Information for the public
The aim of endovenous mechanochemical ablation is to close the varicose vein. The procedure is done using local anaesthetic. Ultrasound imaging is used to identify the vein needing treatment. A tube with a rotating hollow wire at its tip is inserted through the skin into the affected vein in the leg. As the tube is pulled back out of the vein, the wire is rotated, damaging the lining of the vein. At the same time, a chemical is injected through the hollow wire into the vein, causing it to shrivel and close. Patients are advised to wear compression stockings for about 2 weeks after the procedure.
