Inferior Vena Cava (IVC) duplication is a well-known anatomic variation that is important when relevant procedures are being planned Duplication of inferior vena cava is a relatively rare vascular anomaly with a prevalence of 1.5% (range 0.2-3.0%). Knowing this anatomical variation is very important in cases of IVC filter placement. . Literature review shows that filter placement in cases of duplicated inferior vena cava has many options like placing it in both vena cavae, suprarenal filter placement or coil-embolization of the inter-venous segment plus placing a filter in the right inferior vena cava. We report a case of newly diagnosed bladder cancer with high risk of thrombosis and a recent massive pulmonary embolism . Patient was planned for transurethral resection of bladder tumor and as a prophylactic measure an IVC filter placement was requested to prevent further pulmonary emboli that might occur during or after surgery.. Cavography showed duplicated IVC and the filter placement was performed in the supra-renal portion and was proved to be an adequate and safe procedure. No procedure related complication was reported. There are few worldwide reported cases of filter placement in a duplicated vena cava and to our best knowledge this is a first case reported in Oman.
