Migration of Bare-Metal Stent Placed in the Right Iliac Vein Into the Right Pulmonary Artery.

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; it was diagnosed there and subsequently not removed for at least 3 years. Despite reports in the literature for the removal of migrated stents by minimally invasive interventional methods, in our case, that was not possible because of the long period during which the foreign body was in the right pulmonary artery and the proximal partial occlusion of organized mural thrombus.
