Superficial venous arterialisation and selective venous occlusion for chronic limb threatening ischaemia in people with no other option for revascularisation
Closed for comments This consultation ended on at Request commenting lead permission
Description
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 (selective venous occlusion). The aim is to improve symptoms and preserve the affected limb by restoring blood flow.
