Migration of bare-metal stent, placed in the right iliac vein into the right pulmonary artery

Abstract Stent migration is a rare event with potentially serious complications including cardiac arrhythmias and heart failure. We report a case of migration of arterial stent, placed in the right iliac vein into the right pulmonary artery which was diagnosed there and subsequently not removed for at least 3 years. Despite reports in the literature for the removal of migrated stents by mini-invasive interventional methods, in our case, this was not possible, because of the long period for which the foreign body was in the right pulmonary artery and the proximal partial occlusion of organized mural thrombus.
