Aneurysms of the pancreaticoduodenal artery associated with occlusion of the celiac artery

Aneurysms of the pancreaticoduodenal artery are rare and may be associated with celiac artery stenosis or occlusion. Twenty-eight patients are reported in the literature. The diagnostic findings and therapeutic alternatives of four additional patients form the basis of this report. One patient with ruptured pancreaticoduodenal aneurysm was successfully treated by transcatheter embolization, and one patient was treated surgically; both patients had an uneventful recovery. In the remaining two patients, the aneurysms were left untreated. One patient died 1 year later of an unrelated cause, and the other patient is symptom-free after 2 years.
