The use of the Wallstent endovascular prosthesis in the treatment of malignant inferior vena cava obstruction.

We report three cases of inferior vena cava (IVC) obstruction due to metastatic liver disease treated with a self-expanding Wallstent endoprosthesis (Schneider SA, Zurich, Switzerland). All three patients experienced symptomatic relief during their remaining few weeks of life. The Wallstent is effective and easy to deploy, and should be considered for use in the management of such patients. The literature to date on IVC stenting is also reviewed.
