Ilio-Hepatic Artery Bypass For Hypoplasia Of The Celiac Axis And Its Branches With An Inferior Pancreaticoduodenal Artery Aneurysm

Hemorrhage due to a ruptured pancreaticoduodenal artery aneurysm is potentially fatal. We describe a case of a 51-year-old man, incidentally diagnosed with an inferior pancreaticoduodenal artery aneurysm associated with probable congenital hypoplasia of the celiac axis and its branches. Considering the rupture risk, we performed an ilio-hepatic artery bypass with an autologous vein graft and aneurysmorrhaphy. The postoperative course was uneventful. At the 24-month follow-up, the bypass was patent, with no aneurysm recurrence. The ilio-hepatic artery bypass is effective and preserves visceral blood flow. However, the iliac artery is susceptible to occlusive disease, and long-term follow-up is required.
