Perioperative neurologic injury is a devastating complication that is not always predictable, but contributes to significant morbidity, mortality, and consumption of health care dollars.1 The etiologies for stroke and neurocognitive dysfunction following cardiac and non-cardiac surgeries are broadly divided into embolic and perfusion related insults. Epiaortic ultrasound, transcranial Doppler, and screening carotid ultrasonography may reduce the incidence of perioperative neurologic injury by targeting larger arterial vessels (aorta, middle cerebral, and carotid arteries, respectively) for embolic sources of cerebral injury using ultrasound technology. Diffuse insults and subtle neuro-cognitive deficits suggest an etiology related to regional cerebral microcirculation perfusion imbalance. In their prospective study of over 11,000 patients, Likosky and colleagues found that 75% of strokes occur among the 90% of p...
