Pseudoaneurysms of abdominal aorta after inferior vena cava (IVC) filter placement are uncommon, with associated morbidity and mortality. We report a case in which an abdominal aortic pseudoaneurysm resulted from erosion of a Bird's Nest (Cook, Bloomington, IN) IVC filter into the wall of the abdominal aorta. A 64-year-old woman with an IVC filter placed 10 years prior presented to the emergency department complaining of abdominal pain. A computed tomography scan of the abdomen and pelvis showed a 1.4-cm x 2.0-cm infrarenal aortic pseudoaneurysm adjacent to the IVC filter site. A Zenith endograft (Cook) was used via an open femoral artery exposure to successfully treat the pseudoaneurysm.
