Surgical removal of stent entrapped in proximal left coronary artery system.

Coronary artery stents were developed to prevent acute coronary closure and reduce restenosis after coronary angioplasty. A well-recognized, although uncommon, complication of stent deployment is loss of control, resulting in the stent being inadvertently deployed in an undesirable location. This case study describes a patient who underwent stent insertion to the left anterior descending artery and had stent entrapment in the left anterior descending/left main coronary artery. The stent was surgically removed, preventing unnecessary bypass grafting to a normal circumflex artery.
