Endovascular retrieval of an inferior vena cava filter penetrating the false lumen of a chronic aortic dissection, with concomitant iliocaval reconstruction

Inferior vena cava filter (IVCF) placement is indicated in patients with acute venous thromboembolism who cannot be adequately anticoagulated or have failed anticoagulation. Prompt IVCF retrieval decreases the risk of complications associated with longer dwell times including fracture, penetration, and further thromboembolic events. Endovascular IVCF retrieval has been performed despite penetration into adjacent structures including the aorta; however, penetration into the false lumen of an aortic dissection is rarely seen. This case report describes endovascular management of an 11 year old IVCF that caused iliocaval thrombosis and penetrated the false lumen of a chronic type B aortic dissection.

Balloon-assisted inferior vena cava filter retrieval: A novel technique to enhance irretrievable filter extraction

Although the use of inferior vena cava (IVC) filters has expanded, complications have led to the recommendation to remove all unnecessary filters. Several techniques exist to aid in retrieving irretrievable IVC filters. The balloon-assisted retrieval technique has previously been described to aid in cases of an embedded hook. This report describes an alternative use of the balloon-assisted technique, specifically to aid in the retrieval of Greenfield IVC filters in cases of strut perforation of the cava wall. This technique was successfully performed in six out of six attempted cases with no associated complications.
