Surgical approach and review of literature on gastroduodenal aneurysm: a case report.

Splanchnic artery aneurysms are relatively uncommon occurrences. The splenic artery aneurysm is the most common, making up 58% of the abdominal visceral vessel aneurysms. This is followed by hepatic artery aneurysm and those of the gastroduodenal (GDA) and pancreaticoduodenal arteries. The GDA artery aneurysm is quite rare. Only 29 had been reported by 1980. We are reporting here a case of GDA aneurysm diagnosed pre-operatively as an aortic aneurysm. We will also review the literature and make note of the changes in pathophysiologic concepts and the diagnosis of GDA aneurysms.
