Two-Stage Hybrid Treatment of Residual Inferior Pancreaticoduodenal Artery Aneurysm Following Treatment of Ruptured Superior Pancreaticoduodenal Artery Aneurysm: A Case Report.

Herein, we describe the case of a 72-year-old man who presented with a residual inferior pancreaticoduodenal artery aneurysm following the rupture and treatment of a superior pancreaticoduodenal artery aneurysm. Open surgery for pancreaticoduodenal artery aneurysms requires carefully planned vascular reconstruction to prevent organ ischemia and minimize pressure changes caused by fluctuations in mechanical stress. Additionally, in cases of rupture, factors such as the patient's condition, presence of hematoma and adhesions, and pressure changes resulting from prior transarterial embolization must be considered. This case report outlines the surgical strategy employed for managing the residual inferior pancreaticoduodenal artery aneurysm.
