Radio Frequency Ablation (VNUS closure)

Family running in a fieldThe VNUS Closure procedure is a minimally invasive treatment which can be performed under local anaesthetic to treat truncal venous incompetence.  Patients can usually walk out of hospital within an hour of treatment and return to normal activities within a few days.  There is evidence to suggest that this technique causes less pain and bruising when compared to traditional vein stripping or laser therapy and most patients achieve a good cosmetic outcome with minimal or no scarring.  If both legs are to be treated then these are usually done at separate sittings under local anaesthetic or may be done simultaneously under general anaesthetic.  A special catheter is inserted into the varicose vein through a small incision in the skin.  The tiny catheter, powered by radio-frequency (RF) energy, delivers heat to the vein wall.  As the thermal energy is delivered, the vein wall shrinks and the vein is sealed closed.  Once the diseased vein is sealed shut, blood then naturally reroutes to healthy veins.  After treatment, you will usually be required to wear a full length compression stocking permanently for the first 5-7 days and then daytime only for a further 7-10 days.  This treatment may be performed alone or in some cases may be combined with some stab avulsions (local excisions) of any prominent visible varicose veins.
