Our service specialises in treating varicose veins and venous ulcers. We perform many of our surgical procedures under local anaesthetic, using keyhole techniques.

Our aim is to improve the care of patients with symptomatic varicose veins and we are constantly trialling new techniques. We perform new, less painful surgical procedures such as cyanoacrylate (or ‘glue’) ablation, where an adhesive is used instead of heat to treat varicose veins. We are also trialling new devices like the Clarivein (which is used for mechanochemical endovenous ablation) and carrying out research into the effectiveness of compression stockings following venous surgery.

Your inpatient stay Your stay in hospital

You may need to stay at one of our hospitals to have a procedure or receive treatment, either overnight as an inpatient or during the day as a day patient. Ahead of your inpatient stay, you will usually need to attend a pre-operative assessment appointment.
