Coronary artery stent fracture with aneurysm formation and in-stent restenosis.
Coronary stent fracture is a relatively rare but potentially serious complication of coronary artery stenting. It has been recognised as a cause of in-stent restenosis as well as acute stent thrombosis. Most fractures occur in stents after aggressive post-dilatation, stents implanted in tortuous and calcified lesions, and after cardiac trauma [M.S. Lee, D. Jurewitz, J. Aragon, J. Forrester, R.R.

Stent fracture and restenosis in the drug eluting stent era. Catheter cardiovasc Interv 2004; 61(1):111-116.]. We report on a case of delayed stent fracture that gradually lead to in-stent restenosis (distal part), significant fragment displacement with the formation of a coronary artery aneurysm that was unsuitable for percutaneous intervention.
