Fracture of coronary artery sirolimus eluting stent with formation of four aneurysms.

Coronary stent fracture is a relatively rare but potentially serious complication of coronary artery stenting, in particular with sirolimus-eluting stents. It has been recognized as one possible cause of in-stent restenosis as well as acute stent thrombosis. The formation of coronary artery aneurysm is one of the critical complications after percutaneous coronary intervention and it has been described after a stent fracture too. We report here a case of formation of four coronary artery aneurysms associated with the fracture of a sirolimus-eluting stent.
