Abstract
In a method for sclerotherapy for treating varicose veins, a flushing solution, such as sterile saline solution, is initially injected into the vein or vessel being treated. The flushing solution displaces or flushes out blood from the treatment site of the vessel. A sclerosing agent is then injected into the treatment site. The displacement of blood before introduction of the sclerosing agent reduces complications. A syringe assembly useful for performing the method has first and second reservoirs sealed off from each by an end cap. The end cap is removed just before use. A needle is attached and is connected to both reservoirs. Flushing solution is delivered from the first reservoir followed by sclerosing solution delivered from the second reservoir, without removing the needle from the vessel.
