The recognition of a double aortic arch which causes significant constriction of the esophagus and trachea is relatively easy if the cardiac symptoms caused by this anomaly are borne in mind. Once suspected, the diagnosis may be confirmed readily by radiographic examination of the esophagus with a barium swallow. The treatment consists of division of the ductus arteriosus (or ligamentum) and of the smaller component, usually the anterior, of the double aortic arch.  相似文献

A newly designed aortic root perfusion cannula (ARC) is described that accomplishes a double purpose. Not only does it allow rapid inflow into the root of the aorta for induction of hypothermic cardioplegia, but it also provides an effective air vent after completion of the procedure. This technique simplifies air venting at the end of open heart operations.  相似文献
