Improved foam for varicose veins found to be safe in preliminary results from phase II trial

A small group of patients with a common heart defect who were treated for varicose veins with an injectable microfoam experienced no neurological, visual or cardiac changes as a result of the treatment, according to preliminary results from a phase II trial. The results are being presented today (March 17) in Washington, D.C., at the annual scientific meeting of the Society of Interventional Radiology (SIR).
