Abstract
BACKGROUND: Extraluminal stent migration is exceptionally rare and can lead to severe complications such as vessel closure, coronary thrombosis, and myocardial infarction. CASE SUMMARY: A 68-year-old man who underwent percutaneous coronary intervention (PCI) with stent deployment in the right coronary artery 4 years earlier presented with progressive angina. Initially, he had experienced a stent infection and sepsis shortly after the procedure. Coronary angiography revealed that the stent had migrated to the lung, with chronic total occlusion of the right coronary artery. The patient underwent successful coronary artery bypass grafting and surgical removal of the migrated stent. DISCUSSION: Extraluminal stent migration is often linked to coronary artery aneurysms, arterial injury from balloons or stents, and infections. This case, involving late stent migration into the lung, is the first of its kind documented. TAKE-HOME MESSAGE: The case underscores the need for careful aseptic technique and intravascular imaging during PCI.
