Wandering stent within the pulmonary circulation

To present a case of a wandering stent within the pulmonary circulation that was managed conservatively with the "wait-and-see" strategy. Accidental dislodgement of a left brachiocephalic vein stent into the left lower lobe pulmonary artery occurred in an 83-year-old patient suffering from end-stage renal disease during placement of a left jugular vein catheter. The following day, a second X-ray revealed migration of the stent from the left to the right lower lobe pulmonary artery. Our patient was managed conservatively with low-molecular-weight heparin and was discharged on clopidogrel. The patient remained asymptomatic with regard to the migrated stent for four and a half years and died of old age. This is the first case of a wandering stent within the pulmonary circulation reported in the literature, supporting the "wait-and-see" policy in the management of such patients.
