The Use of Paired Optionally Retrievable Günther Tulip Filters in Trauma Patients with Anatomical Variants

ABSTRACT

Inferior vena cava (IVC) filtration is commonly performed to protect against pulmonary embolism in acutely injured patients with contraindications for anticoagulation therapy. Increasingly, optionally retrievable IVC filters are utilized, particularly in younger patients with longer life expectancies. There are well-described anatomical variants that preclude the typical infrarenal deployment of IVC filters. We describe three cases in which trauma patients with congenital anomalies required temporary prophylaxis with IVC filters. One patient had a duplication of the IVC requiring filter deployment in each IVC limb. The second patient had a low inserting accessory left renal vein, and a third patient had a megacava. Both of these patients required filter deployment in each common iliac vein. In each case, a pair of optionally retrievable Günther Tulip filters was deployed and subsequently retrieved.
