Inferior vena cava filter misplacement in the right ovarian vein and successful removal by loop-snare technique in a patient with inferior vena cava agenesis.

Misplacement of an inferior vena cava (IVC) filter in a gonadal vein is a rare complication of IVC filter placement. We report a case of a filter misplaced in the ovarian vein of a pregnant woman with agenesis of the infrarenal IVC and bilateral lower extremity deep venous thrombosis. The filter was removed by a loop-snare technique through an internal jugular vein. IVC agenesis and dilated right gonadal vein should be kept in mind when an IVC filter is being inserted in the infrarenal location through the jugular approach.
