Abstract: Visceral artery pseudoaneurysm (VA-PSA) is an uncommon but life-threatening complication of acute-on-chronic pancreatitis, particularly in the presence of walled-off necrosis (WON). Early radiological recognition is essential because of the high risk of rupture. We present the case of a 51-year-old man with chronic pancreatitis who developed a pseudoaneurysm arising from the proper hepatic artery within a pancreatic head necrotic collection. Follow-up contrast-enhanced computed tomography (CT) demonstrated a new arterial-phase enhancing focus within the WON. Digital subtraction angiography (DSA) confirmed the pseudoaneurysm, which was successfully excluded with a covered stent placed via a right transfemoral approach. Post-procedural recovery was uneventful, and short-term follow-up CT showed persistent exclusion of the lesion.
