An accompanying morphological alteration turned IVC into a quasi-round shape with Lin CCC of 0.870, and orientation was significantly altered after filter placement. In patients with type 1, 3, and 4 IVCs, the mean diameter of the IVC increased almost 1.5-fold in the minor axis (95% confidence intervals [CIs]=\u22127.77 to \u22125.83,\n                      <jats:italic toggle=\"yes\">p<\/jats:italic>\n                      &lt;0.001), while only a slight expansion of the major axis to its initial size (\n                      <jats:italic toggle=\"yes\">p<\/jats:italic>\n                      &gt;0.05). Greater IVC enlargement rate was seen in the diameter of the minor axis than in the major axis (95% CI=40.31 to 65.12,\n                      <jats:italic toggle=\"yes\">p<\/jats:italic>\n                      &lt;0.001). Notably, regional clots around the filter were found in 22 (31.4%) patients. Among them, 14 (20.0%) were located on the anterior or posterior walls of caval minor axis, 5 (7.1%) in the lateral walls, and 3 (4.3%) in the central part of the IVC filter. Patients exhibited a higher incidence of clots on anterior and posterior walls compared to lateral wall (20.0% vs 7.1%,\n                      <jats:italic toggle=\"yes\">p<\/jats:italic>\n                      =0.014).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>The morphology of IVC shifted toward an approximated as circles after filter placement, with greater diameter changes seen in the minor axis compared to the major axis, where filter-related thrombosis most occurs.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Clinical Impact<\/jats:title>\n                    <jats:p>The findings of this study offer insights into the biomechanical interaction between the inferior vena cava (IVC) and spindle-shaped filters, highlighting the anisotropic dimensional changes triggered by filter placement. The pronounced expansion along the minor axis, where filter-related thrombosis was more frequently observed, underscores a previously underrecognized risk factor for post-implantation complications. These results indicate that perioperative optimization of IVC dimensions and vigilant post-placement monitoring are crucial for improving patient outcomes.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/15266028251319137","type":"journal-article","created":{"date-parts":[[2025,2,21]],"date-time":"2025-02-21T07:43:37Z","timestamp":1740123817000},"page":"1904-1913","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":3,"title":["Radiographic Characterization of Inferior Vena Cava and Its Reaction Following Filter Placement: A Single-Center Retrospective Study"],"prefix":"10.1177","volume":"33","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4580-3232","authenticated-orcid":false,"given":"Maofeng","family":"Gong","sequence":"first","affiliation":[{"name":"Department of Vascular and Interventional Radiology, Nanjing First Hospital, Nanjing Medical University, Nanjing, P.R.
