We present our first encounter with transient cortical blindness as a neurological adverse complication in a 68-year-old woman five days following coronary artery bypass grafting. This transient neurological complication may have been a result of microembolization following coronary angiography, cardiopulmonary bypass or setting of hypertension, diabetes mellitus and renal disease that affect on vertebrobasilar vascular system. This was our first experience of this complication in over 18,000 cardiac surgeries.References
