A total of 726 patients were included (364 females, 362 males; mean patient age: 61.9 \u00b1 15.9 years). Board-certified radiologists reviewed all CT scans. Significant left iliac vein compression was defined as &gt;50% luminal narrowing.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Significant iliac vein compression was identified in 114 (15.7%) patients and was more common in females (19.5%) versus males (11.9%) (\n                      <jats:italic toggle=\"yes\">p<\/jats:italic>\n                      &lt; 0.01).

Compression was associated with lower BMI and more than twice the rate of ipsilateral DVT, despite no prior diagnosis of MTS. These findings suggest that incidental iliac vein compression could have more clinical significance than previously recognized.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/02683555261499780","type":"journal-article","created":{"date-parts":[[2026,10,16]],"date-time":"2026-10-16T14:10:52Z","timestamp":1792159852000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Sex differences and prevalence of prior deep vein thrombosis among patients with incidental iliac vein compression on computed tomography"],"prefix":"10.1177","author":[{"given":"Zohaib Y.","family":"Lakhani","sequence":"first","affiliation":[{"name":"Division of Vascular and Interventional Radiology"},{"name":"Mayo Clinic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christopher J.","family":"Reisenauer","sequence":"additional","affiliation":[{"name":"Division of Vascular and Interventional Radiology"},{"name":"Mayo Clinic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Forrest B.","family":"Linch","sequence":"additional","affiliation":[{"name":"Division of Vascular and Interventional Radiology"},{"name":"Mayo Clinic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Richard G.","family":"Frimpong","sequence":"additional","affiliation":[{"name":"Division of Vascular and Interventional Radiology"},{"name":"Mayo Clinic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Matthew R.","family":"Augustine","sequence":"additional","affiliation":[{"name":"Division of Vascular and Interventional Radiology"},{"name":"Mayo Clinic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8019-3337","authenticated-orcid":false,"given":"Edwin A.","family":"Takahashi","sequence":"additional","affiliation":[{"name":"Division of Vascular and Interventional Radiology"},{"name":"Mayo Clinic"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2026,10,16]]},"reference":[{"key":"e_1_3_5_2_2","doi-asserted-by":"publisher","DOI":"10.1161\/CIRCINTERVENTIONS.124.014160"},{"key":"e_1_3_5_3_2","doi-asserted-by":"publisher","DOI":"10.1177\/000313480006600710"},{"key":"e_1_3_5_4_2","doi-asserted-by":"publisher","DOI":"10.1161\/CIRCINTERVENTIONS.115.002772"},{"key":"e_1_3_5_5_2","doi-asserted-by":"publisher","DOI":"10.2214\/AJR.09.2793"},{"key":"e_1_3_5_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jvs.2003.12.032"},{"key":"e_1_3_5_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jvs.2006.02.065"},{"key":"e_1_3_5_8_2","doi-asserted-by":"publisher","DOI":"10.4329\/wjr.v7.i11.375"},{"key":"e_1_3_5_9_2","first-page":"44","article-title":"May-thurner syndrome: can it be diagnosed by a single MR venography study?","volume":"19","author":"McDermott S","year":"2013","unstructured":"McDermott S, Oliveira G, Ergul E, et al.
