a more invasive form of treatment, you will require day surgery at a hospital. The advantage of this is that the majority of surface and underlying veins can be dealt with at the one time.
In order to identify the problem vein, an ultrasound will be needed to map the course of the underlying vein. Once this has been done, a small incision will be made (around 2mm), where a thin tube is placed into the vein. A microfiber will be threated through this tube and placed around 2cm from the groin. From here, radiofrequency will be delivered to heat the vein, causing it to contract and collapse. This process is repeated in 7cm segments until the microfiber is withdrawn from the vein.
After the procedure, you will require a short recovery time. This will include around 30 minutes light of exercise twice a day for one week. Compression stockings will need to be worn for continually day and night for three days, and then just during the day for three weeks.
