Abstract:
Anatomic variations of the inferior vena cava (IVC) are found in 3-5% of the population. IVC duplication is a well-known anatomic variation that is important when relevant procedures are being planed. Therefore, the identification of IVC anomalies should be checked prior to pertinent interventions. We report two cases of dual IVC filter placement for duplicated cava including a missing left inferior vena cava and subsequent pulmonary embolism. The rationale of one versus two filters and the current literature are discussed.
