With advances in radiological techniques and diagnosis, more and more types of DIVC were identified and diagnosed. Recognition of the variety of DIVC seen on imaging is essential for subsequent venous interventions.<\/jats:p><\/jats:sec><jats:sec><jats:title>Case presentation<\/jats:title><jats:p>A 77-year-old man presented with low back pain with left lower limb pain for 1 month. Scattered petechiae above the skin surface on the left lower leg, especially on the extensor surface, with flaking and mild tingling of the skin, were noted 3 weeks ago. Ultrasound revealed deep vein thrombosis (DVT) in the left lower limb. Computed tomography pulmonary angiography (CTPA) suggested no significant thrombus in the pulmonary artery. Computed tomography venography (CTV) of bilateral lower limbs showed that iliac vein compression syndrome with formation of deep and superficial venous traffic branches in bilateral lower limbs, predominantly on the left side. CTV of the inferior vena cava (IVC) suggested that the left common iliac vein crossed the common iliac artery bifurcation from dorsal to ventral and continued to travel cranially as a ventral vessel, and connected with the ventral IVC anterior to the right common iliac artery. The right common iliac vein extended cephalad as a dorsal vessel, which was narrowed at the level of 4th lumbar vertebra by compression of the hyperplastic bone and the osteophyte. The patient was discharged after right and left common iliac vein angiography and balloon dilation of bilateral common iliac vein.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>The formation of both ventrally and dorsally aligned DIVC is rarer. It should be clarified the effects of DIVC on DVT formation, and the importance of imaging for preoperative planning.<\/jats:p><\/jats:sec>","DOI":"10.3389\/fcvm.2023.1298071","type":"journal-article","created":{"date-parts":[[2023,12,4]],"date-time":"2023-12-04T06:57:15Z","timestamp":1701673035000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":4,"title":["Case Report: Imaging features of a new type double inferior vena cava malformation and review"],"prefix":"10.3389","volume":"10","author":[{"given":"Yu-lin","family":"Wu","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guo-kai","family":"Yang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qian","family":"Chen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yi","family":"Tang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jian-hui","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shao-jie","family":"Wu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sen-lin","family":"Cai","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yan-feng","family":"Zhou","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yao-Bin","family":"Zhu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jie-wei","family":"Luo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhu-ting","family":"Fang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2023,12,4]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"372","DOI":"10.1016\/j.avsg.2021.07.029","article-title":"Anomalies of inferior vena cava: implications and considerations in retroperitoneal surgical procedures","volume":"79","author":"Nigro","year":"2022","journal-title":"Ann Vasc Surg"},{"key":"B2","first-page":"51","article-title":"Double inferior vena cava and its implications during endovascular and surgical interventions: a word of caution","volume":"29","author":"Shammas","year":"2017","journal-title":"J Invasive Cardiol"},{"key":"B3","doi-asserted-by":"publisher","first-page":"475","DOI":"10.1002\/ar.1090061203","article-title":"Duplication of the inferior vena cava in man","volume":"6","author":"Givens","year":"1912","journal-title":"Anat Rec"},{"key":"B4","doi-asserted-by":"publisher","first-page":"1087","DOI":"10.4067\/S0717-95022016000300044","article-title":"Double inferior vena cava detected by CT venography and confirmed by magnetic resonance venography: embryogenesis and literature review","volume":"34","author":"Hadidi","year":"2016","journal-title":"Int J Morphol"},{"key":"B5","doi-asserted-by":"publisher","first-page":"482","DOI":"10.21037\/cdt.2016.11.18","article-title":"Congenital anomalies of the IVC-embryological perspective and clinical relevance","volume":"6","author":"Ghandour","year":"2016","journal-title":"Cardiovasc Diagn Ther"},{"key":"B6","doi-asserted-by":"publisher","first-page":"5","DOI":"10.24425\/fmc.2020.135009","article-title":"Duplication of the inferior vena cava: evidence of a novel type IV","volume":"60","author":"Klinkhachorn","year":"2020","journal-title":"Folia Med Cracov"},{"key":"B7","first-page":"141","article-title":"Duplication of the inferior vena cava\u2013report of a rare congenital variation","volume":"5","author":"Banerjee","year":"2012","journal-title":"Int J Anat Var"},{"key":"B8","doi-asserted-by":"publisher","first-page":"147","DOI":"10.2535\/ofaj.88.147","article-title":"Double inferior vena cava with interiliac vein: a case report and literature review","volume":"88","author":"Chen","year":"2012","journal-title":"Okajimas Folia Anat Jpn"},{"key":"B9","doi-asserted-by":"publisher","first-page":"669","DOI":"10.1148\/rg.283075101","article-title":"Imaging the inferior vena cava: a road less traveled","volume":"28","author":"Kandpal","year":"2008","journal-title":"Radiographics"},{"key":"B10","doi-asserted-by":"publisher","first-page":"481","DOI":"10.1002\/jcu.1870200713","article-title":"Ipsilateral duplication of the inferior vena cava","volume":"20","author":"Doyle","year":"1992","journal-title":"J Clin Ultrasound"},{"key":"B11","doi-asserted-by":"publisher","first-page":"1159","DOI":"10.1148\/radiographics.13.5.8210598","article-title":"US case of the day.
