Abstract
PURPOSE
To evaluate safety and retrieval success of retrievable suprarenal inferior vena cava (IVC) filters.
MATERIALS AND METHODS
A retrospective chart review of patients who received a retrievable suprarenal IVC filter between January 2008 and December 2017 was conducted. Suprarenal IVC filters were placed in 24 female and 27 male patients. The most common indications for filter placement were IVC thrombus (n = 20; 39.2%) and iliofemoral venous thrombosis with contraindication to anticoagulation (n = 16; 31.3%). The most common indications for suprarenal placement were IVC thrombus (n = 20; 39.2%), anatomic variants (n = 17; 33.3%), and external IVC compression (n = 8; 15.8%). Duplicated IVC was the most common anatomic variant requiring suprarenal placement (n = 7; 13.7%).
RESULTS
Günther Tulip (n = 40; 78.4%), Denali (n = 10; 19.6%), and Celect (n = 1; 2.0%) filters were used. Retrieval was attempted in 27 of the 51 filters placed (52.9%). Of the 27 attempted retrievals, the technical success rate was 100% (27/27). The median dwell time was 87.0 days (95% confidence interval, 28-137 d). One complication involving fractured struts during filter retrieval occurred. No significant change in craniocaudal filter position, lateral filter tilt, or renal function between placement and retrieval was observed (P < .05). There were no instances of indwelling filter fracture.
CONCLUSIONS
Suprarenal IVC filters, when indicated, can be placed and retrieved with a low complication rate.
