Long-standing stenosis of the celiac axis is a rare cause of aneurysm of the inferior pancreaticoduodenal artery, which serves as a collateral pathway; the etiology is believed to be due to turbulence from increased blood flow. The authors describe 2 cases of such aneurysm, which ruptured in the retroperitoneum and were treated with transcatheter embolization.
