Technique for transjugular placement of an umbrella filter in a left inferior vena cava

Abstract

Transjugular placement of a Mobin-Uddin umbrella fillter in an anomalous left inferior vena cava to prevent recurrent pulmonary embolization may present technical difficulties. Preforming a slight curve in the applicator wire a short distance from its tip allowed catheterization and proper position of a fillter in two cases.
