The iliac vein pressure and pressure recovery time (time taken for pressure to return to resting levels) were measured in four states: rest, affected limb elevation, ankle extension and flexion, and gastrocnemius muscle compression. Bilateral comparisons and pre- and post-treatment assessments were conducted.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n The left iliac vein pressure in the four states (42.40 \u00b1 16.08 mmH\n 2<\/jats:sub>\n O, 51.23 \u00b1 17.63 mmH\n 2<\/jats:sub>\n O, 70.26 \u00b1 25.55 mmH\n 2<\/jats:sub>\n O, and 111.47 \u00b1 58.78 mmH\n 2<\/jats:sub>\n O) and pressure recovery time (25.57 \u00b1 10.65 s) were significantly higher compared to the right iliac vein pressure (30.67 \u00b1 7.46 mmH\n 2<\/jats:sub>\n O, 36.55 \u00b1 8.59 mmH\n 2<\/jats:sub>\n O, 44.84 \u00b1 11.17 mmH\n 2<\/jats:sub>\n O, and 52.96 \u00b1 14.06 mmH\n 2<\/jats:sub>\n O) and recovery time (18.92 \u00b1 21.07 s) (\n p<\/jats:italic>\n = .000). The pressure in patients with left iliac occlusion (179.07 \u00b1 31.64 mmH\n 2<\/jats:sub>\n O) was significantly higher than in patients with stenosis (79.91 \u00b1 33.54 mmH\n 2<\/jats:sub>\n O) (\n p<\/jats:italic>\n = .000). In eight patients who underwent intraluminal iliac venous therapy, postoperative pressure (37.29 \u00b1 7.53 mmH\n 2<\/jats:sub>\n O, 44.74 \u00b1 5.10 mmH\n 2<\/jats:sub>\n O, 53.76 \u00b1 5.36 mmH\n 2<\/jats:sub>\n O, and 61.96 \u00b1 7.27 mmH\n 2<\/jats:sub>\n O) and pressure recovery time (20.88 \u00b1 5.67 s) significantly improved compared to preoperative measurements (50.53 \u00b1 8.21 mmH\n 2<\/jats:sub>\n O, 60.03 \u00b1 7.50 mmH\n 2<\/jats:sub>\n O, 96.88 \u00b1 11.67 mmH\n 2<\/jats:sub>\n O, 177.11 \u00b1 22.40 mmH\n 2<\/jats:sub>\n O, and 35.50 \u00b1 6.95 s) (\n p<\/jats:italic>\n < .01). Despite improvements, postoperative left iliac pressure remained significantly higher than the right iliac pressure in different states (\n p<\/jats:italic>\n < .05). The left iliac vein pressure increased significantly during ankle extension and flexion, as well as gastrocnemius muscle compression compared to resting and elevated limb states (\n p<\/jats:italic>\n < .05).\n <\/jats:p>\n <\/jats:sec>\n \n Conclusion<\/jats:title>\n The innovative high-precision iliac vein pressure measuring device enables rapid and accurate quantification of iliac vein pressure. As a functional diagnostic method, it holds considerable clinical value in diagnosing iliac vein compression syndrome and evaluating treatment efficacy.<\/jats:p>\n <\/jats:sec>","DOI":"10.1177\/17085381251325652","type":"journal-article","created":{"date-parts":[[2025,3,17]],"date-time":"2025-03-17T06:13:56Z","timestamp":1742192036000},"page":"130-141","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["An experimental study of a novel high-precision iliac vein pressure measuring device to evaluate iliac vein compression syndrome"],"prefix":"10.1177","volume":"34","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6064-8701","authenticated-orcid":false,"given":"Liguo","family":"Liu","sequence":"first","affiliation":[{"name":"Department of Vascular Surgery, Tianjin Hospital"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiangchen","family":"Dai","sequence":"additional","affiliation":[{"name":"Department of Vascular Surgery, Tianjin Medical University General Hospital"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiujun","family":"Zhang","sequence":"additional","affiliation":[{"name":"Department of Vascular Surgery, Tianjin Hospital"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Junjie","family":"Huang","sequence":"additional","affiliation":[{"name":"Department of Vascular Surgery, Tianjin Hospital"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ziyuan","family":"Zhao","sequence":"additional","affiliation":[{"name":"Department of Vascular Surgery, Tianjin Hospital"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Cunfa","family":"Liu","sequence":"additional","affiliation":[{"name":"Department of Vascular Surgery, Tianjin Hospital"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2025,3,17]]},"reference":[{"key":"e_1_3_6_2_2","doi-asserted-by":"publisher","DOI":"10.2147\/VHRM.S203349"},{"key":"e_1_3_6_3_2","doi-asserted-by":"publisher","DOI":"10.1002\/bjs.1800540605"},{"key":"e_1_3_6_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jvsv.2018.08.009"},{"key":"e_1_3_6_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ejvs.2018.04.013"},{"key":"e_1_3_6_6_2","doi-asserted-by":"publisher","DOI":"10.1177\/0268355514529206"},{"key":"e_1_3_6_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jvsv.2017.11.015"},{"issue":"1","key":"e_1_3_6_8_2","first-page":"117","article-title":"Randomized doubleblinded study comparing clinical versus endovascular treatment of iliac vein obstruction: preliminary results","volume":"3","author":"Rossi FH","year":"2015","unstructured":"Rossi FH, Kambara AM, Izukawa NM, et al.
