Abstract
We present the first case of successfully treated innominate artery dissection as a complication of selective cerebral antegrade perfusion during reoperative aortic valve and hemiarch replacements. Innominate artery dissection was suspected based on unilateral decreases in the right radial arterial pressure and right cerebral oximetry value. Intraoperative ultrasonography demonstrated minimal flow in the right internal carotid. A right aortoaxillary bypass graft was performed leading to immediate improvements in the right radial arterial pressure waveform and right cerebral oximetry. The patient was discharged neurologically intact on postoperative day six.
