Sclerotherapy is used to close abnormal surface veins. In sclerotherapy, medicine is injected into the abnormal vein to make it scar shut.
For larger veins, an ultrasound machine is often used to guide the medicine into the vein. Also for larger veins, medicine is often combined with air, a process called foaming, to make it more effective.
