Right common carotid artery ligation in extracorporeal membrane oxygenation.
The effect of right common carotid artery ligation required for arteriovenous extracorporeal membrane oxygenation (ECMO) was investigated in 35 infants. Their neonatal course was reviewed for evidence of right-sided ischemia of the brain, as suggested by the presence of focal seizures, hemiparesis, focal abnormalities on electroencephalography, or infarct or hemorrhage demonstrable on neuroimaging studies. A significant incidence of left focal seizures (9/35) versus right focal seizures (2/35) was noted, suggesting an effect of the carotid ligation on right hemisphere function. Computed tomographic scans (20/35 infants), electroencephalograms (18/35), ultrasound scans (31/35), and neurologic examinations did not reveal an increased incidence of right hemisphere abnormalities. These data suggest that systematic evaluation of the effects of right common carotid ligation should proceed as discussion continues on expanding the use of ECMO.
