Subclavian-oesophageal fistula as a complication of foreign body ingestion: a case report.

Foreign bodies in the upper aerodigestive tract are very common. In the local community, the commonest foreign body encountered in the oesophagus is the fish bone. Impaction in the thoracic oesophagus can lead to perforation and the subsequent formation of an arterial-oesophageal fistula. Such fistulae are inevitably aorto-oesophageal in nature. A subclavian-oesophageal fistula is described in this patient.
