Carotid artery stenosis at the time of coronary artery bypass grafting is a risk factor but not a cause for peri-operative stroke

Narayan et al. evaluated whether or not carotid artery screening at the time of coronary artery bypass grafting (CABG) influences neurological outcomes [1]. Two of the four strokes in the group with moderate/severe carotid stenosis occurred on the ipsilateral side of the carotid artery lesion, while two were in areas not related to the side of the carotid artery stenosis. In the group with no significant carotid artery stenosis, 18 patients had a stroke of which 16 were ischemic and 2 were hemorrhagic [1].
