title: An interesting anatomic variant of inferior vena cava duplication: case report and review of the literature.
abstract: Congenital anomalies of the inferior vena cava (IVC) occur in roughly 4% of the population. We report an interesting case of an atypical variant of duplicated IVC. A 20-year-old man presented with orthopedic injuries and intracranial hemorrhage following a motorcycle accident. He was taken to the fluoroscopy suite for IVC filter placement; duplication of the IVC was noted. The right and left iliac veins shared a normal confluence but two IVCs drained independently into renal veins before reuniting into a single structure. Both IVC filters were placed via a single puncture in the groin. We performed a search of the PubMed database using‘ inferior vena cava duplication’ and reviewed common anomalies of the IVC. Several variants of duplicated IVC exist; the most common of which is two distinct IVCs that arise from each iliac vein without a normal confluence. Our patient had a unique anomaly which allowed filter placements from a single puncture.
