“…The refinement introduced in these designs, devised to enhance the filter ability to capture small blood clots and to strengthen the attachment to the vein wall, comes at a price in terms of increased values of both F f (a direct consequence of the increased surface area) and F p . The notion that the presence of high F d values may contribute to long‐term mechanical fatigue is qualitatively consistent with the relatively high rate of strut fractures reported for the real counterpart of filters 2 and 4() and the very high (92 % ) occurrence rate of IVC perforation (without clinical sequelae) reported for the real filter 2 …”

Computational fluid dynamics was used to simulate the flow of blood within an inferior vena cava (IVC) geometry model that was reconstructed from computed tomography images obtained from a real patient. The main novelty of the present work is that we simulated the implantation of 4 different filter models in this realistic IVC geometry. We considered different blood flow rates in the range between V =20 and V =80 cm /s, and all simulations were performed with both the Newtonian and a non-Newtonian model for the blood viscosity. We compared the hemodynamics performance of the different filter models, and we paid a special attention to the total drag force, F , exerted by the blood flow on the filter surface. This force is the sum of 2 contributions: the viscous skin friction force, which was found to be roughly proportional to the filter surface area, and the pressure force, which depended on the particular filter geometry design. The F force is relevant because it must be balanced by the total force exerted by the filter hooks/struts on the IVC wall at the attachment locations. For the highest V value investigated, the variation in F among filters was from 116 to 308 dyne. We also showed how the present results can be extrapolated to obtain good estimates of the drag forces if the blood viscosity levels change, ie, if the patient with a filter implanted is treated with anticoagulant therapy.

“…14 Multiple studies have shown that the associated complication rates of retrievable filters are higher than those of permanent filters; such an association is concerning given that retrievable filter usage exceeds permanent filter usage. 14,15 The increase in retrievable filter usage is likely attributable to their attractive risk-benefit calculation. In theory, retrievable IVC filters should be perfect for patients who have conditions that increase VTE risk but create temporary contraindications, such as trauma or major surgery, to anticoagulation.…”

The "Things We Do for No Reason" (TWDFNR) series reviews practices that have become common parts of hospital care but may provide little value to our patients. Practices reviewed in the TWDFNR series do not represent "black and white" conclusions or clinical practice standards but are meant as a starting place for research and active discussions among hospitalists and patients. We invite you to be part of that discussion.

Purpose To determine practice patterns of inferior vena cava filters (IVCFs), retrieval rates, and reasons why retrievable-IVCFs (R-IVCFs) are kept permanent. Methods A total of 399 patients who received IVCFs at Third Hospital of Hebei Medical University from January 2017 to December 2017 were registered and retrospectively studied. Date of demographics, baseline medical history, dwell time, reasons why R-IVCFs were kept permanent, and R-IVCFs thrombus were collected. Results A total of 399 IVCFs were placed during the study period including 27 permanent IVCFs and 372 R-IVCFs. Among all patients who received R-IVCFs, the mean dwell time was 18.25 ± 16.60 days, follow-up rate was 96.24% (358/372), and 337 R-IVCFs were attempted to be removed. Except one, 336 R-IVCFs were retrieved successfully (336/372, 90.32%). Sixty-four R-IVCFs thrombi were found during retrieval including 53 small-size thrombi (< 1 cm × 1 cm) and 13 large-size thrombi (>1 cm × 1 cm). Fifty-three R-IVCFs with small-size thrombi were removed successfully with no additional treatments. Twelve large-size thrombi were retrieved successfully after catheter-directed thrombolysis. Conclusions With good follow-up, the retrieval rate could be improved to 90.32%. The main reasons why R-IVCFs were kept permanent were to avoid losing follow-up and overcome inappropriate selections of indications or IVCF types. And R-IVCFs with thrombus could be removed safely.
