Iliac vein compression syndrome (IVCS) is a pathological condition in which a blood clot is formed due to blood flow obstruction when the left common iliac vein is compressed between the right common iliac artery and the vertebral body. Therefore, right-sided IVCS (RIVCS) is rare. The effectiveness of treatment for RIVCS has not been sufficiently investigated.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Case summary<\/jats:title>\n                  <jats:p>A 51-year-old man developed deep vein thrombosis in the right lower extremity and non-massive pulmonary embolism during steroid treatment for IgA nephropathy. Magnetic resonance angiography (MRA) suggested iliac compression syndrome. Symptoms improved with the use of direct oral anticoagulants and compression stockings. At the 8-month follow-up, the clinical course was uneventful.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Discussion<\/jats:title>\n                  <jats:p>The causes of RIVCS in this case are believed to be the effects of steroids, prolonged sitting, and compression of the right external iliac vein. However, considering that deep vein thrombosis did not form in the left lower limb where there was no venous compression, it can be considered that the compression of the right external iliac vein had a significant impact. This case has been followed up for 8 months with anticoagulants and is progressing well. This is the first case to report the course of RIVCS treated conservatively with anticoagulant therapy for 8 months. This case suggested that conservative treatment is effective for RIVCS.<\/jats:p>\n               <\/jats:sec>","DOI":"10.1093\/ehjcr\/ytae011","type":"journal-article","created":{"date-parts":[[2024,1,10]],"date-time":"2024-01-10T01:09:35Z","timestamp":1704848975000},"source":"Crossref","is-referenced-by-count":2,"title":["Right-sided iliac vein compression syndrome: when the vein is compressed between the internal and external iliac arteries\u2014a case report"],"prefix":"10.1093","volume":"8","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3154-1267","authenticated-orcid":false,"given":"Tetsuo","family":"Yamanaka","sequence":"first","affiliation":[{"name":"Department of Cardiology, Tokyo Teishin Hospital , 2-14-23 Fujimi, Chiyoda-ku , Tokyo 102-8798, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tatsuhiko","family":"Ishihara","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Kanto Central Hospital of the Mutual Aid Association of Public School Teachers , 6-25-1 Kamiyouga, Setagaya-ku , Tokyo 158-8531, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Toru","family":"Hara","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Tokyo Teishin Hospital , 2-14-23 Fujimi, Chiyoda-ku , Tokyo 102-8798, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yoshimaro","family":"Ichinohe","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Tokyo Teishin Hospital , 2-14-23 Fujimi, Chiyoda-ku , Tokyo 102-8798, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Toru","family":"Fukatsu","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Tokyo Teishin Hospital , 2-14-23 Fujimi, Chiyoda-ku , Tokyo 102-8798, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2024,1,9]]},"reference":[{"key":"2024011807150952400_ytae011-B1","first-page":"7","article-title":"Endovascular intervention for deep vein thrombosis","volume":"44","author":"Okada","year":"2004","journal-title":"J Jpn Coll Angiol"},{"key":"2024011807150952400_ytae011-B2","doi-asserted-by":"crossref","first-page":"419","DOI":"10.1177\/000331975700800505","article-title":"The cause of the predominantly sinistral occurrence of thrombosis of the pelvic veins","volume":"8","author":"May","year":"1957","journal-title":"Angiology"},{"key":"2024011807150952400_ytae011-B3","doi-asserted-by":"crossref","first-page":"363","DOI":"10.1016\/j.avsg.2019.05.033","article-title":"Diagnosis and treatment of nonthrombotic right iliac vein compression syndrome","volume":"61","author":"Chen","year":"2019","journal-title":"Ann Vasc Surg"},{"key":"2024011807150952400_ytae011-B4","doi-asserted-by":"crossref","first-page":"471","DOI":"10.1177\/0268355515598700","article-title":"Compression of the right iliac vein in asymptomatic subjects and patients with iliofemoral deep vein thrombosis","volume":"31","author":"Chen","year":"2016","journal-title":"Phlebology"},{"key":"2024011807150952400_ytae011-B5","doi-asserted-by":"crossref","first-page":"351","DOI":"10.7134\/phlebol.22-4-351","article-title":"Right sided iliac compression syndrome","volume":"22","author":"Toguchi","year":"2011","journal-title":"Jpn J Phlebol"},{"key":"2024011807150952400_ytae011-B6","doi-asserted-by":"crossref","first-page":"314","DOI":"10.1016\/j.jvscit.2019.02.006","article-title":"Diagnosis and management of right external iliac vein \u201csandwich\u201d: a rare cause of iliofemoral deep venous thrombosis","volume":"5","author":"Tai","year":"2019","journal-title":"J Vasc Surg Cases Innov Tech"},{"key":"2024011807150952400_ytae011-B7","doi-asserted-by":"crossref","first-page":"291","DOI":"10.1177\/096721090201000319","article-title":"Arterial compression of the right common iliac vein;
