Abstract:
A Vena Tech-LGM 30D/U filter (B. Braun/Vena Tech; Evanston, IL) opened incompletely after transjugular placement in the infrarenal vena cava. The cephalic points of the stabilizing side rails were open and had engaged the caval wall. The base of the filter failed to open. The filter would not successfully inhibit the clots and could possibly migrate. The filter base was not placed in a clot as shown with intraoperative venography before and after the placement. The balloon of a 6F Fogarty catheter was used successfully to dilate the distal legs of the filter, and fully expand the base.
