Surgical removal of a stent entrapped in the left main coronary artery.

A stent entrapped in the coronary artery, which can not be removed by a trans-catheter approach, is extremely rare but is the biggest problem cardiologists face. Surgical retrieval appears to be the only possible treatment to avoid sudden death due to stent thrombosis. We experienced with a New Parmaz-Schatz stent entrapped in the left main coronary artery (LMT) of a 65-year-old man. He underwent surgical removal of the stent with ascending aorta incision and double coronary artery bypass grafting (CABG) using saphenous veins. We believe that a stent entrapped in the LMT must be removed as rapidly as possible to avoid sudden death. Furthermore, in order to avoid the risk of peripheral thrombosis, retrieval is also the case in patients whose distal coronary flow can be maintained with CABG.
