Retrieval of Inferior Vena Cava Filters Temporarily Placed in a Suprarenal Position: A Review of 13 Patients.

Abstract

To evaluate the safety and efficacy of retrieval of inferior vena cava filters (IVCF) temporarily placed in a suprarenal position. Retrieval of IVCF placed in a suprarenal position was performed in 13 patients (5 men and 8 women; mean age: 45.1 ± 13.8 years) between July 2006 and May 2018 using either a loop snare technique or endobronchial forceps. Electronic medical records were reviewed for patient demographics and procedural information. Inferior vena cava filters retrieved included Option Elite (n = 9, 69%) and Günther Tulip (n = 4, 31%). Caval thrombosis was not detected in any patients on pre- or postretrieval cavogram. Eleven suprarenal IVCF (84%) were retrieved during the first retrieval attempt after a median indwelling time of 1.8 months (range, 0.03-12.10 months). Retrieval was initially unsuccessful in 2 (16%) patients with Option Elite filters, but both were successfully removed on second attempt using endobronchial forceps. Thirteen suprarenal IVCF (100%) were ultimately retrieved. Endovascular retrieval of IVCF temporarily placed in a suprarenal position is safe and efficacious.
