Ultrasound Guided Injections:

veins

This is the part of commonly known term "sclerotherapy".  The whole concept behind this method is to deliver into the vein a chemical that acts as an irritant to the normal vein lining causing it to collapse and close with time. There are many irritants (sclerosants) currently on the market used daily all over the world.  As a hostile to our organism liquid, it may cause allergies and a local tissue inflammatory reaction. However, it is indeed designed to cause an inflammatory reaction in the vein.  We use Sotradecol (STS, Thromboject) solution since till recently it was the only FDA approved sclerosant.   With ultrasound guided injections usually the bigger vessels such as main veins and their branches are the targets. Perforating veins which often cause ulcers in later stage of disease can also be treated with this method. Stronger concentration of the irritant is being used in forms of either liquid or foam. Whereas liquid can be flashed quickly by the flow in the vein, the foam, if created correctly, will stay in the vessel for 10-15 minutes or even longer allowing the chemical to stick to the wall and destroy endothelium. To avoid air travelling to our vital organs we use CO2 and Sotradecol to create the foam in 1:4 proportions. Use of ultrasound is necessary during this procedure to ensure the precise delivery of the foam to the target and to avoid any spill of the sclerosant into the deep vein system. Ultrasound guided injections are not covered by MSP or third party insurance
