| Popis: | Thirty-three neonates treated for reversible respiratory failure underwent reconstruction of their previously ligated right common carotid arteries (RCCAs) immediately after extracorporeal membrane oxygenation (ECMO). Cerebral color Doppler imaging, performed during and repeatedly after ECMO, revealed antegrade flow in the right internal carotid artery (ICA) in all neonates within 6 days after successful RCCA reconstruction. Mean ICA velocity was significantly less in the right artery compared with the left during ECMO and within 1 hour of reconstruction, but there was no difference after 12 hours. In neonates with successful RCCA reconstruction, the flow in the proximal right anterior cerebral artery was antegrade in only 4% of examinations during ECMO but became antegrade in 94% after 6 days. Retrograde flow in the right posterior communicating artery persisted in 50% of examinations performed 1 day after reconstruction. ICA flow become antegrade with symmetric velocities shortly after successful RCCA reconstruction. Collateral flow persists longer but decreases rapidly. |
