Inferior vena cava filter from left-sided superior vena cava

We describe the unusual case of a 71-year-old male with a history of deep vein thrombosis and recurrent multiple pulmonary embolism (PE) despite adequate anticoagulation. Computed tomography (CT) and brachiocephalic venography revealed a left-sided superior vena cava. We describe successful placement of an inferior vena cava filter via a left-sided superior vena cava.
