Aneurysm of the gastroduodenal artery: an unusual cause of obstructive jaundice.

Splanchnic artery aneurysms are among the most infrequent aneurysms that affect the arterial circulation. Aneurysms of the gastroduodenal artery are the rarest splanchnic artery aneurysms, comprising fewer than 10 per cent of all such lesions. The most typical presentations include abdominal pain and acute gastrointestinal bleeding. However, the diagnosis is often missed preoperatively. We report the successful surgical management of a patient with a gastroduodenal artery aneurysm who presented with isolated obstructive jaundice and review the literature on this unusual finding.
