Endovenous laser procedure in a clinic room: feasibility and side effects study of 1,700 cases.

Objectives: To assess the feasibility of saphenous veins ablation by laser in a clinic room. To study immediate and short term (1 to 6 months) complications and to pinpoint those that could be directly linked to this environment. Efficacy of the technique should also be documented.

Methods: Retrospective study (22 centres) carried out in France and Switzerland. Patients with insufficiency of great saphenous vein (GSV) or small saphenous vein (SSV). Clinical stages of clinical, [corrected] aetiological, anatomical and pathophysiological classification (CEAP) C2 to C6. Endovenous laser procedures were performed outside an operating theatre, under local anaesthesia and without high ligation. Efficacy criteria: occlusion of the vein and disappearance of the pathological reflux (duplex scan assessment). The side effects and complications were studied.

Results: A total of 1703 procedures (1422 patients) were performed; 74% of the patients were women. [corrected] The mean age of the patients was 57. A total of 1394 GSV and 309 SSV were treated (mean diameters 7.2 mm and 6.4 mm, respectively). Overall success level was 97% and mean length of veins treated was 40 cm for GSV and 21 cm for SSV. Energy applied in joules per centimeter was homogenous (mean and median 64 for GSV and 65 for SSV). Complications were rare and 'simple' apart from one pulmonary embolism which occurred 10 days after a GSV procedure, although no deep vein thrombus was found. A total of two infections were observed: one was an infection localized at the site of access and the other was erysipelas. [corrected]

Conclusion: Except 2 limited infections (0.1%), this large retrospective study of laser procedures performed outside the operating theatre did not reveal any significant specific complications as regards the environment required. The efficacy results were equivalent to those found in the literature. Regarding cost and constraints induced by operating theatre environment, the clinic room should be able to offer an easier and economic alternative option for saphenous veins ablation with laser [corrected]
