Penetration of an Inferior Vena Cava Filter into the Aorta

Transvenous placement of inferior vena cava (IVC) filters is commonly performed in selected patients with deep venous thrombosis and pulmonary embolism. However, filter placement is sometimes associated with serious complications. A common complication is asymptomatic perforation of the IVC and penetration of adjacent organs by the filter. Here, we report a case of an 83-year-old man whose prophylactic IVC filter penetrated the aorta. The patient was closely followed without surgical intervention for more than a year, and no additional complications were observed.
