What is VNUS Closure?
VNUS closure is a technique whereby the superficial varicose veins can be destroyed using an electric current. Under ultrasound control a fine catheter is inserted into the vein that runs up the inside of the thigh, and when the catheter is in the correct position a current is applied which heats up the vein and destroys it.
Are there any problems with this technique?
Sometimes it is difficult to control all the superficial veins and it is necessary to remove some through multiple ministab avulsions either at the same time or as a separate surgical procedure. In very thin patients there may be some scarring or discolouration associated with removing the long saphenous vein.
