Abstract
Inferior pancreaticoduodenal artery (IPDA) aneurysms have been associated with celiac
axis stenosis and occlusion. Retrograde flow through the IPDA arcade has been hypothesized
to cause enlargement of these vessels and lead to aneurysm formation. However, objective
proof of this hypothesis is lacking, given the fact that celiac stenosis or occlusion
and IPDA aneurysms are typically diagnosed concurrently and recurrent aneurysms have
not been described. This report presents a patient with celiac axis stenosis and an
IPDA aneurysm treated with median arcuate ligament lysis, celiac stenting, and aneurysmectomy.
Seventeen years later, he developed a second IPDA aneurysm treated with a flow diverting
stent.
