SALVS Position Statement on the Use of Cyanoacrylate Glue (CAG) Occlusion for Varicose Veins
Varicose veins are abnormally enlarged (more than 3mm while standing), tortuous, superficial veins. They occur most commonly in the lower legs but can occur anywhere. They are part of a spectrum of chronic venous disorders of the lower leg.
Varicose veins are very common and can occur in up to 30% of the population. The exact cause of varicose veins is unknown. A number of factors including abnormalities of the vein wall, inflammation and increased pressure in the vein play a role. Increased pressure is mostly due to malfunction of the valves and reflux, inadequate calf muscle pump function and occasionally due to proximal obstruction due to thrombosis or compression by a tumour or major artery.
