Aortobronchial fistula: a late complication of division of the persistent ductus arteriosus.

An 11-year-old girl had nearly fatal hemoptysis due to false aneurysm and aortobronchial fistula following ductus division 9 years previously. Silk suture material was implicated as a causative agent in association with dilation of the aortic isthmus. To our knowledge, no previous report of this complication exists in the literature. Twenty-two cases of false aneurysm have been described, 86.3% following ligation. The use of elective hypotension during ligation and monofilament suture during division may prevent this serious late complication in the future.
