Radiofrequency Ablation for Varicose veins (RFA)
Radiofrequency ablation is a minimally invasive treatment to remove varicose veins. This technique uses radiofrequency energy (instead of laser energy) to heat up and damage the wall inside a vein, close it and destroy it. A fine tube (catheter) is passed through the skin near the knee and then threaded up the diseased long saphenous vein. The catheter is attached to a power unit that heats up the end of the catheter. The heat seals the walls of the vein, so that no blood can flow through it. The operation can be done under general or local anaesthetic.
How is RFA different to surgical treatment?
Surgical treatment usually requires a cut in the groin to tie off the vein, after which it is removed by a stripping device. This can cause significant bruising. RFA avoids the need for a cut in the groin and there is minimal bruising, so people who have RFA can usually return to daily routines sooner, than those who have standard treatment.
