Carotid artery repair after pediatric extracorporeal membrane oxygenation.
Extracorporeal membrane oxygenation (ECMO), which has been shown to dramatically improve survival in selected neonatal patients, is now being used in some centers for pediatric patients with respiratory and cardiac failure. One of the major concerns with ECMO support is the permanent ligation of the right common carotid artery. We have used ECMO to support 10 pediatric patients with cardiac failure and 22 patients with respiratory failure. Thirty-one were cannulated via the common carotid artery and internal jugular vein on the right. Five of the last six patients with respiratory failure survived. One was on ECMO for 21 days, so the carotid artery was not amenable to repair. In the other four survivors the common carotid artery was reconstructed at the time of decannulation. In one patient, a segment of the artery was resected because of an intimal injury, and a primary anastomosis was performed. In all four, color Doppler studies of the artery prior to discharge were normal. None had clinical evidence of emboli, and a cranial computed tomography (CT) scan was normal in all four patients. These data suggest that in many pediatric patients supported with ECMO, reconstruction of the common carotid artery can be performed with low risk of embolic complications. Long-term follow-up is needed.
