Information for the public
There is not much good evidence about how well cyanoacrylate glue occlusion for varicose veins works or how safe it is. The procedure should only be used if extra care is taken to explain the risks, and extra steps are put in place to record and review what happens. It should only be done by health professionals who can offer a range of treatments for varicose veins, and who have had special training in the procedure.
Your health professional should fully explain what is involved in having this procedure, and discuss the possible benefits and risks with you. In particular, they should explain the uncertainty about the evidence on how likely it is to improve your symptoms and possible side effects. You should also be told how to find more information about the procedure. You should only be asked if you want this procedure after having this discussion. Your health professional should ask you if details of your procedure can be collected.
NICE said that cyanoacrylate glue occlusion may be possible without the need for large doses of local anaesthetic, or compression bandaging. NICE also said that, because there is relatively little published evidence about the procedure, there may be rare or uncommon risks that have not been seen yet.
