Transjugular Balloon-Assisted Retrograde Ethylene-Vinyl Alcohol Copolymer Embolization of a Main Pulmonary Artery Defect Discovered during Removal of a Malpositioned Dialytic Central Venous Catheter

An 81-year-old man was referred for removal of a malpositioned left transjugular tunneled dialysis catheter (TDC; Fig 1). No blood was aspiratable from the catheter. Computerized tomography (CT) confirmed its extravascular course: Its leading segment lay interposed between the descending aorta and left main pulmonary artery (LtMPA). Because the patient was stable and mediastinal bleeding was excluded on contrast-enhanced CT (Fig 2), preemptive embolization of the extravascular route during removal was undertaken.
