There have been few case reports with IVC anomalies and development of deep vein thrombosis. In our comprehensive English language literature review, the earliest reported case of duplication of the inferior vena cava was reported in 1912 in the journal, The Anatomical Record. Over the last 100 years, case series involving IVC duplication in association with venous thromboembolism number less than 10.
