Immediate vein graft thrombectomy for acute occlusion after coronary artery bypass grafting

A 76-year-old man underwent coronary bypass grafting 3 days after exposure to heparin. Immediately after chest closure, he developed acute graft thrombosis and cardiac arrest in the setting of thrombocytopenia. Immediate graft thrombectomies were performed. Postoperative tests for heparin-induced thrombocytopenia and thrombosis (HITT) were positive. This case represents a dramatic example of HITT after coronary revascularization.
