Vol 19. No. 4. 2012 161 EDITORIAL Dear Readers, This issue of Phlebolymphology offers an exciting insight into some actual and very relevant fields of phlebology. Renate van den Bos and Marianne de Maeseneer, both working at the Dermatological University clinic in Rotterdam and outstanding experts in the field, discuss the strengths and weaknesses of the endovenous thermal ablation of varicose veins. They point out that Hugo Partsch duplex-guided endovenous procedures have widely replaced classical Editor in Chief stripping and that the newly developed steam ablation procedure has a promising future, being safer, faster, easier, and cheaper than endovenous laser and radiofrequency ablation (see also the article by René Milleret: Obliteration of Varicose Veins with Superheated Steam. Phlebolymphology. 2011;19:174-187). In an extensive review article, Professor Byung-Boong Lee, George Washington University School of Medicine, shows that knowledge of embryology may be key to understanding vascular pathologies, for instance for the differentiation between truncular and extratruncular forms of vascular malformations. His article contains beautiful illustrations of clinical conditions: radiological, MRI, and nuclear medicine pictures and schematic drawings, which are helpful to understand this very complex topic. Jean-Jérôme Guex from Nice, together with a group of prominent coauthors working on the Vein Consult Program, a worldwide epidemiological survey (see the article by Francoise Pitsch in the last issue of Phlebolymphology; 2012;19:132-137), has analyzed a large group of symptomatic C0 patients, a cohort of patients that is well-known to every phlebologist. Out of a total of 91 545 subjects, 19.7% did not show any visible or palpable signs of venous disease—this is the definition of the C0 class according to the CEAP classification—but presented with subjective symptoms. Most of the 14% of patients who underwent a duplex scan examination had superficial reflux, and 18% had deep reflux. The authors suggest that an “inflammatory hypothesis” may be the cause of the symptoms, which include a reduced quality of life, and propose that venoactive drugs should be used for treatment. Based on their extraordinary experience with sclerotherapy using Sigg’s technique, Francesco and Giovanni Ferrara from Naples have showed, in a case series of 60 patients, that diabetes mellitus with good glycemic control (HbA1c<6.5%) is not a contraindication for this technique, but rather gives equally good results and no more complications than in nondiabetics.

No. 4. 2012 PHLEBOLOGY Endovenous thermal ablation for varicose veins: strengths and weaknesses Renate R. van den BOS, ABSTRACT Marianne M.G. de MAESENEER Endovenous ablation is a frequently used method for treating varicose veins. Department of Dermatology, Endovenous laser ablation is the most frequently used technique, followed by Erasmus MC Rotterdam, The Netherlands radiofrequency ablation. Endovenous thermal treatments heat the vein, leading to thrombotic occlusion and finally fibrosis of the vein wall. Endovenous steam ablation is a new technique that has not yet been extensively studied. In this article, the procedures, strengths, and weaknesses of the currently available endovenous thermal ablation treatments are discussed. INTRODUCTION Endovenous treatment is currently one of the most frequently used methods for treating varicose veins. Varicose veins are manifestations of chronic venous disease (CVD), which may lead to serious complications. CVD is a common medical condition. The prevalence of varicose veins is estimated to range from 2%-40%.1-4 The prevalence of venous leg ulcers, the end-stage of CVD, is much lower. It is very difficult, if not impossible, to predict which patients with varicose veins will develop a leg ulcer. Nevertheless, it has been estimated that about half of venous leg ulcers are the result of superficial venous insufficiency.5 The cost of treating leg ulcers is very high; the treatment of varicose veins, which may reduce the incidence of leg ulcers by 50%, is therefore likely to be cost-effective. Treatment for varicose veins can roughly be divided into four categories: compression therapy, surgical treatment, sclerotherapy, and endovenous thermal ablation. Surgical ligation of the junction with or without stripping has been the standard of care in the treatment of insufficient great and small saphenous veins for more than 100 years. In the last decade, endovenous thermal ablation (EVTA) procedures have become the most frequently used therapy for saphenous varicose veins, Keywords: endovenous ablation treatments, saphenous especially in countries where reimbursement of the procedure has been insufficiency, thermal ablation, varicose veins introduced. Such minimally invasive techniques meet the demand for cosmetically superior, less invasive and more successful treatment modalities. Only introduced 10 years ago, these techniques have radically changed the Phlebolymphology. 2012;19(4):163-169. Phlebolymphology. Vol 19.

The advantage of EVTA is that it is junction
