For the 48th meeting of the International Society for Cardiovascular Surgery, North American Chapter in June 2000, we were asked to organize a presentation with the title displayed above. We welcomed this opportunity because the phrase 'growing the practice' literally means giving greater service to underserved patients with vascular disorders. Underserved individuals with vascular disorders include those with nonatherosclerotic arterial disorders, patients with lymphedema, and individuals with a variety of venous disorders including venous insufficiency. The majority of these conditions are not surgical, but venous insufficiency commands attention because its treatments are interventional. Therefore, this presentation will discuss prevalence of venous insufficiency, a unifying concept of its pathophysiology, how treatment may be selected, what the new technology provides, and then a description of coding issues and whether or not interventions are actually worthwhile from the point of view of the patient.
