Brief Summary:
Extra corporeal membrane oxygenation (ECMO) is a transient supplementation technique that alleviates hemodynamic and ventilatory failure. Its implementation requires carotid arterial and jugular venous cannulation in newborns or children weighing less than 20 kg. The impact of ECMO on arterial circulation was studied by Doppler ultrasound and shows a redistribution of flows within the circle of Willis.
This study aims to model cerebral flow in children who have been cared from jugulocarotid ECMO and compare cerebral hemodynamics according to the technique of reconstruction of the common carotid artery after decanulation (reconstruction or ligation).
Detailed Description:
Extra corporeal membrane oxygenation (ECMO) is a transient supplementation technique that alleviates hemodynamic and ventilatory failure. Its implementation requires carotid arterial and jugular venous cannulation in newborns or children weighing less than 20 kg. The impact of ECMO on arterial circulation was studied by Doppler ultrasound and shows a redistribution of flows within the circle of Willis.
When ECMO is stopped, carotid decanulation is done either by ligation or by reconstruction, depending on the practices of the surgical team and the peroperative findings. The reconstruction allows a restoration of blood flow to the internal carotid artery and the middle cerebral artery with a disappearance of compensation by the circle of Willis.
Vascular flow modeling is a computational method derived from imaging for the hemodynamic study of fluids, including pressures and flow rates at different points in a vessel. Data from the literature on the modeling of cerebral vascularization in newborns are scarce.
This study aims to model cerebral flow in children who have been cared from jugulocarotid ECMO and compare cerebral hemodynamics according to the technique of reconstruction of the common carotid artery after decanulation (reconstruction or ligation).
