Ultrasound-guided foam sclerotherapy is used to treat both deeper and superficial varicose veins. A sclerosing agent is agitated to make Microfoam bubbles usually with CO2 and is injected in superficial varicose veins. This results in vein occlusion and resolution of varicose veins without the need for incisions. The larger supplying veins are often treated with laser or radiofrequency ablation and sclerotherapy is then performed in any residual varicosities to complete the treatment cycle.
Diagnostic vascular ultrasound is the best technique for screening both arterial and venous vascular problems in the lower extremities. Sonography can evaluate the lower extremity vasculature for arterial blockages, venous insufficiency, deep venous thrombosis and many other disorders. It gives excellent information regarding the patient’s underlying condition. Sonography is used to guide many vein treatments including greater saphenous vein ablation, foam sclerotherapy as well as the Venaseal therapy.
