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