Artery Bypass Grafting

We describe a rare complication of coronary artery bypass grafting (CABG) in a young man who presented with sudden, severe, bilateral visual loss after surgery. His ophthalmological examination was non-revealing; however, MRI of the brain revealed bilateral occipital lobe infarction. His infarction was presumed to be secondary to emboli arising from surgical manipulation within the atherosclerotic ascending aorta or from a cardiogenic thrombus formed due to perioperative arrhythmia.

Recurrent Angina

Iatrogenic aortocoronary arteriovenous fistula is a very rare complication of coronary artery bypass grafting in which one of the arterial grafts inadvertently forms a fistulous tract with a cardiac vein, shunting blood from the anastomosed coronary artery. We report a patient with an iatrogenic left internal mammary artery graft to cardiac vein fistula presenting with recurrent angina three years after a three-vessel coronary artery bypass grafting.
