Innominate artery cannulation for congenital heart disease.
Arterial cannulation of the ascending aorta is the standard for congenital heart surgery. However, in some situations ascending aortic cannulation can be difficult, and cannulation of the innominate artery may be preferable. These situations may include: operations on the ascending aorta, a small ascending aorta which may be obstructed by the arterial perfusion cannula, redo operations where vascular structures including the ascending aorta are adherent to the back of the sternum, and neoaortic calcification in a patient who has undergone a previous Norwood operation. Innominate artery cannulation also permits the use of low flow cerebral perfusion, with avoidance of total circulatory arrest. In neonates and infants, the femoral and axillary arteries are generally too small to permit adequate flows on cardiopulmonary bypass. We describe four cases as examples of operations in which we have found innominate artery cannulation to be advantageous.
