Subclavian artery aneurysm with oesophagoarterial fistula.

Aneurysms of the subclavian artery are rare. Fistula formation between the subclavian artery and the oesophagus has been described in aberrant subclavian artery and oesophageal foreign body. However, a fistula between a non-aberrant subclavian artery aneurysm and the oesophagus has not been previously reported. In this report, an unusual case of subclavian artery aneurysm with a fistula to the oesophagus causing intractable haematemesis is presented with the angiographic findings.
