Ductus diverticulum aneurysm and coronary stenosis: repair using circulatory arrest

The case of a 68-year-old man with advanced symptomatic coronary artery disease and large aneurysm of the diverticulum of the ductus arteriosus is presented. Both the coronary artery disease and the aneurysm were successfully repaired at the same time via median sternotomy using cardiopulmonary bypass and a brief period of profound hypothermic circulatory arrest. To our knowledge, this is the 27th reported case of such an aneurysm in an adult.
