Treatment of Proximal Left Anterior Descending Artery Aneurysm by Stent-graft Implantation: A Case Report with Adverse Long-term Outcome

Coronary stenting with stent-grafts have been reported to be a safe and quick treatment option for coronary artery aneurysms although long-term results in large patient groups are not available. We report a case of saccular aneurysm of proximal lefı anterior descending artery (LAD) associated with anterior myocardial infaretion in the absence of any significant stenosis. The aneurysm was successfully obliterated by using a polytetrafluoroethylene-coated coronary artery stent. However, the patient presented with anterior reinfarction two months after stent implantation. Coronary angiography demonstrated sustained occlusion of the coronary aneurysm and severe focal stenosis at the proximal edge of the stent, involving the ostium of LAD. The patient underwent coronary bypass surgery, and he is stili asymptomatic 3 months after the operation.
