<unk>  is a procedure used to treat blood vessels or blood vessel malformations (vascular malformations) and also those of the lymphatic system. A medicine is injected into the vessels, which makes them shrink. It is used for children and young adults with vascular or lymphatic malformations. In adults,<unk>  is often used to treat varicose veins and hemorrhoids. <unk>  is one method, along with surgery, radiofrequency and laser ablation, for treatment of varicose veins and venous malformations. In ultrasound-guided<unk>  , ultrasound is used to visualize the underlying vein so the physician can deliver and monitor the injection.<unk>  should be done under ultrasound guidance after venous abnormailities have been diagnosed with duplex ultrasound.<unk>  under ultrasound guidance and using microfoam sclerosants has been shown to be effective in controlling reflux from the sapheno-femoral  and sapheno-popliteal junctions. However, some authors believe that<unk>  is not suitable for veins with reflux from the greater or lesser saphenous junction, or veins with axial reflux (above the knees).
