Description
Summary:Arterioportal fistula (APF) combined with a visceral artery pseudoaneurysm is an exceptionally rare and critical vascular disorder of the abdominal viscera, with pseudoaneurysm rupture being potentially fatal and severe APF leading to portal hypertension, both of which necessitate immediate intervention. An 87-year-old woman with a history of pancreatitis presented with upper abdomen and back pain. Laboratory tests revealed elevated amylase levels and severe anemia. A computed tomography (CT) scan showed a large dorsal pancreatic artery (DPA) pseudoaneurysm with a fistula to the main portal vein. Given her advanced age, surgery was deemed high-risk, and endovascular treatment was selected. Transcatheter arterial embolization was successfully performed using coils to embolize the DPA pseudoaneurysm. A follow-up CT 1 week postprocedure confirmed the absence of a pseudoaneurysm and no further progression of anemia.
