Inferior vena cava filter migration during the prone position for spinal surgery: a case report

Abstract

The prone position during surgery can induce anatomic and hemodynamic changes in the IVC. This may contribute to the migration of IVC filters--especially flexible retrievable filters. Careful handling and positioning of patients with IVC filters is recommended to avoid a sudden increase in IVC pressure that may predispose to IVC filter migration.

Removal of an inferior vena cava filter that had migrated to the right ventricle by off-pump ventriculotomy and direct-vision snare capture: a novel hybrid technique

“…The method most commonly used to remove an IVCF that has migrated to the right ventricle is endovascular retrieval, and if this fails, an on-pump right ventricular incision is mandatory. 5 However, in the present case, the patient had stage III silicosis and hypoxemia. For patients with high risk factors such as low cardiopulmonary reserve, on-pump extracorporeal life support may not be more beneficial than off-pump procedures.…”

“…4 If this fails, the IVCF can be removed via right ventriculotomy under cardiopulmonary bypass (on-pump). 5 Under certain circumstances, however, the IVCF cannot be retrieved by an endovascular approach, and the patient is too fragile to tolerate extracorporeal circulation because of hypoxemia. We herein report a case of successful removal of an IVCF that had migrated to the right ventricle via a novel hybrid technique of off-pump microinvasive right ventriculotomy combined with catheterized snare capture.…”
