Inferior vena cava filter thrombosis and suprarenal caval stenosis: a double whammy.

I nferior vena cava (IVC) thrombosis associated with filters is not uncommon in clinical practice. However, suprarenal extension of the thrombosis to the hepatic segment of the IVC is very rare, particularly in absence of renal or hepatic tumors (1). Benign intrinsic IVC stenosis is a rare anomaly that has been associated with IVC thrombosis (2). We describe a case of extensive IVC thrombosis secondary to perihepatic IVC stenosis (documented by intravascular ultrasound [IVUS]) and a permanent
