Surgery remains the traditional technique for treating varicose veins and requires a general anaesthetic. |
 |
EVLT involves the introduction of a thin tube (catheter) into the main superficial vein on the inside of the thigh through a small skin incision over the inside of the knee. |
 |
Sclerotherapy involves the use of a sclerosant and has been used for many years to treat small varicose veins.

This is an alternative minimally-invasive technique using a similar principle to laser treatment. |
 |
This involves injecting a small amount of a sclerosant into the inside of the thread veins using a very fine needle. Alternatively a very fine needle is introduced over the vein which transmits a local heating effect making the vein disappear instantly in most cases.

This is an alternative minimally-invasive technique using a similar principle to laser treatment. General anaesthesia is more commonly used and a catheter is introduced into the main superficial thigh vein under ultrasound guidance. The tip of the catheter is positioned at the junction of the superficial and deep vein in the groin and a probe generating radiofrequency energy is used to heat up the inside of the vein causing it to collapse down.
Smaller calf veins lower down in the leg can be treated during the same general anaesthetic with multiple avulsions through 1mm incisions.
