Acute thrombosis after endarterectomy of stented left anterior descending artery.

Acute thrombosis of the endarterectomized coronary artery is a serious complication after coronary endarterectomy. Herein, we describe a case of a 65-year-old man who had undergone percutaneous stent implantation in the left anterior descending artery, then after he received an endarterectomy with the removal of stents severe in-stent restenosis occurred. Three days after the operation, sick sinus syndrome developed with acute myocardial infarction. Coronary angiography revealed thrombosis at the reconstructed site of the left anterior descending artery. Pacemaker implantation, intra-aortic balloon pumping, and aggressive anticoagulation produced recanalization of the left anterior descending artery.
