Advances in the treatment of superficial venous insufficiency of the lower extremities.
Minimally invasive techniques for ablation of incompetent saphenous veins using either radiofrequency or laser energy sources have gained acceptance and are being widely applied today. Tumescent local anesthesia provides protection to tissues surrounding the treated veins and allows the procedures to be done on conscious patients. Results thus far compare favorably with surgical stripping procedures. Efficacy rates and complication rates support these techniques, and patient satisfaction appears high. Microphlebectomy, also minimally invasive, has advantages over direct incisional excision of varicosities. Foam sclerosant injection therapy has been used extensively in Europe and is proving useful in treating refluxing pelvic veins and recurrent varicosities.
