Options available for surgical treatment of varicose veins are as follows:■Ankle-to-groin saphenous vein stripping (with stab avulsion) ■ Segmental saphenous vein stripping (with stab avulsion) ■ Saphenous vein ligation: high, low, or both ■ Saphenous vein ligation and sclerotherapy ■ Saphenous vein ligation (with stab avulsion) ■ Stab avulsion of varices without saphenous vein stripping (phlebectomy) ■ Endoluminal occlusion of the saphenous vein by radiofrequency (RF) or laser energy
