“…In this study, for transfemoral access, the bent wire technique had a lower filter tilt ratio than did the original push or hydrophilic stiff wire techniques. The angle between the IVC and the iliac vein affects filter tilting at deployment [23][24][25]. The bentwire technique reduces the angle and allows the filter tip to be positioned in the center of the IVC lumen, as illustrated in Fig.…”

To compare filter tilt and filter jumping during Option inferior vena cava (IVC) filter deployment with 3 different wires techniques using a 3-dimensional (3D) printing vena cava phantom. Materials and methods: An IVC 3D printed vena cava phantom was made from a healthy young male's computed tomographic data. Option IVC filters were deployed with 3 different wires: i) original push wire, ii) hydrophilic stiff wire, and iii) bent stiff wire. Right internal jugular and right femoral access were used 5 times with each wire. Filter tilt angle, tilt ratio, jumping, and tip abutment to the IVC wall were analyzed. Results: The transfemoral approach with original push wire had significantly higher tilt angle than did the transjugular approach (6.1˚± 1.9 vs. 3.5˚± 1.3, p = 0.04). Mean tilt ratio was significantly lower with the bent wire with transfemoral access (0.49 ± 0.13 vs. 0.78 ± 0.18 [original push-wire] and 0.67 ± 0.08 [stiff wire], p = 0.019). The ratio was lower also with original push wire with transjugular access (0.34 ± 0.19 vs. 0.57 ± 0.11 [stiff wire] and 0.58 ± 0.17 [bent wire], p = 0.045). Filter jumping occurred more often with the transjugular approach with original push wire than with stiff or bent-wire delivery. Filter tip abutment to the IVC wall occurred only with the transfemoral approach. Conclusions: Bent wire with transfemoral access and original push wire with transjugular access had lower filter tilt ratio at Option IVC filter deployment. However, filter jumping was common using the original push wire with transjugular access.
