Review of Published Information on Foam Sclerotherapy
New data on foam sclerotherapy of varicose veins has been recently published. OBJECTIVE
To identify the current treatment modalities and their effectiveness in use of foam sclerotherapy. MATERIALS AND METHODS
Review of the recent literature regarding clinical treatment of varicose veins using foam sclerotherapy, with emphasis on safety and efficacy. RESULTS
Foam sclerotherapy of the great saphenous vein is more effective than liquid. Higher sclerosant concentrations tend to induce higher occlusion. Catheter-assisted sclerotherapy may further improve occlusion rates. To achieve adequate occlusion, vein diameter and volume of foam must be matched. If a critical foam volume is exceeded, the risk of deep venous thrombosis increases. Foam sclerotherapy offers the possibility of using lower sclerosant concentrations than with liquids. Foam sclerotherapy can also be used in venous malformations and periulcerous tributaries. Side effects are hyperpigmentation, skin necrosis, scotoma, and thromboembolic events. Thromboembolism prophylaxis is necessary only in patients with special risk factors. CONCLUSION
Foam sclerotherapy has significantly better efficacy than liquid. It is essential to select the correct concentration and the correct foam volume. In the hands of an experienced physician, foam sclerotherapy is a safe and effective option for treating varicose veins.
