There is not enough evidence about how well this procedure works. This type of procedure can cause complications. So, it can only be done with special arrangements. This means you will have regular appointments afterwards to check how well it is working or if it has caused problems.
Chronic limb threatening ischaemia happens when blocked arteries reduce the blood flow in the lower leg. Symptoms include pain and ulcers. In severe cases the leg tissue dies because of the lack of blood supply and there is a high risk of losing the limb. In this procedure, an artery in the lower leg is joined to a large vein to divert blood flow through the vein towards the foot, bypassing the blocked arteries. The valves inside the vein are removed (superficial venous arterialisation) and smaller veins are blocked off. The aim is to improve symptoms and preserve the affected limb by restoring blood flow.
You can search the NHS website for information about consultants and hospitals that offer this procedure.
