Coronary Artery Aneurysms Following Stenting

Coronary artery aneurysms are rare complications following stenting and were reported with drug-eluting as well as bare metal stents. They can be asymptomatic or present as acute coronary syndromes and usually detected during coronary angiography. The mechanisms responsible can be vascular trauma, hypersensitivity to drug, polymer, or metal. Rarely, it can be due to acute bacterial infections resulting in mycotic aneurysms. Management depends on symptoms, presentation, and underlying pathology and has to be tailored on a case-to-case basis.
