Aneurysms of the Previously Ligated Patent Ductus Arteriosus

Abstract
Five cases of postoperative aneurysm of the ductus arteriosus are presented and discussed, together with 12 from the literature. The ductus had become recanalized in all 17 patients. Infection was present in 11, having existed preoperatively in only two of these cases. The evidence suggests that contamination at the time of surgery was responsible for the infection in at least seven cases.
