INDICATIONS
Varicose veins may occur in the presence or absence of either symptoms or an underlying functional venous disorder, such as reflux.30 Candidates for sclerotherapy manifest persistent symptoms (such as pain, aching, and swelling) and signs (such as telangiectasias, reticular veins, varicose veins, pigmentary changes, and ulceration) of venous disease after 6 months of medical therapy.
Sclerotherapy techniques to achieve perforator and saphenous closure are available for patients with documented reflux (i.e., retrograde flow >0.5 second duration) as a source of their symptoms. For patients with ulceration refractory to medical management, or those who manifest recurrent ulceration, UGS of perforators can lead to significant reduction of symptoms and signs. For small varicosities that are mostly a cosmetic concern, sclerotherapy can be performed following physical examination without additional diagnostic studies, as these patients are not as likely as symptomatic patients to have underlying venous reflux.30,31 Patients with complaints of recurrent bleeding and stigmata of recent venous hemorrhage may benefit from sclerotherapy of that vein site.32,33 Sclerotherapy is often successful even in the presence of venous insufficiency.32
