Double-arterial cannulation during aortic arch reconstruction in pediatric patients.

Aortic arch reconstruction is a highly demanding procedure in congenital heart surgery. The 2 conventional options for cardiopulmonary bypass - deep hypothermic circulatory arrest or antegrade cerebral perfusion - both result in lack of perfusion of the entire or lower body.  In 2003, the Children's Heart Center Linz started to use a double-arterial cannulation technique for aortic arch reconstructions in order to provide whole body perfusion during the entire operation. Our technique, demonstrated in this video tutorial, is as follows: After inserting an arterial cannula into the innominate artery, followed by venous cannulation, the cardiopulmonary bypass is started. The left pleural cavity is opened directly above the diaphragm. The inferior pulmonary ligament is transected and the descending aorta is then visualized and can be cannulated directly. Both arterial cannulas are linked via a Y-connector. The surgeons in our center have used this method in more than 450 uni- and biventricular newborns and children. There has not been a lethal incident associated with this cannulation technique; one intraoperative lesion of the descending aorta was repaired immediately.  Our double-arterial cannulation technique is a simple and safe method for perfusing the brain and the lower parts of the body during aortic arch reconstruction.
