[Left main stent avulsion during percutaneous coronary intervention for chronic total occlusion].

We report the case of a chronic total occlusion in the left circumflex coronary artery due to the struts of a stent previously placed on the left main artery. The procedure was complicated by detachment of the stent advanced into the culprit lesion within the struts of the previously implanted stent in the left main artery. The extraction of the lost stent was performed using the twisting wire technique, but this operation resulted in a further complication, i.e. avulsion of the previously implanted stent on the left main artery. The case was resolved favorably with the implantation of a new stent on the left main artery and surgical extraction of the retracted stent from the brachial artery.
