Migration of an Inferior Vena Cava (IVC) Filter Into the Intrahepatic IVC: A Case Report.

The use of Inferior Vena Cava (IVC) filters is increasing for patients who cannot otherwise receive anticoagulation for a deep vein thrombosis (DVT) or pulmonary embolism (PE). In this case, a 60-year-old man presenting with abdominal pain was found to have migration of his IVC filter into his intrahepatic IVC. Interventional radiology (IR) and vascular surgery were consulted as the migrated IVC filter was felt to be the likely cause of the patient's pain. Consideration was given to transferring the patient to a liver transplant center to retrieve the migrated filter. When patients with a history of IVC filter placement present to the emergency department, a high index of suspicion for IVC filter complication should be maintained and there should be a low threshold for ordering CT imaging. If a severe IVC filter complication is discovered, patients may ultimately require transfer to a center with hepatic surgery capability for definitive treatment given the complex vasculature involved.
