Sixteen aneurysms of the diverticulum of the ductus arteriosus in adults have been previously reported. Ten patients died of rupture of the aneurysm or died at surgical exploration. Only one previous patient underwent successful aneurysmectomy. Five new cases of aneurysm of the adult ductal diverticulum, all diagnosed preoperatively and successfully repaired, are presented. All five patients are alive 6 to 33 months postoperatively. Our experience with these patients suggests several important features of these aneurysms: (1) Diagnosis may be difficult and may require multiple-view aortography or computed tomographic (CT) scanning to differentiate from tumor. (2) The operative approach, either left thoracotomy or median sternotomy, may be determined by the necessity for concomitant procedures. (3) Unlike true atherosclerotic aneurysms of the aortic arch, these aneurysms can be repaired effectively by aneurysmorrhaphy. (4) Because of their critical location and the high incidence of complications in reported cases, aneurysms greater than 3 cm in diameter, those producing symptoms, or those showing progressive enlargement should be surgically resected.
